anyone know what problem this could be? I searched yahoo, and it seems that it could be power or motherboard. I dont think it is power. Before i turn in for the night i shut my computer down, and then when i wake i turn it on.

Now this is when i have trouble, it turns on for like 10-15mintues but then shuts down. Then when i use say like macromedia it turns off more often, and at times could just be random when i'm just surfing the net.

When i try and turn it back on, it trys to start but shuts down. The best way to describe this is like trying to start a car. It trys to start and shuts down, and i try and start it about 4-5 times and it does the same. I wait like a full mintue and try again and it works.

I doubt its a virus b/c i have it on guard 24/7 and scans regularly. Any idea? And if it is the motherboard should i start saving my important files and documents on an external harddrive? I'm not that computer literate, so any advice i do appreciate.
