Greetings all--
I risked baldness troubleshooting a similar situation when replacing a motherboard that had been 'taken out' when a video card's caps swelled and burst. I bought a replacement board, and with known good components (processor, replacement video card, RAM), had the same 'no-beep' symptoms. All power supply and case wires were properly connected, and I even tried 'known good' RAM from two other computers. I finally put the manufacturer's CD in one of my other computers to read the manual. What I found was that the particular board (an Intel DG31PR from their "Classic Series") was very finicky about RAM. It would only work with PS2-667 or PS2-800 RAM. All I had in our 3 other computers to test with was PS2-533. I'd recommend checking your manual for the board and verifying that your RAM speed is supported. Once I bought some PS2-800 RAM and installed it, the computer booted right up.
Good luck.

Subject: [PCBUILD] need help to troubleshoot a new build
Hi all,
I am trying to troubleshoot a new build. The details are:
500 watt Coolmaster PSU, Gigabyte GA-MA790GPT-UD3H motherboard,
2Gig RAM DDR3 1300 Kingston, AMD Phenom II 3x 2.8Ghz CPU, Gigabyte
HSF installed, 3 v battery good (all new components all from Newegg), there
is no beep code, nor does mb recognize mouse, keyboard, or monitor when
turned on. Mb supplies VGA. The case's power switch functions and the
Gigabyte HSF turns on. The case's speaker is attached to mb and was working
with previous mb. I believe bad RAM has a beep code. Would a bad CPU
prevent the beep codes and the BIOS from loading? Or could this be a
defective mb?
Thanks in advance for your help.
