I'm upgrading an old P2 system. I ordered the following: Mach Speed V2DP motherboard, AMD Sempron 2400+ (1.67 GHz), 512 MB PC2700 DDR RAM. I put the thing together, as of now the processor and memory are on the motherboard, nothing else is hooked up. The monitor is hooked into the video port on the motherboard. When I start the computer, the CPU fan starts up (indicating to me that there is some power on the mobo. When I first tried it I had the hdd, CDdrive and floppy drive hooked up, and I heard the CD drive start up (there was a Win98 install disk in it that I had forgotten to take out) run a little, and shut down, so there is some activity there. My problem is that I get no video at all. Just a black screen. What is my next step? Any input would be appreciated.
