Something really weird
I have no idea what's wrong.
The problem is that almost all the time my games crash, just returns to windows and then windows says something about having to close the program. Also happened with firefox a few times, but games mostly.
1st I thought it would be windows, so I formatted and reinstalled windows, doesn't happen that often anymore but still happens sometimes. Also happens with all the games I have, so it's not about the game installation being corrupt.

edit: and it turnes out that those bastards at the computer shop I bought my parts from did not only send me a broken mobo, but broken ram too!
