A8V Deluxe mobo power problems

[MDMowery]

Hey everyone. Great forum work you do here.

Onto my question. Recently I bought an A8V Deluxe mobo + other custom parts from newegg, they arrived, I put together the comp ect ect. After setting up my system and trying to boot, it appears that my motherboard isnt recieving the power it needs to some degree. I have several chassis fans connected to my power supply and they work full well + my hard drives and cd drives, so obviously my power supply is distributing correctly. I have the PSU - mobo power connecters correctly hooked up. The 4 pin + the 12 pin are working ship shape. Upon bootup though, my monitor displays "Check signal cable", which in my monitors case means no power to video card. In addition to there being no power to the video, there is no power to my keyboard or mouse. The keyboard is PS/2, mouse is USB. The CPU fan however runs smoothly, even though its power is taken from the mobo, and the mobo standby green light is on when the PSU is on. I've tried several things to figure out the problem, and I've determined it to be a defective motherboard, however I'm far from an expert in the field, so I would love any input you guys might have to help :/. I need my computer working soon for school/work projects and to RMA my motherboard and wait another week is killer, but I'll have to manage if thats what it comes to.
Thank you so much for your time, Let me know if you need anymore information.

Welcome to the Forums Look on top of your BIOS chip (located here) and one of the numbers on the sticker will be a four-digit number beginning with 100. This is the BIOS revision that the motherboard shipped with. What is it on yours?

Next, look on your Newegg invoice. Is your 3500+ a 90nm model or a 130nm (0.13u) model?

BIOS Revision is 1008.
As of now I cannot locate the processor model specs. My invoice doesn't clarify, and it seems newegg is currently down atm . If it currently helps I will give more specific specs on the processor.

AMD Athlon 64 3500+ @ 2.2ghz Socket 939
512MB Cache

Other then the model number I don't think any other specs are of use, but please let me know.
I will try to get back asap but I have a few christmas matters to attend to.

Merry Christmas, and thanks for the warm welcome .

I think what mechBgon is getting at it that newer bios revisions sometimes add new microcode to support newer processors. You may need a new bios for your cpu.

My apologies to mech if I'm wrong

That was my train of thought, yeah The 1008 revision supports the 90nm Winchester-core models, so that rules out that issue.

I guess you could check for the various things I listed in my no-POST brainstorm guide here (first link at the top there) just to make sure it's not something silly like the PSU being flipped to 230-volt input. Good luck!

Yea that was my first initial thoughts as well. So to make sure I disconnected all my fans and non essential power using accessories, eg chassis fans, cd drives ect ect. However, still no power to any USB ports, PS/2 ports AGP or PCI expansion slots. Only to the CPU fan, and the standby light for some reason :/ . My bios revision seems fully compatible with my processor, but as I've said before, I can't be 100% certain because my video has no power, nor any mobo based input devices.
My guess is leaning towards defective motherboard, so I may just have to RMA after the holidays.
Thanks for the help guys
