New computer build won't boot.

September 19, 2010 at 10:44:53
Specs: Windows XP

I build my 1st new computer and upon powering up the case fans and the cpu fan runs, the hard drive has power because it hums and you can feel a slight vibration, the DVD burner has power because the tray opens and closes, but the speaker gives me long continuous beeps. Also, the monitor light just flashes, meaning it is not receiving a video signal from the motherboard. According to the motherboard manual (which says to use these codes as reference only) long continuous beeps mean "Graphics card not seated properly". The only problem is that I'm using the onboard video and currently don't have any add-on cards installed. I re-inserted the memory chips one at a time and re-evaluated all my connections and have found nothing. BTW I have a Gigabyte GA-MA785GM-US2H paired with an AMD Athlon II X2 255 Dual Core Processor with a Zalman CNPS8000A Multi-Socket CPU Cooler and I'm running 2 sticks of PNY 1024MB Dual Channel PC6400 DDR2 800MHz Memory. My hard-drive and DVD burner are both SATA. Also, being the weekend I can't get any technical support from Gigabyte until Monday, so I was hoping to get a little info (if not solve my problem) before Monday. Any suggestions?

I looked over your link, do you think I should disassemble and follow that protocol? There seems to be power to all the components, just no video signal (as per the beep code).

You should strip it down and follow the procedure. It will be the only way to narrow it down.

I have my machine apart now (had a couple of laptops to work on first), power to the board is OK, case fans run, but when I apply the 12v power to the CPU I get the long continuous beeps. I used my PSU tester and it reads OK. My manual tells me that I only need the 4-pin for a dual-core processor, and the 8-pin for the quad or 6-core, but I tried both 4 and 8 with the same result. Gigabyte is still pondering the problem, I guess!
I thought with experts like y'all you may solve it before the "experts" do!
thanks again for your help!!!
