Have you installed any hardware, or updated any drivers lately? Perhaps you
could try a system restore point. Also, you might want to test your memory
to make sure it isn't the fault. Windows Vista has a memory testing program.
Try the memory diagnostics tool. Type "memory" in the start search box to
find it. It will require a restart.
