Are there any signs of life? Fans spinning? If yes, double check to make sure the 4/8 pin CPU connector is plugged in.

Hi john2vn,

You said your motherboard tested OK, If that is the case did you try a different brand of RAM?
I have seen posts from people having trouble with certain combinations of MoBos and RAM.

I had problems with G-Skill Ripjaws 1600 MHz and a Gigabyte P55A-UD3R MoBo.
If my system was powered off for more than 8 hours or so the BIOS would not POST.

I could hear it cycling through some sort of sequence but there were no beeps or anything sane.
Bought a new power supply but no change, then after seeing posts in these forums I took computer
back to the dealer and asked them to try different RAM (CORSAIR XMS3 1600 MHz), been working
perfectly for two days now.

This may not be your problem but worth a try.

My system:
Motherboard: Gigabyte P55A-UD3R
CPU: Intel Core i7 CPU 860 @ 2.79GHz
RAM: CORSAIR XMS3 1600 MHz
Disk: 500GB Western Digital
GPU: GeForce GTS 250 1024MB
Monitor: ACI ASUS VH232H

Hello John,

Try this simple check, do what's called a "naked boot", using just your video card hooked to your monitor, and of coarse your atx, no cards, nothing else, no drives, HDD, cd's, snd cards, network, nothing, if it'll post into bios, then add on one card or any other component at a time, this will tell you what's causing your board not to go into post, is this does not work, MB is at fault.

When you say 'onboard speaker,' I trust you are referring to the motherboards speaker? You should one of these.

Yeah my PC is a new build also. The problem with the GSKILL RAM caused no post when cold booting, the
fans turned on but the screen was totally black no sound from the speaker, no mouse, and no keyboard control.
If you try junior48's idea and have no luck borrow some different brand RAM and try them.
Graphics cards can also cause post problems.
Good luck, I hope you can nail the problem and let us know if you do.
Cheers.

Are you still using the original motherboard that you were told wasn't faulty?

I'd try a PSU with more amps on the 12v rail. That PSU has 16amps on 12v1 and 18 on 12v2.
