its possible the updates were not intended for 64 bit w7 it could be that your gpu drivers have been corrupted by the updates..
I have a Dell Studio laptop, Windows 7 64bit Professional. After installing an automatic update from Windows Update, upon reboot the screen is completely blank (actually a white color with some streaks on it). The computer boots up normally, and I can see the desktop on an external display only. So I used system restore to restore to a previous time, and when rebooting I had a picture on the screen again.
Here's the problem, after another windows update, the same thing happened, except now after rolling back the updates to a previous time, I'm still getting the blank-white screen. I've tried everything to get the screen to work again: uninstalling windows updates one by one, rebooting, system restore etc.
Any ideas what the problem could be?
