I need some help. I just purchased a bunch of parts for a new PC. Here is the bulk: Intel core 2 duo 1.8 ghz ECS motherboard w/ intel 945 chipset ATI PCI express Radeon X800 GTO 1 GB Crucial memory 350 GB Seagate HDD I put it together once, tried to boot it up, everhything spun up fine but no video signal went to my monitor. Tried two other monitors, two other video cards, pulled one stick of memory out, then swapped it with the other. Unplugged everything unecessary to get it to boot. I then exchanged the motherboard out and still I got no video. Is it a motherboard issue, a CPU issue, or a powersupply issue? I have an ANTEC 350W 24 pin power supply. I am pretty mad since everything is brand new. Thanks for any help.
