I put togather my new comp its a soyo dragon 2 motherboard, 1 stick of 256mb PC400, Nvidia 5700U, 480 watt PS, and a P4 3.0e. My first problem is that it would start and then restart then restart again it would only be on for like 30 sec. I put more compound on the cpu and now turns on for about 15 seconds the restarts and stays on for ever. Heres my other problem when its on I dont get an image on the monitor its just black/gray. Ive plugged the monitor into the video card and also the motherboard. All my fans are working my cd drives are working too. Im trying to start the comp on a preloaded windows hard drive so is that the problem? If not then whats wrong with it and what can I do. I also get no beebs or anything. I've cleared the jumpers and everything still no image. Help me please.
