So I recently ordered a new pc from ibuypower.com (Athlon-64 2800+, Abit KV8 Pro Via-K8T800 Pro, 6800 gt 1024 MB DDR-400 PC3200) and when it I got it and hooked it up nothing happened, the screen was black and all i heard was beeping over and over again. When I called the tech support they said the ram was probably bad so they're sending new ram but I just put in a stick of ddr pc2700 ram from my other pc and Istill get the beeping. Could it be that my mobo doesnt support the ram from my other pc or is it something else wrong and does anyone have any suggestions on how I might be able to fix this?
