I just got a new CPU and Motherboard and after switching everything over I turned it on, and it started to boot, but it gave no RAM beep, it just turns on, but the computer does not display bios screen or anything. (a.k.a. it powers on but does not actually start to boot) It is a new board and the model number is P4M800-M7. Will I have to clear the C-MOS before it will recognize the ram? It is kingston 512mb PC3200 ram that is not duel channel. Does anyone have any ideas why this might happen? I have only used pre-tested Motherboards so I have never had to clear the C-MOS.
