It'd be good to post your specs at this point. Disconnect all non-essential peripherals and try using onboard video (if you have it). If that doesn't work try using only one stick of RAM.

Anonymous Robot posted:I tried doing this, and it didn't change matters. I've since also tried connecting the HDD to an AC-to-SATA power adapter, and it still didn't boot. I tried changing out the data cable and MB port. I'd be totally ready to call this a case of dead HDD, get a new HDD and move on, if it weren't for the fact that my front intake fan also isn't powering, which just vexes me. From everything you've posted it's possible that the old PSU killed the fan and HDD and using a new PSU isn't going to revive them (but it's just speculation at this point). Using the adapter did the HD start spinning or is it not even moving? If it's moving I'd try to connect it to another computer if possible. How old are the fan/HDD? If the computer POSTs and the fan is the only thing not work then the fan is probably dead.

Anonymous Robot posted:The HDD does not move when connected to AC power. The computer POSTs and is fully functional; my OS is stored on a functioning SSD. The thing that confuses me is, if the old PSU was bad- which is likely, as it was old and my PC was occasionally powering off, hence getting a new one- why didn't the HDD die before, rather than concurrently with switching over to a new one? That makes me think the new one may be bad. The HDD is probably dead if it's not spinning while plugged in. One possibility is that shutting off the computer triggered the failure during the upgrade. It's not uncommon for a component to fail during an upgrade process. There are many different power states and sometimes when an older component is shut off fully it won't turn back on: https://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface Sometimes a computer/PSU will be operating fine and then someone moves it to another room and it won't turn back on. The computer being in a fully mechanical off state is enough to kill it. If you want a crude analogy this is why doctors hesitate to do surgeries on elderly patients. Many older people put under sedation never wake up. Or it could've been a coincidence.
