I have an ABIT SG-80 Motherboard and am currently using a Celron D CPU. Bought it as a bundle from Tiger. Recently purchased a Duel Core Pentium LGA755 E2200 (2.2 GHz), 800 MHz FSB. I get no video & no beeping when the E2200 is installed. Tried resetting the CMOS, unhooked everything except the display & conducted a bench test. No luck. Had to put the Celron back in. Any ideas?
