Need some help. I have a GTX 550 Ti. Playing Crysis 2 on High and at random times the screen goes blank for a few seconds and says it has lost DVI signal then it comes back on. After several episodes the game will lock up and I have to cont-alt-del. I have the latest Nvidia drivers. Any fixes out there?

Try other drivers, newest doesn't mean best, and try using other DVI cable especially if you have some cheap cable.

Got a new cable already. Anyone else having trouble with gtx 550 ti like this?
