I had recently updated the drivers to my video card. After rebooting the system a white screen with flashing grey lines comes up. There is no boot screen or anything. If I take out the card and boot it from the onboard vga port it works fine. The problem is that i would like to be able to play my games.
have you tried running sfc /scannow to see if you have any errors?
open command prompt as administrator
type sfc /scannow and press enter
theres a space between sfc and /scannow
