Hmm, not really looking to actually build a computer. I don't really intend to use it for gaming, I just want something that handles things like firefox/streams like hulu or twitch/ and programs such as Photoshop better than the computer I'm using now. Like 2x better than mine seems ideal if I can get it for a good price. It's not like my current computer can't handle that but I'd just like something with a little more power and consistency that doesn't crash as often as mine. I've gotten a little too use to things like firefox not responding or flash crashing.

I guess my problem is that I don't know enough about computer specs to get the ideal one for me. I mean I saw that listing and thought that it having 4x as much HDD space as mine as mine (1 TB to 250GB) 2x the processor speed (Dual-Core 3.20 GHz to Dual-Core 1.60GHz) and 4x the memory (4GB RAM to 1GB RAM) would be a good deal for that price. I really don't know what else I should be looking at.

I was hoping that being mine is over 6 years old and with the continuing advancement of computers that I could find a superior one than what I have right now that does what I want it to do for around $200. If there isn't anything that fits then I'll just keep using what I have now.

The thing is that you bought a pretty meh PC before and you're looking to replace it with another terrible PC that's slightly better but still old and not very good. The clock speed being double doesn't mean much for performance. If you can stretch your budget a little there will be some inexpensive machines available on sites like the Dell outlet that will be perfectly capable and completely blow away what you're looking at.

http://outlet.us.dell.com/ARBOnlineSales/Online/InventorySearch.aspx?brandId=2202&c=us&cs=22&l=en&s=dfh

Ideally you want at least an i3, but the cheapest one at the time of posting is $409. That's not the best pricing and you will see a lot of flucuation in their stock. The great part about the Dell outlet is that you get a standard warranty against parts failing and you don't have to build anything. The parts picking thread is a better place for "what PC should I get" discussions in general, however, even if you're buying a prebuilt system. Get some more information and advice before you put your money down (but in the parts picking thread).

Not only has positional audio simulation via DSP been a thing since the 90s, but some headphones actually do have full sets of surround drivers in them.

We only have two ears, yet they are nevertheless capable of hearing position in 3D space. With control of the source and environment (e.g. in a closed earphone cup) you can do the same thing with the source that the receivers do.

I'm curious, how did you exactly find the number count? Did you convert the RAW values? How would I go about finding the detailed numbered information you found?

The raw values are in hexadecimal (base-16). You can convert it with most calculators that support hex (the windows one will do it in programmer mode, just hit the hex radio button and type in EA then hit the dec radio button) or you can do it manually. The rightmost place in base 16 is the one's place and the second is the 16s place (like the rightmost digit in base 10 is the one's place and the next is the tens place). So you've got E 16s and A 1s, (in hexadecimal, numbers above 9 are represented as letters - A (which is 10), B (11), C (12), D (13), E (14), F (15)).

E 16s is 14 * 16 = 224 and A ones is 10 * 1 = 10. Add these up to get 224 + 10 = 234. Most programmers I know who work with hex regularly tend to just convert back and forth with a calculator because as you can see it'll get tedious when you get to the next digit which is the 256s place and beyond.

I was cleaning my rather dusty computer, wiping down fans and such. In a misguided attempt to get at the CPU fan better (with a microfiber cloth, no vacuum cleaner involved) I ended up loosening the heat sink. Once I realized this is secured it back in place. I don't conclusively know if the thermal paste was dislodged or shifted or something, but after finishing my cleaning and reconnecting everything my computer gave me a temperature warning in the bios startup. At this point I had a choice to 'press any key to continue' or just switch my computer off. I opened the case, all the fans seemed to be giving good airflow, so I let it continue to boot. It shut itself off about twenty seconds after windows was fully running, before I got a chance to check temperature sensors.
My technical proficiency with hardware is growing but I've never applied thermal paste or installed a CPU, and this computer's CPU/heatsink have been undisturbed since they were built (in 2009).
Is it probable that the heat-sink is no longer well seated on the CPU? (I am supposing yes)
I assume SH/SC has an apropriate thread but browsing unfamiliar sub forums on my phone is not super easy.
What do I need to know to pick out and apply the appropriate thermal paste? I assume I need to clean off the old stuff?

If you don't have thermal paste handy, pretty much any brand works (until it heats up and gets weird, stuff like toothpaste and mustard are comparable to many thermal compounds: http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-January-2012/1468/5 ). So pick up whatever you can find easily and don't spend a ton on THE BEST because it may be a couple of degrees difference from generic stuff (which is about the same as mayo?)

