-Has been happening for months now with many attempts to pinpoint cause. Have come to the conclusion that it is Firefox but don't understand why. -When using Firefox, my entire PC, not just Firefox, will freeze. Sometimes it happens within the first 5min of using Firefox, other times it could happen an hour into a session. A hard restart is the only way to get back to my desktop as I have waited an hour before after a freeze and nothing happens. Mouse pointer won't move, nothing. -Initially thought it was a hardware issue or an anti-virus issue. -Reinstalled windows on three different hard drives that all pass the disk check. Still happens -Installed windows 8 to see if that would fix the problem. Nope, does the same thing on Windows 8. -Ran Memtest 86+ for 14 hours one night to see if it was my memory. Nope, zero memory errors found -To be sure I even tried only using one stick of ram in my PC at a time to see if any of the sticks were bad. Nope, it froze with every stick -Tried changing my anti-virus. It froze with every single one, AVG Free, Avast Free, Microsoft Security Essentials. -I figured out that my PC only freezes when I am browsing the web in firefox. If I use chrome or Internet explorer, it doesn't happen. These total PC freezes only happen when I am using firefox. -My only add on/plug in that I am using is Adblock plus besides the default ones that come with Firefox. -My firefox is up to date, I have reset it and reinstalled it [while only adding Ad Block +] and this still does not fix the problem -In the windows event log the only thing that happens every time my PC freezes is the Error "Session "Microsoft Security Client OOBE" stopped due to the following error: 0xC000000D", why this would only affect Firefox, I don't know. -I would like to figure out the cause of this because I would really like to use Firefox again.
