My computer crashes when I'm in a game, lets say League of Legends or Unreal Tournament 2004. My trash computer keeps freezing then shutting off/rebooting on me. All I have running is Windows Media Player along with the game nearly all the time if I plan to game.

Windows XP 32-bit
Pentium 4 3.2GHz (Only has 1 core, OC'd to 3.5GHz)
2GB RAM (OC'd to 438MHz, from 400MHz)
Intel D875PBZ Motherboard
GeForce 7600GT (512MB, AGP 8x)

Why? This happens on average about twice, maybe once a day if I plan to game. It is worth pointing out that it has crashed three times in one day while trying to game... Why? I have a feeling something is going wrong when my system is stressed hard. Please advise, thank you.

Well... if the problem occurs when you are heavily stressing your system its because either your CPU or GPU are overheating or your PSU is failing and it cant provide enough wattage to keep your system running

PSU - Ultra LSP 750W...

I really do understand that my system is outdated pretty badly. I've been searching for a decent used system so I can hold over until IB-E or Haswell/Broadwell comes out, but in the end I've basically had no avail. For now, I'm content with what my system yields. As for my CPU's thermal compound, I replaced it not too long ago so it should be holding up.

Why I have Windows Media Player up while playing games is because I want to play music while I game -> That's to the person towards the top of this thread.

Overheating issues -> Not really. I checked my CPU temperature in game a little while before the computer crashed, and the highest I had seen was 52°C(this was literately a bit ago before this reply was posted). That's not that bad... Right?

Here's some new information. I finally acknowledged this Windows error message that comes up after my crashes...

Because its the only thing left to rull out, we know the problem isnt overheating nor is thermal paste, and i highly doubt your CPU is damanged so it must be the PSU.

agreed... your psu could be faulty and sending too many watts, and when the computer senses this, it shuts down to save its self

hmmm.... i think its actually the oposite, my best guess is that the PSUs transformer is damanged so it cant produce wattage (and ampers) requiered for PC to function