I typically use arctic silver 5 or arctic silver ceramique because I bought syringes of them for 8 bucks or something years ago that seem to be nearly endless. To clean off the old thermal paste, mechanically unmount your heatsink (how you do this depends on what kind of socket and cooler your system has). Clean the top of the CPU and the bottom of the heatsink with something lint free (coffee filter, good quality paper towel, avoid things like tissues) with high % rubbing alcohol. If it's goopy I tend to do a lifting-rolling style to get the bulk off, then get a clean paper towel and wipe down to get the surfaces clean. After they're both clean and dry (should be dry very quickly with rubbing alcohol) put some thermal paste on the cpu lid in a pea sized dot in the middle and remount the heatsink. Don't put it down and pick it back up as you'll get air bubbles which may be your current problem (also your old paste likely hardened up some to make this more likely). Just put it down on there and do the mechanical stuff to get it stuck down. If a tiny amount of compound squeezes out of the sides it's fine. If a lot does then you may have used too much.


Here's a little video of a guy doing it:
https://www.youtube.com/watch?v=8rn0BqMyXBM

Note that when he removes it to check how the paste spread he's just doing it for the video and would then have to clean and reapply it to use his system.

I have a Lenovo Edge S430, but it's a bit slow compared to the Macbooks around me. I'm thinking of upgrading it by replacing the SATA hard drive with an SSD. The computer came with a 16 gig SSD drive used for cache and some other stuff, but I'm wondering if it'd be feasible and/or even possible to either put in a larger SSD in place of the 16 gig one, or just replace the SATA drive. I'm not sure if it'd fit. Anyone know?

You can do either or both. Right now you have a 2.5" sata hard disk and a mSATA SSD. Your model of laptop's specs are on pg 26 of:
http://www.lenovo.com/psref/pdf/edgebook_WE.pdf

The easiest thing is to replace the regular hard disk with a SSD. It would go something like this:
docs: http://support.lenovo.com/us/en/documents/pd024447
movie: http://support.lenovo.com/us/en/videos/pd027000

plus moving the installation over with drive imaging software and a USB to sata adapter (or using desktop computer with two free sata ports).

If you want to replace the cache SSD in the mSATA slot that is also an option. You'd disable Express Cache software to stop it from using that as a cache disk and install another SSD in the slot.
The msata replacement is under the keyboard, see the bottom 1/3 of this page:

I've currently got 2x http://www.kingston.com/us/hyperx/memory/predator dual channel because I hosed up when I first bought them some time ago. Their total capacity should be 16GB, but only 7.96 GB Ram is usable. Can someone here help me?

Motherboard

It could be a number of things, although if the memory's plugged in correctly you should have 16gb available. Do you have the memory in the correct slots? I notice it says it's running in single channel. The manual for that motherboard has an atrocious online version but you usually would put the ram in slots 2 and 4, or 1 and 3 (1 being closest to the CPU socket) to operate in dual channel. Have you reseated the RAM and tried it in different slots? Also, what voltages are you running at and what speed?

Thanks for the reply! Here's a paste with all the cpu-z info:
http://pastebin.com/QCEcLbpS

I've tried switching their slots to the extent that I can. And it doesen't yield other results than the current. Info on the voltage should be found within the paste :).

I've done a little research and the main list of issues that it could be are:
1) You have Windows 7 Home Basic installed which has an 8gb memory limit - http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx#physical_memory_limits_windows_7
2) Your CPU has a broken off pin - http://vip.asus.com/forum/view.aspx?id=20120513011344318&board_id=1&model=SABERTOOTH+990FX&page=1&SLanguage=en-us
3) You have a faulty motherboard
4) You need to increase the RAM voltage - in your pasted CPU-Z link it shows the DRAM voltage is currently 1.49 (probably 1.5 in actuality). So you're not using your XMP profile but with 4 sticks of ram sometimes systems need a little more voltage to help. Go into the BIOS and up the RAM voltage a little bit. The XMP Profile will set it to 1.65 so that may be one way to go, but it's not guaranteed to work since it's supposed to be 1.65V to remain stable at the higher clock speed that ram is rated for.

I don't even know if it's possible to buy Home Basic so that may not be it. In the linked thread from the ASUS support forum the guy finally found that he had broken a pin on his CPU and was actually able to get a jeweler to solder it back on, but the other suggestions were made in various posts in that thread as well with regards to a bad motherboard or needing a voltage bump.

