Apologize in advance. I am new to this. I have had a Gateway notebook for about two years. Hardly ever used it. It was too slow. Generally use my computer at work. Got it out and started to use it. Discovered it had only 512 ram. Best Buy installed 2 gig. Made a huge difference. Had to install over 90 updates. Took all day. Any way everything was working fine until last night when the display started to freeze. Could not do anything. Had to restart. Did it several times. I noticed that a notice saying "display driver R300 not responding" was also occuring. It said the problem was corrected but then it would do it again. Is all of this connected? I was only surfing and changing some settings, etc. What can I do to fix this?
