Randomly BSODing

[ganning59]

I have just recieved my computer back from Geek Squad, I was experiencing massive BSODs, they replaced the hard drive and said it was fixed. Now I'm getting only one BSOD and it's random, PFN LIST CORRUPT. How can I fix this? I have an ATI Radeon 6850 HD video card, with it I was fine for a month then the errors started.

I'm really frustrated, so any assistance is greatly appreciated. I have the two latest dump files if it's any help.

Blue screens are normally either caused by faulty memory or faulty drivers (particularly video drivers). I suggest that you try running a memory test program such as memtest86 overnight to eliminate the memory being the cause of the problem. Once you have eliminated the memory as being the cause of the problem then try disabling drivers or updating drivers or in the case of the video driver trying older versions of the driver by either rolling back your drivers or downloading old drivers.

Good advice pjmelect. The PFN List is the Page Frame Number database that the OS uses to track of the allocations of physical memory pages.
