BSOD this morning

just had a BSOD with message: PFN list corrupt.The blue screen came as I just rightclicked on the desktop (empty area). Don't know if it's related to CoreForce driver. CF was unloaded as it happened. That's what I got from my event viewer, no minidump was to be found where it should have:
