I have a strange problem with my new build. I've searched around, but don't really know what search terms to use. Here are the parts:
CPU: AMD64 3400+
Motherboard: ASRock K8NF6G-VSTA 754
Video card: EVGA 320-P2-N815-AR GeForce 8800GTS 320MB
500W power supply
2 IDE drives
1 SATA drive
The processor and drives were actually from an old build. I can be more specific about the drives/PSU if requested.
Originally, I tried using an old 400W power supply, but couldn't get it to boot. It powered on for a couple seconds, then turned off again. I did some digging and decided that I probably didn't have enough power, so I ordered a new 500W power supply. (The video card says it requires a 450W one, so I decided to go a little higher to be safe.) So I got my new PSU, installed it, and tried turning it on (no monitor, mouse, or keyboard hooked up). Everything seemed fine. It turned on and stayed on. So then I hooked up the monitor and everything was still fine. It started booting correctly. Then I turned it off and hooked up the keyboard, mouse, and ethernet cable. As soon as I did that, it started doing the same old turn on/turn off routine. I unplugged the keyboard, mouse, and ethernet cable, and it continued to have problems. Now I can't get it to boot at all.
I'm not really sure what to make of this. The only thing I can think of is that the extra power required for the USB devices caused it to not have enough power, but that seems kind of ridiculous, especially since it no longer works even without those devices. Does anyone have any ideas on what my problem might be? I really appreciate it.