As an aside, you should definitely stop by the PC Parts Picking Megathread before you build your next PC. You've made a number of questionable choices with your current build.

Bad memory can lead to a computer shutting down, right? Sometimes it reboots, sometimes it stays off.

The only change I can think of is that I upgraded my ram from 4gb to 8gb a few months ago. Tends to happen during heavy RAM usage periods, but sometimes it will occur overnight when nothing is running except torrents.

Is there any sort of memory test I can run to see, short of digging up my old ram sticks and seeing if the problem persists?

Bad memory can cause that, although usually you'd see a windows bluescreen that you could look at in the windows event log to see the cause of. Shutting right down tends to be more related to power supplies. That said you can test your memory. Create a Memtest86+ boot disc and run it for as long as you can stand and see if there are errors or bad PC behavior:
http://www.memtest.org/

I like to give new PCs 20+ hours of burn-in time with it but I've personally never seen a problem show up beyond 5 hours into a run. Overnight should do it. If you get any errors or crashes there's some kind of hardware problem. With memory errors it's usually the RAM, Motherboard or CPU. If it shuts off it could be those or more likely the power supply.

This isn't just a hardware issue, but I'm not seeing a better place to ask so I hope it's not too bad to post here.

My external HDD fell on the floor while writing the other day, and now I'm looking to save what data I can (it's already painfully slow and having obvious bad sector issues. with the surface scan showing an approximate 90 hours to finish). I have a couple of USB drives, total capacity of 32 GB, and I hope I'll be able to salvage more when I have the replacement drive here.
Is there a utility that will allow me to pick what folders I want to save to the USB drives, without accessing the drive itself via Windows Explorer, since it is being incredibly slow? I mostly want to save some stuff for university, some hard-to-find stuff, etc. I have used R-Tools in the past to salvage a good portion of a previous drive, but I'm not sure if it had that functionality.

I've had good luck with Roadkil's unstoppable copier on a sd card and also a hard disk that was developing bad sectors as it was used (freezer trick):
http://www.roadkil.net/program.php/P29/Unstoppable%20Copier

If you're not ready to copy your stuff off of your disk yet turn it off to prevent further damage; just being on could be destroying it as you've most likely had a head hit the platter, which not only damages both but pollutes the inside of the drive with bits of stuff. They're built in a clean room environment to extremely tight tolerances and don't like random stuff rattling around inside them.

As for keeping it on... I know I should turn it off, but I'm afraid that if I do, the PC will never recognize it again and lose everything. At least I haven't been actively accessing it outside of scanning/trying to copy. Going to have to look into the freezer trick tomorrow, even if I don't need it, I don't suppose it could hurt to know it's there, but I don't think I have any bags right now anyway.

Only do the freezer trick if you can't get the files you need without it since the drive tends to get condensation on it while thawing out which is generally a bad thing and only meant as a last resort. Lucky for you there are a lot of external drives on sale.

Also while I know this seems obvious now, keep anything important in at least two places. Online backups or multiple backup disks are easy to setup. Disaster recovery is much easier if you already have a second copy of everything.

Just had a weird thing happen and was wondering if anyone can explain it. I have my home PC set to automatically recover in the event of a power loss as I run a couple of things off it. We had a power cut today that knocked out the power for about 45 minutes, but the PC didn't come back up. When I got home I tried powering it on at the button - no joy. Did the normal stuff - checked the surge protector, fuse in the plug, etc, all okay.

Opened up the case, saw two green lights on the graphics card. Okay, cool, it's getting power. Check the power switch is okay and try shorting the pins, still no joy. Starting to get nervous about a fried mobo. Pull the power again, preparing to pull the thing out - and the two green lights on the graphics card stay on. Hmm, odd, some sort of capacitor discharge? Wander off for ten minutes to ring my friend to ask if he had a spare mobo, come back - lights still on. Okay, that's weird.

Pull the power connectors from the graphics card - and the LEDs go red. Huh. So that's what they're for. But where the gently caress is it getting the power from to light them up? On a hunch I pull the only other thing connected to anything with power - a powered USB hub I use mostly for charging things - and the PC instantly powers on.

I'm *guessing* that the USB hub is just running a common 5v rail and that was providing enough power to the bus on the PSU to light up those LEDs but not much else, but I don't understand how that can stop the rest of it from powering on - surely the CMOS isn't powered off of that same rail and so was thinking there was power?

