how can i do any of this if my screen is black and my keyboard will not function?
I have an iMac A1311 21.5 inch screen. I have installed Windows 7. It worked for 5 days. Now I push power button, hear the startup chime and the screen stays black. They keyboard or mouse do not appear to be functioning, therefore I can't reset PRAM or anything else.
iMac, Windows 7
