7 Premium x 64 was going nicely. Yesterday it froze up. I restarted it and it as slow and down the bottom right hand corner of the screen was a message that it is not a legitimate version of windows. Which is false.
I restarted again and got a black screen with a white pointer. Nothing else would come up. Safe mode would not work. I did a restore back 2 days and eventually it came good.
What happened ? anyone see this before?
