Help! computer keeps shutting down!

[TannakaObi]

Can anyone tell me why my computer keeps turning itself off. Normally while I'm on games or other media programs.

nothing happens, no messeges or anything. Someone told me it could be my power cable. I doubt it as I can stay on for hours at a time, even days if I'm on the net or useing photoshop, but as soon as I do somthing like play world of warcraft it just shuts down!

M&P
Medi-power el ectronics,

I've never seen anyone tell us the information on their power cable, and because of that I'll help you!

Answer these questions.

1. What are you doing when it shuts down?
2. What are the PC temperatures?
3. Is the PC case very dusty?

Bad power supply, heat and bad RAM are the most likely suspects. Is that the original power supply? How old, and what is the make and wattage.

Take the side off and blow a fan directly in there while gaming.
