I just finished upgrading my computer. When I tried to boot up all I got was a nonstop beep. I have tried reseating all of the POWER connecters and cables. I have reseated the video card, the cpu, and both sticks of ram. Thinking that I might have a power supply problem I BOUGHT a new power supply did not help.
Motherboard Asus P5N32-E
Ram CORSAIR PC-6400 2GB
MSI GTS8800 340MB
Intel DUO Core 2 E6600
Thermaltake Toughpower 750watt
Koolance PC2 case
Western Digital Raptor HD 37GB
Western Digital HD 200GB
Can you boot to the BIOS,or you just get beeps?I can not boot into bios. All I get is one long beep.Please explain "upgrade".
Is this a completely new computer or an existing computer with new components added.

If this is an Award BIOS I would suspect memory first.
Either incorrect, faulty, improperly populated or not seated.

Try one module at a time.

I am feeling real dumb right now. I made a real dumb mistake. I forgot to plug in the video card. After I plugged in the video card EVERYTHING is running GREAT. Thanks for the help. The GrayBear ...... LOL ....... I'm glad to hear you sorted out the issue.
