So I recently bought a new PC, it has a Sapphire 2GB HD 6950 inside.
It was fine for like the first day of play, but after that I started to get flashing black squares in collums down the screen.
It was still playable and did not affect me. But now after awhile more squares start flashing and there are areas that I can no longer see. In SC2 I could place a building and after that I would no longer be able to see/select it. Same with a unit. Once they move from that area though i can see them again.
I thought it was because I was using a really old monitor but I switched to a newer monitor and the same problem exists
I am about to try reinstalling the graphics drivers but I would like some help as to what it could be and why it is happening.
And of course a solution.
