I believe Intel is addressing the TDR failures with a new driver release. I'd say check Windows update later this week for a new driver and let me know if it helps.
do this. Start -> run -> type 'dxdiag' in the run window. The on dxdiag click the display tab, that will tell you which driver windows is using. Right now the latest on Windows update is 4256
Thank you Kevin for the reply.
Driver 4256 is the driver I have.
I hope Intel fixes this very soon. My hubby thinks he's broken the PC when the screen goes black. LOL
