Problem description: New win 10 system exhibits "mini freezes" where the system hangs every few seconds. The mouse cursor freezes, and any sound playing stutters. The system then fully corrects itself before locking up again a few seconds later. Sometimes system entirely locks up, although this is rare. Crystal mark drive analyser says drive is in good health. Left memtest running overnight, and it came back with no errors.

Attempted fixes: CHKDSK /f /r, full system wipe + OS reinstall. Updated BIOS to latest version.

Recent changes: New parts were installed two days ago (New cpu, motherboard and ram).

--

Operating system: Windows 10 Home

System specifications: i5-6600, ASRock Z170 Pro4, MSI Nvidia 970, 16 gigs DDR4 Corsair Vengeance LPX, Corsair 650W TX Series PSU, 1x Western Digital 2TB Caviar Black HD. No overclocking on any component.

Location: UK

I have Googled and read the FAQ: Yes

Yes, updated the BIOS to the latest version, and the problem still occurs.

Issue is particularly noticeable when watching a youtube video in a browser window, as the audio stutters quite regularly.

No one asked for it, but here's the Crystalmark:

These are the temps I got from both programs while using chrome to watch a YouTube video:

Doing the intel update thing just now.

The intel program doesn't seem to detect any drivers. I get "No drivers were detected for your product" when I click scan.

Edit: PSU is about 5-6 years old.

Went to the ASRock website and grabbed the latest chipset drivers. Problem still persists.

Installed all that stuff. Problem remains.

Gunder

I'm reluctant to start throwing money at the problem until I have an idea of what might be causing the problem. Is there a way I can test the PSU in order to rule it out as a problem?

Edit: By the way, thanks for helping me with this. I'd be lost without the advice!

New symptom has appeared: I can't get my new AOC G2460PG monitor to display anything on startup. It connects via DisplayPort, and doesn't have any other inputs, so I can't try hdmi or dvi. When I boot the system, it never wakes up from standby. The most it does now is display No Signal, before returning to standby if I turn it off and on again.

Edit: Amazingly, unplugging the monitor from power for a minute, and then reconnecting, seems to have restored the monitor.

I decided to install my old Xonar DX, to see if that would help with the sound issues and general stuttering. Miraculously, it seems to have fixed it. I've been using the system for about an hour, and haven't had any problems. (I uninstalled all the Realtek stuff) I'll continue testing this evening and see if this continues to work or not.


Edit: System seems to be fine since disabling the onboard Realtek sound.


Edit2: Days later, problem has returned.

Seems like the problem has returned.

The only change I made was to go into the BIOS and activate the XMP DRAM profile to try and make my ram run at its advertised speed. Upon rebooting, Windows starts to stutter again, as before it did before. So I shutdown and selected one of the slower JEDEC settings instead, but the problem remains. I don't understand what wrong I did to resurrect the issue, but it's definitely back. Any additional help would be greatly appreciated.

I just removed the graphics card, and am using onboard video, and the problem SEEMS to have gone, but i'll have to do more testing to find out if that's true or not. This card is a 970 that I used in my old system from a year ago. I wonder if it's suddenly broken since moving to the new system.

If the issue is truly gone that means either the video card has an issue or the PSU is being taxed less by using onboard video.

Yeah, i'm gonna test over the next few days, make sure it's totally gone. After that i'm going to swap in my room-mate's 970 (exact same model and manufacturer). If it starts messing up with his card too then i'll look at PSUs.


Edit: Also tried a linux live CD and it was totally fine (for the 20 minutes I tried it for).

Tried my roommates 970 in my system, and he tried my one in his. I instantly got the return of the stuttering, while his setup was totally fine. So I guess it's time to try out a new PSU. I'll be going for the 650 watt EVGA Supernova G2, as recommended in the part picking thread. This will replace my 6 year old Corsair TX650.

Gunder

Just installed the new PSU to no avail. The stuttering is still present. I guess RMA'ing the motherboard is the next step?

Gunder
May 22, 2003

I tried moving the graphics card to the other PCIe slot, and the problem seems to have gone. I'll test more over the next day.

Check the BIOS to see if there is a setting regarding PCIE frequency. I've had issues with the Nvidia 360.xx series drivers and setting the PCIE frequency to stock in the BIOS stabilized things for me. Also turn off hardware acceleration in your browsers.

It's just set to auto.

Try changing the frequency to the default, which I believe is 100mhz. This is anecdotal, but setting this on my motherboard almost eliminated the graphics driver issues I was having.

PCIe Link Speed is the closest setting my BIOS has to what you're describing. It gives me Auto, Gen 1, Gen 2 and Gen 3 as possible options. Nothing about 100mhz.

CaptainSarcastic posted:

You could try setting that to just gen 3 and see if it has any effect. You could also try doing a complete uninstall of the video drivers using DDU and install pre-360.xx release Nvidia drivers and see if the behavior stabilizes.

Fortunately (or unfortunately) my motherboard rma is looming, so I'm about to swap out the boards in a few minutes. I guess I'll check what it defaults to in the bios before I let it boot into Windows for the first time.

Just installed the new motherboard, and the stuttering is STILL present. Not sure what to attempt next. RMA RAM perhaps? I don't have any other DDR4 to hand, so I can't try simply swapping in new RAM.

The system as it currently is:

i5-6600
ASRock Z170 Pro4 (Replacement, original has been RMA'd)
MSI Nvidia 970
16 gigs DDR4 Corsair Vengeance LPX
EVGA Supernova G2 650 watt (New part, to replace suspected faulty older Corsair TX650)
1x Western Digital 2TB Caviar Black HD
ASUS Xonar DX Sound Card
No overclocking on any component.

Have you run at least a full pass of memtest on that RAM? I've usually used memtest86+, but if you haven't run memtest yet then I'd do so. Have you checked to make sure the RAM timings in the BIOS match up what the RAM is supposed to be? I'd also check the USB 3.0 drivers and maybe reinstall those.

I still suspect the Nvidia drivers since you did the GPU swap with your roommate, but checking the RAM is certainly a good idea.

Also, is there a setting in the BIOS to turn off the onboard video?

I left memtest running overnight (3-4 full passes) and it came back with zero errors. The ram timings are set to auto, and i'm not really sure how to change that other than trying XMP profiles (which, if you read a few posts up, resulted in the return of the issue after it went quiet for a few days). I'm going to try a pre-362.xx driver rollback just now.

You don't seem to be able to fully disable the onboard video in the bios, just tell the system which thing is the primary output.

Rebooted into Safe Mode, ran DDU, and then rebooted again and installed nvidia driver version 359.06 (Dated from mid-January). So far....no stutters. Will keep testing.

So far, so good. I've already played Overwatch and Total Warhammer with no issues. Also no Youtube stuttering. I'll keep testing.

3 days later, the stuttering hasn't returned. Still on the old drivers.

Been a little over 2 weeks since the driver rollback. Still no issues!

Problems have returned. No changes have been made to the system, with the exception of a few windows updates. The problem now is that the system will hard lock when doing mundane things like watching Netflix. I've decided to try RMAing the video card.

You've had bad luck.

When you did use onboard video were you getting that stuttering?

No stuttering with the onboard. Back to using the onboard just now.

I've just realised that I've probably wasted my time by doing the RMA because I forgot that I had already tried this out back in May:

This would seem to suggest that whatever the issue is, it's not with my graphics card. gently caress.

Yes, I'm still on the 2nd PSU and Motherboard. I'll try swapping out the ram next week.


Edit: And I'm still using the Xonar sound card.