I've had power interruptions before with this hub in and it's not been a problem, so I guess my main concern is whether something is seriously amiss with something on my PC?

(Not such a short question I know but it definitely doesn't deserve it's own thread - I've left the hub pulled for now to continue on charging duties and it's no great concern if I never use it again, but obviously if it's a possible indicator of future PSU or motherboard problems it'd be nice to know)

Really cheap USB powered hubs will push power into the PC even though they're not supposed to. This can cause issues with the motherboard and because of weird problems with a couple of PCs, I've replaced all of my cheap powered hubs with better ones. You can either open up the powered hub and cut the traces for 5v and ground to the PC, letting the onboard power handle all of the devices, cut the power and ground wires in the cable that goes from the hub to the PC, or get a better USB hub. I've come to like the Monoprice ones which are also sold as "Plugable" brand on amazon, they haven't given me any trouble. They do cost a bit more than the cheap ones, though.

All of the drive scanning and stuff you were doing to the drive was causing more damage. If it mounts at all just use roadkil's to try to get data off of it. Just being powered on is likely destroying sectors so you have a limited window to recover anything. You can try the freezer trick but don't expect miracles, sometimes it can just let you get 10-20 minutes of mostly good copies after 12 hours of freezer time which is a pretty bad ratio.

If you want to see if your disks are failing take a look at them with CrystalDiskInfo. It allows you to view the SMART data on them and see if there are any bad sectors or other problems the drives are having:

Ok, my hard drive issues are getting weird.

For reference here, I'm using an external enclosure to test these drives.

So far I've tested all but one drive, and all of them failed during the backup. Windows says they're corrupt and failed but the SMART stats say they're fine. The first drive I tested has Caution on its CrystalDiskInfo for Pending Sector Count and its Reallocated Sectors so I guess that's trash but the other two are Healthy and fine on both and work again after I format them, then fail during the backup process.

Am I missing something here? I kinda think maybe the enclosure is at fault, at least for the last two drives, but I can't really test the drives yet. It doesn't make a lot of sense to me that these drives would keep failing so quickly but stay 'Healthy' on CrystalDiskInfo. They are old, and if all of them were failing just because of a natural lifespan issue I'd understand, but they're entirely unused. Any ideas?

You're probably right, it sounds like the enclosure to me, too. The only way to be sure would be to connect them inside the PC or with another enclosure.

A power connector to a hard drive sparked and melted on me. Now it looks like two bronze columns on the side have black gunk on them and the next two seem to be missing. Haven't had any problems with the PSU on anything else.

I have some data that I've collected over the years on the drive, but I'm not going to spend money on it. Should I try hooking it up again or would that be too risky?

It probably depends if the short circuit was caused by the plug from the PSU or the connector on the HD. It sounds like it's probably the HD side of it, in which case it's likely to happen again. I wouldn't hook it back up to my PC for fear of it possibly killing the whole machine but there are relatively inexpensive USB adapters for hard drives that include power supplies and a molex connector. One of those would be less expensive to risk:

You're probably not going to have much luck if you're not willing to spend money, however. For example, if I was in your situation and needed the data back I'd buy a hard disk of the exact same model and try to exchange the controller boards. It would still be iffy, however. If it was valuable data I'd send it to a data recovery place, which get very expensive very fast, but they would probably do what I just described or possibly move the platters to a transplant drive just to get the data copied off in a clean room environment.

Thanks a lot for the advice. I'll order one of the adapters and see what happens. A friend of mine's pc just died, so I can also test the drive on that first.


For SATA cables, does it matter if neither of the ends have a 90 degree curve? It's a pain in the rear end, but they're the only ones I can find in nearby stores.

Not really, that's pretty normal. Most of the time if you need angled ends they're for sideways facing drive cages where you might bump against the case side with one sticking straight out. It's pretty common to get both straight ends or one angled end.

I bought one of these with the intention of using it with my monitor so I can turn it on and off with the remote. Will interrupting the power like that a couple of times a day be bad for the monitor/cause it to break?

I doubt it will cause any harm. Monitors are fancier than they used to be but they're still pretty much dumb devices. The main issue with yanking power from a computer itself is unsaved data and possible corruption of things that were in-use on the disk. Monitors don't really have that problem.

