Hello All, Just discovered this forum, its already proved quite helpful to me, but I unfortunately don't seem to have isolated my problem completely yet. Whenever I log into my cpu in normal mode, before I take any actions or access any programs, I receive a couple of McAfee Error Messages, then receive the BSOD with the following Stop message and info: PAGE_FAULT_IN_NONPAGED_AREA ***STOP: 0x00000050 (0xE2BD5000, 0x00000000, 0x804FCB3F, 0x00000001). I visited a couple of the websites suggested at the top of this topic list, and tried to implement some of the suggested troubleshooting techniques, such as removing/retesting hardware and running chkdsk (no errors found), but still receive the same BSOD shortly after any time I try to log in normally (i.e., not in Safe Mode). Even after reinsalling my Windows XP disc, very little improvement (maybe a bit more working time before the pop-ups and the BSOD). I tried contacting McAfee and having them troubleshoot, they insisted that my problem was a corrupted version of Windows (they couldn't access IE to remove or update their program). When I contacted Dell, they insisted that the problem likely lay with McAfee and that I needed to go through them to have their program removed or reinstalled. I can't uninstall McAfee myself via any normal method. I can get on IE, but can't seem to download Windows Updates any longer. So I'm left with this frustrating circular logic of not knowing where if the problem truly lies with Windows or my anti-virus program (or if this is some kind of red herring indicative of a problem elsewhere). If anyone has any ideas what I should try or where I should turn for assistance next, it would be appreciated. I am working from my work cpu now, as its hard to get much accomplished at home before my home cpu freezes. The cpu in question with the freezing issues is a Dell desktop, can try and access the minidumps and system specs later today, if that would prove helpful. Thanks for your time.
