I juss built a system and it has a few problems. when i turn it on the fans spin the drive lights come on (and stay on for that matter) the CPU even warms up, but i get no video i get the standard monitor test screen. System specs: Elite group ECS N2U400A mobo AMD xp 2600 Generic 128 MB RAM mitsumi 3.5" LG electronics CD-RW cant remember who makes the HDD Gainward GeForce4 FX5200
is the monitor plugged in? mine only shows a test screen if its unplugged failing that it could be any number of things, the cable to the monitor the gfx card the memory the processor(heaven forbid!!) the mobo my advice is double check absolutely everything then if it still isn't working and you have spare parts swap them in to test if there are any faulty components
if bios beeps then its something with your video...if not...well... my k6-2 system does this all the time. it doesn't like new hardware, so when I install something, I get nothing. Just wiggle your ram to make sure its properly seated. That ususally does the trick for me.
