black screen iMac, no beeps.
Hi,
I got 2 imacs 27 inch with a problem. The imac’s are starting with a black screen and give only some fan spin. When i haven’t install the ram the imac didn’t beep.
When i unplug the graphics card and start without the ram it’s beeping.
Is it a graphics card problem or is it another part?
And when it is the graphic card is reflow enough to get him alive?
