I got a Dimension B110 and a Dimension 4300. I'm trying to take the dimension 4300 cpu and put it in the B110. Everything i've read says i should be able to do it. It's a p4 1.6ghz., 400hz, 478pin, ect. It supports all the technical stuff i think. Whenever i plug the power cable into the back the computer boots up on its own and the screen is just black. It says it's in a power save mode. The tower is in some power save mode too i think (an orange light on the front lights up). I've updated my bios to A01 and a lot of my drivers. Anyone know what's up? Thanks. and there are no beeps when it turns on.
