BSOD: page_fault_in_nonpaged_area

Long time no see guys! I have come across a problem that I cant diagnose myself so I figured I'd stop by, say hi, and get you guys to help me out lol

I recently started getting random BSODs at really odd times. The system was never under load, usually just surfing the net or something. They are usually dealing with drivers but this latest one was different:
page_fault_in_nonpaged_area (sorry I didnt get the "stop:" code )

I searched around online a bit and cfound that this is sometimes a RAM error but my RAM is a relatively new OCZ 2gig set that has been working flawlessly since I put it in. I had a long stint with overclocking and this RAM has seen it's share of stress tests and it never stumbled or anything so I think I can rule that out.

I checked the minidump folder and I have 2 DMP files in there, one from yesterday and another from october 2008 lol. I'll attach the most recent one.

Another thing that concerns me is when I checked the event viewer, it shows that one of my hard drives keeps having errors, but I dont know which one it is. I have a newish seagate 7200.10 250gig and an older WD 200gig. This would make sense because that could be affecting the page file and giving me the BSOD.

This place used to be my home away from home so I'm hoping you guys still have the magic touch Thanks in advance

Current setup:
ASUS P4P800-E Deluxe
3.0 P4
Audigy 2
2gig OCZ pc3200
XFX 7900GS AGP
Seagate 250gig 7200.10
Western Digital "caviar" 200gig
OCZ 700W PSU

Start with chkdsk c:/r first as "one of my hard drives keeps having errors" , then pull RAM one module at a time, and last the graphics card. "Faulty hardware, a buggy system service, antivirus software, and a corrupted NTFS volume can all generate this type of error." TechNet.

 

The thing is, it only happens once in a blue moon, so I'd have to run with one stick of RAM for a while before anything happens. Also, this is my THIRD XFX card (first a 6800XTreme, then 2 7900GS's) that this has happened throughout the life of so if it's anything I'm going to vote for RAM or one of my HDDs. I'll run check disc and report back. I'll run memtest as well, maybe that will show me something with the RAM
