Alright, I need some serious help with this
I bought this computer about 2 and a half years ago, ever since I bought it it presented a problem: Overheating. I got it fixed a couple times and it worked fine, though they never told me exactly what was wrong. Then a couple of months ago it started overheating wherever I wanted to play something, even a GBA emulator made it overheat(though it could stay on for days if there wasn`t anything "heavy" runing). The return of the problem made me send it to the place I sent it last time(and where they managed to fix it), but the guy there told me he couldn`t find any problems and sent me the computer back. Now, behold, the computer came back WORSE than before. It just turns off after a few minutes, it doesn`t even overheat before turning out now. I already tried replacing the power suply(originarilly 450, now 500) and it`s still the same. I`m totally lost, as the cooler seems to be working fine. Please help me.
