I upgraded my old system to the following components- P4 3.0 with the Asus P4C800. Everything is where it belongs but the system will not boot. There are no beeps and even worse, there is no video. It doesn't sound like anything is going on- it's not like the hard drive is being accessed to load the OS, so it seems like it's something with the power of the CPU. Any ideas what the problem might be? The power supply is a brand new True Power 430, so that really shouldn't be an issue. It seems pretty certain that it's not the video and that card has been working fine anyway....so any ideas???? Thanks very much in advance!
