After talking to father and brother techies, we decided the power supply was faulty. I replaced the power supply, and it then stayed on for 9+ hours. I then proceeded to pay for the computer game that I specifically bought the computer for, and 5 minuets into the game, it turns off again (it had been running for many hours before that point). It's a online subscription game, so I want to fix the problem ASAP.
I thought maybe the graphics card is causing an emergency shutdown, though I find it strange that replacing the power supply has allowed it to run when not playing games. All fans are running and heat sinks are dust free. I have tried to run the computer with a graphics card borrowed from my brother, but then the computer won't turn on at all. I am now running the computer without the graphics card driver to see what happens, but in the end I need to get it to play my expensive online game.
Thanks for any advice you can give.
