I have been running WinXP and NAV2002 for a few months now without issues, but about two weeks ago I started getting BSODs, usually when using IE. I thought it was a cooling issue, so about a week ago I upped the cooling in my case but I also disabled Real Time Protection, as I know NAV can cause problems sometimes. Everything was fine, so I thought it was the cooling...until....last night I rebooted my PC (I leave it on 24/7) and within an hour got a BSOD. I noticed that because of the reboot Real Time Protection had been turned back on, so I disabled it again and things have been fine since. I have a Ghost backup from October, which I reinstated, and after NAV2002 had done it's auto update the BSODs started, which is strange since back in October when the backup was taken the PC was fine and stable, and I have changed nothing since then. Could it be that one of the auto updates for December(ish) is causing a problem with Real Time Protection?
