Hi, I have been getting this error message that says: A problem has been detected and windows has been shut down to prevent damage to your computer. It then states something about MACHINE_CHECK_EXCEPTION (which I have no idea what that means) and asks me about any new hardware I might have recently installed. It also suggests rebooting in safe mode and disabling / removing any new software or hardware. I have reinstalled / changed drivers on my EVGA 8600 256 MB, AMD Athlon 64 2.4 4000+, 3com network card, and diamond sound card. My mobo is an MSI-K8N Neo4 and I have 2 GB of OCZ ddr 400. The other recent addition was a service pack 3 update for xp and after that was installed this problem occured, but not immediately. Another thing about the error message is it states that physical memory has been dumped and I am unsure of what that would mean. Any ideas would be appreciated, thanks.
