Hi,
I constructed this device around two years ago and it has been functioning properly until two days ago. Usually it powers down after 15 minutes, but when I returned, the fans were running at full speed even though it shouldn’t have been idle. It wouldn’t wake up, so I used the front power button to power cycle it. At that stage, it wouldn’t POST.
I removed the CMOS battery for 5 to 10 minutes and then restarted. It booted back into BIOS, reset to defaults, and returned to work…
Today it worked fine until I rebooted again. I checked and found a BIOS update (F7 was the version I had; F10 is available). I installed that one, rebooted, reset to defaults, and went back to Windows for about ten minutes.
Then it crashed unexpectedly, refusing to POST. There were no keyboard lights or BIOS logo displayed. It’s the same as before.
I’ve tried these steps:
- BIOS update from F7 to F10 – worked briefly, then crashed and failed to boot
- Removed GPU, reset CMOS, switched to integrated graphics – still failed to POST
- Deleted RAM, failed to boot
- Disconnected the boot drive, failed to start
- Tested various RAM modules one by one

Any suggestions or parts that might need replacement?

I begin this here just for laughs. It won't go unnoticed, but the text is exactly as it seems.
Thank you, but the problem also includes it not booting from a USB stick.
Is this the final state? I'm getting mixed up because the system sometimes restarts and then stops working eventually. Psu is quite outdated, should I start there anyway? Let's see how it goes then, if it doesn't work, you've already covered that point. If not, maybe we should consider swapping the motherboard instead of a full overhaul.
Tested using a brand new PSU with memory and without memory, no changes in behavior. No beeps, no splash screen or any other issues. I’m considering if a new MoBo is necessary since I don’t have a collection of spare parts to test.
