Computer Randomly Died

[zcalpey]

Hey all,

I built a PC maybe 2/3 years ago and it has worked flawlessly. Today I was playing a game, and my computer crashed, which is something that rarely happens but I wasn’t worried. I reset the PC, and it worked fine. Anyways, I went to do some other stuff and came back. My PC had gone to sleep, and I hit the power button to turn it back on... nothing. I tried hitting reset, unplugging power, resetting the power supply and all leads to nothing. Whenever I “turn on” my computer all that happens is the power LED turns on, but none of the fans or other systems start up. I tried unplugging/replugging the power/reset on the motherboard, but got the same result. Not sure what to do. I was thinking about trying to reseat my CPU to see if that does anything, but I figured I’d get others opinions first. Any help is appreciated.

thanks

Maybe a PSU problem? Do you see any led lit up on your motherboard?

My motherboard has no LEDs unfortunately.. would it be a PSU problem even if the power LED on the case is lighting up?

Ok so a led lits up, that is a good thing! Do you hear any fans spinning while powering on the computer?

No fans spin. Sounds like the hard drive might start to spin but it’s a dull sound and hard to tell.

Maybe a 12V rail on the PSU died! Do you have any other PSU to test?

sadly no. Any other way I can test for it?

Not really! Can you lend a PSU from a friend or old computer laying around?

I found a test that Seasonic had on their website that involved shorting out the motherboard pin with a paper clip. Anyways, the fan is spinning, so supposedly that means the power supply is good?

 

edit: I plugged the cables all back in and powered it on and it surprisingly worked. Hopefully it doesn’t happen again. Thanks for your help!

Dust can be a problem if your PSU fan is facing up. Dust fall into it, that actually cause issues.
It actually did for my mini ITX system. It died randomly, repeatedly. I cleaned it with my CompuCleaner Xpert ( you can do it with dry air bomb ), and it never had any issues anymore. I'm just a bit more careful now with dust with mini ITX.
