strac27, sorry but I am answering you from another person's PC without a Windows DeBugger to read your minidumps. However, here is some information that can be help:

As per auhma.org 0x50: PAGE_FAULT_IN_NONPAGED_AREA

Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card).


* Try this: Run memtest on your RAM for a minimum of 7 passes (8 tests per PASS); if you have any errors you have corrupted memory that must be replaced. Corrupted memory can cause all kinds of issues.

www.memtest.org

* Also, IRQL__NOT_LESS_OR_EQUAL errrors are due to either a faulty driver or buggy software. Perhaps someone will come along and be able to read your minidumps before I return home in a few days.

* Whatever, do the memtest first and report back what you find. Keep in mind that Memtest takes considerable time. Many people let it run over night and check it in the morning.

Question: Were your getting these errors prior to installing Service Pack 3?
