This morning my laptop wouldn't return from sleep mode, and the problem persists after shutdown and several attempts at restart.
The Startup Repair tool says: "Startup Repair has tried several times but still cannot determine the cause of the problem."
And still the starttup hangs on the black screen with the "Starting Windows" text and logo.
I tried to restore back to a Restore Point, but that tool says that no restore points have been saved,evn though I know for sure that there are saved restore points from using Revo Uninstaller.
I've also tried "Using Last Known Good Configuration" to no avail.
