I am on my new 27" iMac last night when all of a sudden the display froze and pix-elated for a second and then went black and a few seconds turned back on with an error message at the bottom right screen saying my display adapter had stopped . . . . . I was in Windows 7 64bit Professional at the time. I also noticed that Apple is wanting download a newer version of Boot Camp which I will download tonight! I went to the ATI website and found a new driver dated 4-2010 and downloaded it. All seems well but was wondering if anyone has had the same issue?
