Windows 7 64 bit: I’ve had a problem with a blank screen when the computer awakes from sleep. I’ve tried many things without success (startup program conflicts, graphic driver update, new graphic card, etc.) all to no avail. I’m about to install a clone of the hard drive that I made with Acronis about ten months ago. However, I’m concerned that the dark screen problem might be caused by one of the many Windows updates. Is this possible? I can turn off the automatic update before I reboot, but how should I then ignore all the updates that Windows suggests?
