PFN_LIST_CORRUPT Error

Hey all,
Lately I have been getting a lot of BSOD's containing the "PFN_LIST_CORRUPT" error. I understand that this error has something to do with memory, but I may need some clarification. Also, if any one knows of a way to resolve this issue, it would be much appreciated.
I am running:
Asus P5WD2 E-Premium
Intel Pentium D805 (no overclock)
2 Gbs of Ram
Nvidia Geforce 7900 GT

Thanks

You can use free downloads: Belarc Advisor, Everest, or CPU-Z / CPUID to run an inventory of your computer, in order to start the fix. It is usually a Windows 2000 error, and is rare in WXP. Which OS do you have? It is usually a driver error, but figgering out where is difficult.

SYMPTOMS
When you use a Windows 2000-based computer, you may receive the following error message on a blue screen:
STOP: 0x0000004E PFN_LIST_CORRUPT (Parameter1, Parameter2, Parameter3, Parameter4)

This behavior occurs because a driver or other problem damaged the input/output (I/O) driver structures. To troubleshoot this behavior:
1. Run hardware diagnostic tools that are provided by your computer manufacturer.
2. Disable all file system filter drivers, such as backup utilities, virus scanners, or firewall software.
3. View the following Microsoft Web site to verify that the hardware and the drivers for the hardware are compatible with Windows 2000:
http://www.microsoft.com/whdc/hcl/default.mspx (http://www.microsoft.com/whdc/hcl/default.mspx)
For information about the hardware on your computer, contact the manufacturer.
4. If you receive this error message randomly, or when you try to start a program, remove extra memory or have the random access memory (RAM) in your computer tested. This behavior may occur if you have bad RAM.

Yea, I have googled the error, and tried what Microsoft says. None of it worked. Although the last link gave the different types of that specific error, and by looking at the event viewer, I narrowed it down to 0x8F. According to that page, it means "The free or zeroed page listhead is corrupt." Whatever that means >.< Oh, and I also have ran Driver Verifier, it didn't find anything :[ Anything else I can do?
