Suddenly after new drivers the screen has equally spaced artifacts in shape of diamonds about 1 inch in size on desktop. Then signal will drop and monitor picks up black screen, after a few sec makes handshake. Then within a few mminutes screen and mouse will lockup a few seconds. Then full screen flashes of artifacts. Then hard freeze and can't c alt del. Have never had an issue with my 580. Guess it was more than a suggestion I was there target audience to upgrade. I wouldn't be this smart alic if it wasn't for the fact I have never ever had an issue with this card or drivers for that matter in over 2 years. Lucky for me I'm in the middle of an upgrade anyway. I have always been told not to update drivers unless having a problem but over the years nv has been so consistent I started updating day 1, guess I bare some responsibility.
