Windows XP Service Pack 3 RC Under Intel Core 2 Duo 2.33Ghz 2GB of RAM 1st : Before any of this happened, i was playing a few mmos and whatnot (Not WoW). After some restart, computer suddenly just hangs and crashes upon start-up (or just loads rather slow.) I got chances and instances where i got my Process Explorer opened, saw that WinLogon.exe, svchost.exe, lsass.exe are all trying so hard to process lag the processor. for svchost.exe i noticed before this, it was starting iexplorer.exe, multiple instances of it... but i never see it on any of my active windows. Currently i'm on UBCD4Win CD (booted from it... booting unto the WinXP installed on my C:\ is rather... hard) and trying to figure what the hell is wrong. I can't enter safemode either. I experienced this before, but only with Explorer.exe / taskmgr.exe lagging each other to hell -_- (it was fixed when i killed the threads of the ones lagging, removed this RavMonE.exe whatever it was, and restarted the process) it seems it has taken over that really vital program / services :/ I might point out that, the source of this is from autorun(s) of external harddrives... 2nd : anyways, i reinstalled Windows XP Service Pack 2 from my disc... and i got this dump message about my Video Driver not loading.... as on the dump. Still and currently i cannot jump directly to my WinXP installation, still using UBCD4Win to... >_> yeah... get on the internet, minor things.... My uncle already said that they're going to reformat it... but i dislike reformats without knowing what was the problem's cause. Anyways i await any one who has experienced this.
