On my last computer I was having it do the same thing. A lot of times it is the power supply that causes it. If you have added a lot of devices to it then it might not have enough power to run them all. Have you added anything new to it? Also the PS just might be going bad. That is what was wrong with mine. Good news is if it is the power supply they don't cost that much. About $50 would get you a 350 watt one, and for the average user that would more then likely be enough. But you might want to look into a 400 watt.

Anyway that is my guess on what the problem is. Let us know what you find out.
