Earlier this evening the screen on my iMac started flickering. Then it went all to gray. I restarted it and it was fine for a few minutes then it went all gray again. I reset the PRAM and restarted it. It worked fine for about an hour and a half. Then it went black. I restarted it and it worked for just a few minutes when this happened. It’s like my screen is split in two and moved around. I can move the mouse around but it doesn’t look like a mouse. It looks like a dotted line. I can’t do anything though. I can click the mouse but nothing happens on the screen. I think I have a screen issue! I cant NOT afford to get a new computer right now. Ugh!! Time for some research on the MacBook Air. Glad I have something to do some research to find out what this is.
