So I'm guessing I have to take another trip to the Apple Store. Here's the dealio- I have a launch 24" iMac with 2.5 gigs of ram. In March of this year I brought her in for repairs - a broken disc drive and some serious light leakage along the entire top of the screen. Cost just under $1400 to repair (GASP!!) but everything was covered by my credit card's warranty (thank goodness!). Should have just asked if I could get a new one. Anywho - they fixed her up and everything was fine. Lately, however, she has started giving me some serious problems, and I think it's got to do with the graphics card. Here's just some of the things that happen: -Frequent program crashes -Frequent system crashes/freezes -One program will crash but not the others, but everything will freze up but still keep playing (ie itunes still plays music but I can't do anything) -Lose control of my mouse -Can move my mouse but can't click on anything -Spaces/Exposes freezes and doesn't return to a single screen -Some SERIOUS graphics artifacts, such as: -Line streaks -Ghosting -Drag a window and it looks like it copie the window a hundred times, i.e. the graphics don't update the fact that I moved a window -Graphic weirdness all over the place I can't even play games at all anymore, which, along with the fact that I am getting graphic anomalies and artifacts, leads me to believe it's something to do with the graphics card. This never happened before I brought it in for that first repair though. I reinstalled Leopard 3 times. The first time I did an archive install by accident, so I redid it with a complete, fresh install. Imediately, without even installing any programs, I still was getting some graphics anomalies. So I reinstalled again and it was ok for a week or so. Now it's just gone to hell again. Ugghh. Can it be anything besides the graphics card? I have heard of some 24" iMac issues with Leopard, but I wasn't having any issues right off the bat with Leopard. And yes, I have everything up to date.
