Hi!
Habe ein Problem, und zwar stürzt der PC eines Bekannten mehrmals am Tag ab egal ob man im Internet surft oder spielt. Es kommt dann ein Bluescreen mit immer anderen Fehlermeldungen unter anderem diese hier:

0X00000050
0X0000008E
0X0000001A
0X0000007E
0X0000001B
0X82C7F51E

Hiermal der HijackThis Log:

Habe G-Data und Malwarebytes durchlaufen lassen haben aber nichts gefunden!
Wisst ihr woran es liegt? Soll ich noch was posten? Gleich stürzt er bestimmt wieder ab -.-"

*push*

Heute wieder zweimal Bluescreen. Kann bitte jemand mal den Logfile anschauen ob er was findet oder ob da alles ok ist?
