Solution 2 - Check Memory 

Both Windows7 and Vista includes memory test program when booting from the Windows DVD.

or Download Free memory test software from : http://www.memtest.org

Burn it to black CD or make a bootable USBstick.Once booted it will test your memory. One full past will catch most errors, but you can let it run longer.

I would run it first to see if it finds any problems with either stick. If it does take one out and test on each stick individually.If only one stick tests bad then it's very likely the problem, but if both test bad ,or neither, then it's likely something else.

Solution 3 - Re install Windows

New installation if windows will insure that all drivers and hardware compatible errors are gone and everything will be back to normal.Please backup your date before formatting your windows.
