[SOLVED]Computer messed up. Need help.

My computer is very messed up. On Saturday, it started behaving like this. When my cousin was here, I talked to my cousin, and five minutes later my cousin tells me that my computer turned off by itself. I’m like WTF? and then I turn it on. After it boots, five minutes later it turns off by itself. No BSOD or other bullcrap. Just turns off like *POOF*. Can somebody help? I really need my computer because I have an important school project that is 65% of my grade. Any help will be highly appreciated. Thanks.
Answer #1
It could be a overheating problem (try removing one side of your PC case) or it could be a sort circuit problem, have you put any new hardware into your PC ?
Answer #2
I don’t really have enough info, to really help. Something like this happened to me few year ago, somehow my heatsink on my CPU came loose, and I had no idea why my comp was turning off by itsself, took me a week to release something was over heating, then I found out my heatsink was loose.
What I can help you out with, is open your side case, see if the fans are working and if anything is overheating.

As far as I know, the only hardware I installed into my PC recently was a new sound card. Problem started to happen ever since I installed it. I removed it and switched back to my old sound card, but the problem still persists. How do I know when my computer is overheating?

How do I know when my computer is overheating?
well my PC was just shutting down like yours a while back and it was because the processor fan was lose which coursed overheating (same as jonny), so you can just make sure everything is plugged in correctly and when its running make sure your HDD”s are not overheating (you can tell by just touching them, space them out if there hot)
and about the sound card i don’t think that is the problem because you sead the problem continued after you put your old one back in so just make sure all the power cables are plugged in correctly (not lose)

Thanks for all your help!
I fixed it by doing that and found out the problem was in the power cables.
Thanks you guys!
