Computer Problems

[Guest]

My computer is acting really wierd lately. It randomly shuts down by itself. I have no reason why, and was wondering if anyone could help me. I run windows XP and the computer itself is only about 3 years old. I've tried cleaning it extensively but it had no effect. If anyone has any input, it would be greatly appreciated, thanks.

Well it is always difficult to find causes for such funny features.
You can have some well-known problems here:

Faulty power switch or faulty power supply is highly possible as FDIV says.

The last time I had this problem the culprit turned out to be a faulty power switch that intermittently shorted out. The computer also randomly turned itself on though.
