!!! smp client causes BSOD please help

I usually use just the GPU feature of the tracker, and only recently decided to also begin work on the CPU client as well. However, after starting the SMP service, my system would BSOD (blue screen of death) every few hours. The error code is 'PFN-LIST CORRUPT", which is a memory error. On debugging the dump file, Windows Debugger seems to think it was core_a4.exe which was causing the problem. I had reset my CPU clock to default, but the problem was not fixed. Does anyone else have the same problem? How can I fix it? Thanks a lot!

I am using a Intel i5 760 @ 2.8 ghz

Below is the debug report for my latest dump file:

PFN_LIST_CORRUPT (4e)
Typically caused by drivers passing bad memory descriptor lists (ie: calling
MmUnlockPages twice with the same list, etc).  If a kernel debugger is
available get the stack trace.
Arguments:
Arg1: 0000000000000007, A driver has unlocked a page more times than it locked it
Arg2: 000000000011d971, page frame number
Arg3: 0000000000000001, current share count
Arg4: 0000000000000000, 0
