Frequent BSODs - 30 to 60 minutes apart

Windows 7 . . .
- x64
- original installed OS on the system
- full retail version

- age of system (hardware) is almost one year (custom built Nov 2009)
- age of OS installation is same as hardware (OS not re-installed)

Everything has been working well for almost a year. Starting about three days ago, my system will barely stay available for 30-60 minutes at a time

I get PFN_LIST_CORRUPT, MEMORY_MANAGEMENT, PAGE_FAULT_IN_NONPAGED_AREA and IRQL_NOT_LESS_OR_EQUAL BSODs and cannot pinpoint the problem.

Have already tried SFC /SCANNOW.

Please help!!!

Yup, although the dump isn't entirely helpful. It appears that there is some corruption in the dump, likely by a driver, but the dump did not capture the failure, only the corruption after the fact. Please enable driver verifier, and get us another dump.

According to the latest dump, you had a processor error:

If you enable verifier and you bugcheck, I think you may be right. It's probably useful to do a memtest, Prime95, and FurMark stress tests to verify your hardware really is not showing an issue that could be causing these, but if those pass, you're going to need to take a close look at what you've got installed that would have boot-critical drivers other than the OS itself.
