you should test your memory to make sure that it has no error. Download the memtest from http://www.memtest86.com/ and boot off the CD or floppy. Then let it run for like 8 hours/overnight or longer to see if there's any error (usually if there's any big error, you should notice it in a pass or two, like a couple of hours).

If you have more than 1 stick, test 1 stick at a time. Also, you may need to test diff slots.

List your complete specs, it could be your psu as well or the mobo.
