I was googled and I saw your post and because I was in the same problem I know how do you feel
the problem started when i wanted play AoE 2 it's just crashed and I got blue screen of death ,I tried everything .. nothing after that i said why not try with WOW but i got another problem it said in C++ then the problem expanded to video card Nvidia Geforce it is just crashed when i start win ,i said it is maybe just a virus I tried everything but got no sucess...
and many more
all said it is cleaned
but Finally i know what was the problem believe or not ... it was W32.parite.b that stupid worm
Virus infected almost evry .exe file on my PC..
EVen wen i tried to play any game,the blue screen flickers . And i think most of you remember the "ANNOYING BLUE SCREEN" which says please remove latest drivers or harwares u installd and some more Sh**..
I think that the reason for the blue screen was this.
W32.parite.b virus attached itself to the graphic drivers .exes (all exes and some boot sector files)That's why i was not able to play AoE 2 and wow
Finally i made it.I used Nod 32 again,it removed the virus..
