My computer doesn't work, no matter what. Okay, first I installed a motherboard/p4 1.4ghz/256 sdram combo. It ran fine before with the p2 motherboard setup and all, then it never worked right. Now it won't do anything. You turn it on, and it just sits there with the black screen. Everything is hooked up right as far as cables and such goes. When I installed the motherboard, I thought it was a simple plug-n-play type thing. I guess not. Do I have to configure the motherboard somehow? Or is there something I was supposed to setup? The motherboard is a biostar something or another. Any help would be appreciated!!!

what size power supply are you running? might not be enough to run you video card and motherboard/processor combo? i recommend an antec-430 you need at least a 350 watt power supply nowa days. and if thats good then id try hitting f1,f11,f12 one of those at start up and setup your cmos... might be trying to boot from the wrong source?
Does the power come on at all? If not I, check the pair of wires that comes from the power switch to the motherboard. It usually ends in a connector marked "power" that plugs into the motherboard. If it isn't plugged in or is in the wrong spot you won't get any power. If you do get power, do you get any beeps? If not, reseat the memory and expansion cards and try again. If still nothing, please post what kind of motherboard you have. I can probably pull up the manual online and see if any jumpers need set.
The motherboard has to be set for the processor you installed. There should be jumpers for the clock speed and multiplyer. If they aren't set right it won't work.
Of course, I'd start with the easy stuff. Check for power.

Most newer motherboards are plug-n-play. You don't have to set the clock speed and multiplier any more.
