A local guy I know ends up with old machines that people drop off. I went to pick up an old Compaq 486 tower and he had some iMac G5's. So I said what the hell and snagged a couple machines for a few bucks. One is an A1076 (20") and the other is an A1058 (17"). Both machines show signs of bad caps.

What I want to know is I put RAM in the 17" and it bonged but nothing showed up on the screen (dark/dead). Is that just a symptom of bad capacitors or is there something else wrong with the unit?