Any recommendations for UPS's? I'm looking for something to put behind my PCs so they don't hardboot whenever the power blinks. If I happen to be sitting right there when the power goes out I want to be able to shut them down gracefully, but I don't plan on actually using them off battery power for any great length of time. Any well-received brands/models I can be on the lookout for?

Cyberpower, Tripp-Lite, and APC are pretty good. I've got 4 Cyberpower units, an APC and a couple of Belkins (they're awful).

The main things to look at when buying one is getting one with sine-wave output so that it works well with modern computer power supplies. There have been a few posts about it that I can't seem to find, but the basic rule with UPSes and modern computer equipment is to either get a sine-wave unit or get a unit that can handle at least twice the power draw of the equipment hooked up to it. The other thing is that the rated volt-amps (VA) that gets listed on the UPS is never the same as the amount of Watts it can handle, despite the fact that Watts = Amperes * Volts. There should be a separate listing for estimated power output in watts on the product page.

For my main PCs I use 1000VA and 1200VA cyberpower units. For the NAS and networking equipment I'm using 685VA units. The big ones are 8 and 11 years old and I replace the batteries every 2-3 years. The smaller ones are newer. They all have AVR (Automatic Voltage Regulation, it steps low power up as well as just being a battery backup). If I had to buy a new one I'd likely get:
http://www.amazon.com/CyberPower-CP1000PFCLCD-Sinewave-Compatible-Mini-Tower/dp/B00429N192/
in whatever size seemed appropriate. Definitely shop around because there are often sales on UPSes. Look for free shipping or buy at a store also because they're really heavy because of the lead in the batteries.

They're sold in consumer electronics stores like best buy but also office supply stores like Staples which usually have good deals on shipping and often $ off $amount coupons and the like.

However before I can get a new graphics card I will be using a really old 6870 for a while. This card is inefficient and draws about 250W at load compared to 150W. Calculated the wattage requirements (90W for CPU + 50W + 250W GPU) x 1.2 = 468W, which is above the 450W limit. Do you think it would be okay for me to go over the maximum load?

It's not okay to try to get your PSU to supply more power than it's rated for. I'd get a 500 or 550 80+ gold rated just to be sure.

Friend is having problems with his laptop. Here is his CDI.



It was at 4 sectors last night. Then when I looked at it last night after I told him to run it it was at 5 sectors. I ran a chkdsk c: /f on it and when it was done it went back down to 2 sectors on pending.

https://kb.acronis.com/content/9133

quote:

Current Pending Sector Count S.M.A.R.T. parameter is a critical parameter and indicates the current count of unstable sectors (waiting for remapping). The raw value of this attribute indicates the total number of sectors waiting for remapping. Later, when some of these sectors are read successfully, the value is decreased. If errors still occur when reading some sector, the hard drive will try to restore the data, transfer it to the reserved disk area (spare area) and mark this sector as remapped.

Basically the disk has bad sectors that are being remapped. If the number's increasing then going back down it's getting more bad sectors and remapping them to reserved extra space that exists on the disk just for that. Beccause it's getting more of them it's likely that the disk is dying and the controller is attempting to save it by remapping, but it's probably not going to get better without a disk replacement.

I don't know how much he uses the laptop but with only 734 hours on the disk it might be pretty new and should be under warranty if so. If he can afford it, it may be worth replacing with an SSD since you're going to be taking the disk out anyway.

It's new, he bought it brand new in box from Lenovo's outlet store. It's only a few months old. From what I gathered from Lenovo's site it did come with a 1yr warranty since it was still BNIB.

I'd definitely contact them about replacement, then, the disk is going bad. If they won't do it western digital might, they have a warranty checker online.

I asked this in the PC Part Building thread, hope it is OK here.

What is the best way to ground yourself when changing parts? I heard that plugging in the PSU that is off at the socket and switch and putting and attaching a wristband onto it is the best bet but I really don't feel safe. Are there any other options?

