The Ati 4870 gpu in my 2008 mac pro seems to be throwing up some problems as of lately. Mainly not displaying anything at all on screen from start up. Only now and then does it get to the home screen but everything is extremely slow, unresponsive and the screen is covered in white squares. Also the card seems to get very hot when it doesn't boot correctly. Is the card basically fried?
Thanks in advance.
