Okay, well this weekend my computer contracted a virus (Fraud XP.Antivirus) relating to downloading a faulty copy of Avast! Antivirus. Since then I have fought the virus with Spybot S&D, AVG, and Malewarebytes. I have removed the virus and am now dealing with a more serious problem, I am getting the crash IRQL_NOT_LESS_OR_EQUAL when trying to run system intensive programs like video games. Also, my Windows Disk Check and Windows Defragmenter are not working. So far I have tried multiple anti-virus, anti-spyware, etc. I have also tried booting in safe mode, booting with all services running, and other basic diagnostics. I am running out of ideas however. I have also reseated the RAM and Video Card, cleaned out the inside of the computer, checked for overheating, and reset pagefile. I can not run memory test because when I try to boot from disk windows notifys me I can not. I am running- Dimension 8600 Pentium IV 3.4 GHZ 2 Gig RAM Radeon X1300 256Mb Integrated Soundmax Sound Phoenix ROM Bios Thanks so much for your help. Attached is the only minidump in the minidump file.
