I've upgraded to windows 7 on This laptop. I did a clean installed but I have the problem that almost every time I try and play a film in windows media player or windows media centre i get a blank screen. not the BSOD and the the laptop shuts down. On restart I get the message "your computer didn't shut down problerly last time etc etc"
also the same happens when i try and "rate this computer"
Any ideas why this is happening?
