Windows 7: Bsod - pfn list corrupt

16 Oct 2012   #1

Windows 7 Home Premium 64bit.
Bsod - pfn list corrupt

I've had this computer for about 6 months now. I've had BSOD constantly, and whatever I do isn't helping a friend told me to come here. So here I am, if you can please help me.

I've run Prime95 for 24-48 hours and no problems then I can run it a different time and it will crash. I've fixed my other problems with people for others but this has got me stumped.

I keep getting PFN LIST CORRUPT.
I've uploaded my dmp files, the one's in the Zip called minidump and minidump2 are really old dmp file's, I thought they might help so I've included them.

They usual happen when my computer is idle (when i'm away from it), I normal have games running. Maybe about 15-25% of the time I get a BSOD while gaming/working/browsing.

I've kept my drivers up to date. I've overclocked and kept it default still nothing.

Looks like older drivers of Magic ISO SCSI Host Controller are causing it.

Either uninstall or get the latest drivers for it.
(un-installation is a better option)
