For the past couple of weeks, I have been experienceing my display driver crashing on me whenever i'm in the middle of playing a game. I've been to the update and download driver section on dell.com but it's still crashing. Just a little while ago it when it crashed my screen dotted and my pc shut down. My driver is a Nvidia GeForce 8700M GT. I am running on windows vista and it's a 32 bit operating system on a laptop. I don't know what else to do. Please help me.