The basic rule is to touch a grounded thing every so often, usually before you touch a static sensitive thing. A power supply that's plugged in but not turned on is grounded (the housing literally has a wire that goes to the ground from your outlet and isn't controlled by the switch), so it's a good choice. Plumbing in your house is usually also grounded so you might be able to touch a metal faucet as well, assuming you have copper pipes (I don't know anything about plumbing but the faucets here give me a shock if I've been walking around in fleece). You can wear a wrist strap if you want but I usually go by this checklist:
1) don't wear fleece or other material that build up static really fast, I usually go with jeans and a t-shirt for computer building.
2) touch a grounded thing before I touch computer guts (basically before I put in the CPU, RAM, and mount the motherboard inside the case, or pick up my video card I touch a grounded thing each time)

I have an ESD strap but I rarely use it unless I'm doing something that's really sensitive or expensive. If you're really concerned about static get a wrist strap and wear it, it will just be always attached to the ground in an outlet like the housing of a power supply will be. Static damage can be really bad but the only time I've had something die to static that I can recall was putting token ring cards into pentium 133 machines as a summer job. They didn't give us wrist straps but they had to have a motherboard exchanged because the system was just DOA after putting the network card in. I think it was in 1996.

Fair enough. I have to admit even though it'd be off at the PSU/plug socket, the idea of attaching a wristband to the PSU/case while something is connected to the mains (which is a higher voltage in the UK) makes me a little uneasy.

You can touch a grounded thing or a ground wire all day, it just goes into the ground/earth. The housing of the PSU connects to the metal on your computer case which is also in theory grounded because of it. The thing to do is to not touch the powered lines, but you don't have access to those from the outside of the housing unless you're messing with the plug itself.

So potentially having the the PSU plugged in, while being off at the plug socket while also being off at the PSU itself and having the wrist strap attached to a bare metal case screw is safe enough?

Yeah but I'd attach it to the PSU if you can because the screws into the housing from the case don't always break all the paint/powdercoat on the PSU. Does your ESD strap have an alligator clip or a ring thing or what?

Alligator Clip

My wrist strap is also one of those and when I use it I just clip it onto the grate of a plugged in power supply or into the middle hole of a computer power cord (do the former, not the latter). You're just grounding out static not sending high voltage anywhere and while the PSU is off there won't be any live voltage unless you open it up and specifically look for wires to short or capacitors to gently caress with. It's hard to mess up grounding yourself unless you go looking to do so.

Is mixing two different speeds of RAM a no no? I received 8 gb (2x4) g skill ripjaws ddr3-1600 and another set of 8gb ripjaws ddr3-1833 . If I can use both (even if limited by the slower set) I will, but not sure if that's advisable

Most memory controllers will be happy to run all that ram at 1600. Just put the 1600 in one channel and the 1866 in the other.

Based on a recommendation in the Parts Picker thread, I picked up an ASUS GTX 970 today. Specifically this model:

http://www.asus.com/us/Graphics_Cards/STRIXGTX980DC2OC4GD5/

After a bit of twisting to get it into my case (Antec Lanboy), it still doesn't seem to fit properly. It slides into the slot properly, and the latch engages, but the screwholes on the backplate don't line up with those in the chassis. Like, the card is seated properly, but I can't get the screws in. Any ideas? Seems like I could bend the backplate, possibly, but I'm not about to do that. It's almost like the card needs an extra couple mm in that direction to line up with my case's backplate.

I mean the thing works, I'm using it right now. But I'm going to need to actually screw it in before long; I have my case lying horizontally at the moment.

Also, the fans aren't turning, even though I certainly plugged the power cable into the cooling unit. Do the fans just not turn at a light load, or do I need to check the power connection? I can't seem to find an 8 pin PCI Express power connector, but I have a 6+2. Is that the right one?

I've had this happen on occasion and every time I was usually able to get it to go with a little force. I don't have that specific case so it's if really bad, this may not be sound advice. Obviously you don't want the card pulling forward out of the pci-e slot or anything, so you may need to loosen the motherboard mounting screws slightly and shift the whole thing back for a tiny amount of extra play. You definitely want the thing to be attached to the case since it's so heavy, it will need the support.

On that model the fans don't turn on until the card gets under load, usually in 3d applications. It's a feature! The PCI-E 6+2 cable is the same as the 8 pin when you attach the 2 to the 6, so you should be set there.

I have an Antec P180 tower, and just bought a new 3.5" HDD. However I seem to have misplaced the HDD mounting screws the case specifically uses (they're shouldered screws, half-threaded, with large flat heads), and can't seem to find an exact alternative via Antec's site nor anywhere else. What's my best option here to get my new HDD installed securely?

I'd contact Antec support, they may send you some for free.
There's a picture of them in this thread:

It looks like you want the big ones in the middle. I couldn't find any shouldered 6/32 9/16" screws online that looked like the ones from the pictures, unfortunately.

There is a box inside the case that the mounting hardware came in, could you have put the extras back in there? There's a picture in the review of the case:
