Crash Without BSOD

Xelvanox · May 31, 2016

Sorry if this has been posted before, it's actually difficult to find anyone with this specific problem. I have a desktop just built a few months ago that hadn't had any noticeable problems. The other day, it turned off without warning, no BSOD or anything. My case light and fans came on after a few seconds, but there was no power or signal to my peripherals or monitor. This occurred even after power cycling several times, and the computer refused to boot for about five minutes. Afterward, the same thing happened a few hours later, and again the next day.

I ran MSI afterburner to log the CPU and GPU temperatures before the second crash, and there was no overheating. Memtest 86 didn't show any RAM issues. At this point, I assumed the power supply was overheating, but the PSU fan was running and there was no dust or physical airflow blocking.

I feel like the issue is a broken power supply, but before I go spend anything else I wanted to see if anyone else has had this issue, and potentially a solution.

Thanks in advance.

Remove the power supply, and do the paper clip test.

If it shuts off within 5 minutes, its busted.

If you need a new one, get a REFURB AX760 form Newegg, like $90 and may aswell be brand new with he condition they come in.

It sounds like it could be the PSU, mobo, or RAM, but based on the fact your RAM passed, I think the RAM is probably fine, and since it didn't crash while testing, it's probably not the mobo either.

Thanks for the quick response, I'll try testing it tomorrow.

Status report: Paper clip test ran for 10 minutes straight before I pulled the power, if it's the problem piece the issue is intermittent. My best guess is the motherboard, but I'm at a loss for any way to confirm this.

At this point if you have no spare PSU I would test the PC without the GPU just to see.

When troubleshooting those kind of problems the key is spare parts. Try to see if a friend has a PSU you borrow or even try your PSU on another similar build.
