Problem out of no where

[One43637]

the oddest thing happened this morning. i left my computer on overnight and when i woke up the next morning it was shut off. i tried pressing the power button and the blue light on my fan controller lit up briefly then died. i repeated the process and was greeted with the same result.

my room is well ventilated and my cover is off the side of my case because i was showing someone the cabling job i did. i built this machine early this year, around February or March and have not experienced any problems. I'm puzzled what could have went wrong. my initial reaction was the motherboard , but is there anything else that could have went wrong that i could check first?

Do you have any pets or kids running around? Strange things can happen to unatended machines,gremlins are everywhere. A friend once went to ride his bike after sitting through the winter & it wouldn't start. He took it to a shop & when the mechanic got it started it blew puppy chow all over the guys shop. Mice.

Sounds like the PSU took a dive... either that or something got fried from ocing (most likely mobo, even with the a8n32). See if you can pick up a cheap psu tester at a local tech store. Other than that, all you can do is try booting with minimal hardware, and/or try switching out hardware with extras to see what failed. Don't forget to try resetting the bios too (worth a try).

99% PSU. Maybe a surge at night.

thanks for the replies. i'm hoping it's just a PSU and not a motherboard because of the extra work involved. it's odd since i had an older machine that was Folding on the same outlet, different surge protectors that didn't go down.

i thought i considered my OC mild seeing as i went from a stock of 2.2 to just 2.4, but an OC is an OC =/

thanks again, i'll have to find a PSU tester somewhere in my area or hopefully just take it back to the place i bought the PSU.
