Why does my computer locks up at any given time?

Since building my computer over a year ago, it has continuously locked up. I have checked the temperature. It is usually around 16-18 degrees Celsius. There are no viruses on my system. It can lock up at any time, without warning, on any application that I run. It has even locked up while shutting down, starting up, playing a game, sitting still, while on the internet, and on a Windows sceensaver. The lockups are always hard lockups - not able to be solved with Ctrl + Alt + Delete. I have to press the reset or power button. It has this problem on both Windows 96 SE and on Windows XP. Before a lockup, I recieve no warning. The computer gives no warning sounds or mouse catches. My computer has also been known to go for days without locking up and then lock up several times in a row. Once I clocked it to lock up 20 times in two hours.

You appear to have a power supply problem If possible check the voltages with a multimeter or have a professional repair technician evaluate it If that is OK, then you have a bad motherboard.
