Display fuzzy, stuck at start screen
my iMac (24", 3.06GHZ early 2008, NVIDIA 8800GS) has suddenly an issue with the gpu or so, while working the display went very colourful and got stuck. After hard shut off and switching it on, the display keeps stuck at the start screen (with the Apple logo). The image looks fuzzy, here is a photo of it:
Nevertheless the iMac is booting! I can hear the login sound from skype and I can ssh into my iMac using my iPhone. The screen still displays the same start screen. With time the top of the iMac gets really hot, therefore I shut it off after making a final TimeMachine Backup.
Is this a GPU issue? I saw a replacement GPU (installed is a NVIDIA 8800GS) at ebay for 200£, or is it more likely an issue with logic board.
Esta é uma boa pergunta?
