emulatorII-list

I'm sorry for sounding noobish, but I truly am. I really need help and I'm deeply upset over my EII. I got it yesterday, it exibited some problems so after reading some forums telling me to crub all the IC contacts with alchohol I did. Now it doesn't do anything. When you turn it on, all the leds come on, the display has all black boxes in the first half of the screen and the disk drives don't do anything. Its obviously an issue with the main CPU or EPROMs I'm guessing, but what do you all think? Have I completely ruined it?!?
