So I bought a bunch of computer parts and built my own machine for gaming, and up until this morning it's been incredible. The problem started sometime last night when i went to bed, it was turned off. I didn't turn it off, so I figured my mom did for some reason.
I turn it on and everything is fine as i do random shit for a bout an hour or two. I launch tf2, and after it's on for about 10 minutes, my computer justs shuts off. It's like I restarted it, the computer shuts down but before the fans stop spinning, the fans spin up again and the computer gets up to where it says "windows is starting up" then it will turn off again, it continues to go through this cycle of fans spinning up until i turn off the power supply. Once I turn the power supply back on, windows starts fine and it'll be good until i start a game and play it for a couple minutes.
I've checked all of the cables and parts, nothing seemed to be loose. I downloaded a temp monitor software and watched it as a game ran in the background, the temps were normal.
