Hi guys... Just curious....wonder if i could replace Down converter, Logic Board of an old eMac GeForce2 (1st generation eMac) with the one from the boards (digital module) from the latest ATI Radeon eMac? Will it give any effect side ? Because I wanted to see how the processor works just by replacing the logic boards between another? Another problem lies on my old eMac is at certain times, the screen appear goes up and keep goes up at certain minutes...and when I leave it shut down for an hour, it appears normal,but it come back again to gos up leaving an empty black space at the bottom. Any suggestions?
