A few months ago I had to rebuild my OS after a head crash and since then I'd have random BSODs typically with the error IRQL_NOT_LESS_OR_EQUAL. I analyzed the dump files and they most often stated that the BSOD was "Probably caused by: mfehidk" which is a file used by McAfee VirusScan. I sent my dumps (the files) to McAfee and they told me to remove AnyDVD. Seeing that I have used the two in conjunction for over a year, I didn't see what difference it would make. So to prove to the guy that AnyDVD has no relation, I removed it and waited for the next dump. Well, two days passed without a dump. I reinstalled AnyDVD and by the next morning, BSOD. Removed AnyDVD again and, aside from the missing AnyDVD, all was well. Reinstalled and a few hours later got a BSOD. Up until my crash, my drive had remained un-rebuilt since just after XP came out. Either something in my previous mess of files had kept this problem from happening or, one of the recent AnyDVD or McAfee updates started something. To eliminate a lot of other things, I've held off installing much else until this problem is resolved. Yes, I've checked the CPU temp and have run WinDiag and Memtest86 without any issues. OS - XP/SP2 CPU - P4/3.06Ghz RAM - 1.5Gb Anyone run into the problem? Thanks!
