OK so I'm running vista ultimate and for the past 3 hours all programs stopped working except for some basic low level windows system things such as: taskmanager msconfig system restore and a few other ones. After many restarts, shutdowns, logoffs, etc. And a few windows diagnostics tools... Things slowly began to come "back to life". I have been using my laptop all day perfectly without any problems and this just happened all of the sudden. I had turned it off properly while I went out for a few hours. Turn it back on so I could logon to my favorite site *BHW* of course, and noticed the internet that when i clicked firefox it stopped working (wouldn't even open or load or show up in task manager), then i started trying other programs, ever one failed except for the above list and a few basic others. Thought maybe it was an icon issue so i went directly to the program folders and was able to navigate not launch anything inside! Virus is highly unlikely!!! If you know me you'd know why. (get's complicated nor do I want to start bragging) This has never happened though... well, not this bad. Has this happened to anyone before. Things just randomly stop working for hours and magically fix themselves after a lot of restarts, etc.(see above) Anyone know the cause? I got some lame @$$ windows forums that didn't answer the question. *If you noticed me on BHW while computer was down in that 3 hour span I was using my linux partition. Preemptive answers to questions: - Yes I'm running a legit Vista Ultimate (came w/ the laptop) - Yes I have Virus scanner(s) (very good ones not your crappy norton) - Yes I have an active firewall (very strong settings and custom config) - Yes, I am highly! Tech Savy. So no this isn't a n00b problem. - Yes I use firefox with (some might say excessive amounts) of security plugins - Yes, I actively keep my computer running smooth with programs like CCleaner and the like.
