Hi,

Install Windows Service Pack 1
http://windows.microsoft.com/en-US/w...service-pack-1
Then start with your video drivers and make sure that AVG Anti-virus is up to date.

Then if that doesn't work:
1/ Run offline Anti-virus scan http://windows.microsoft.com/en-US/w...fender-offline
2/ Run a test of your RAM. Memtest86+ Memory Testing

If you still have problems, please post the mini dumps to the forums.

Hope this helps.
