Hardware is one of the causes of this error and I have seen bad RAM cause such behavior.

Thus my first suggestion is to run Memtest on your memory.

See link: http://www.techspot.com/vb/topic62524.html

Let it run for a LONG time. The rule is a minimum of 7 Passes. There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.

If you have errors you have corrupted memory and it needs to be replaced.

Also, with errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.
