Have you recently installed any new hardware, software, or updates?

Try downloading the microsoft memory tester.

Run this tool to check for bad memory. If you have multiple sticks of memory, run the test on each stick individually.

I am heavyly leaning towards some drive conflict....

guess i will have to try things one at a time....
