Strange boot followed by pixelated display, what is going on?
I bought a used iMac awhile ago and now it's starting to have problems. I tried using (AHT) but my applications and any other dvd for that matter won't boot. The startup process right now goes like:
a white screen with an apple logo sometimes
a blue screen
then a weird pixelated kaleidoscope screen
what is going on? is it the graphics card or the display or the logic board? help please!
Es esta una buena pregunta?
