My screen flickers and enlarges image.
Hi everyone,
I recently bought a 2006 24” iMac running Snow Leopard 10.6.8.
I know it’s old So problems will occur.
Sometimes the screen with flicker and distorts the image. If a web window is not opened to the dispatch open say, youtube. Only that window flickers but the entire screen will do it as well.
Sometimes starts up onto blue screen with mouse icon a 1 inch squared checkered black square.
Have to press power button to restart.
Apple hardware test will not start up even with Ethernet.
I have wiped HDD, reinstallation OSX (by sharing install dvd as disc drive spots out any disc)
Checked and repaired permissions (All good) reset NVRAM and PRAM.
Is this the video card ?
Thanks.
J.
