Hi,
Since a month or two, Explorer.exe crashes constantly. It crashes on several occasions:
1. If I acces C:\program files (by double-clicking the folders, through the dropdown-menu everything is okay).
2. Sometimes while copying files
3. When doing absolutely nothing.
4. Just when using default programs for example Windows Live Messenger.
Next to this, my graphics-card crashes frequently, when playing games. The screen flickers, and sometimes the game will continue to run, and sometimes it will shut down. Here is the problem report from maintenance:

(I know it's in dutch, but don't know how to translate it correctly)
Tried a Virus Scan with AVG Free and Kaspersky online scanner, but nothing was found.
Since this is really annoying me, and I can't find an answer that matches my problem on the internet, I thought I could ask here. Had great help here before

Hope someone could help me?
Greetings,
Pim
