ASUS K8V-Deluxe sk939 NO VIDEO on first ever boot!

[ejr]

Although I have never been able to get a video signal to the monitor to even Overclock it!

System:
AMD 64 socket 939 Winchester 3000+
ASUS K8V-Deluxe (K8T800 Pro chipset)
(1) 512mb Corsair CMX512-3200C2 DDR400 (soon to be two 512s whenever the money tree grows a bit)
Maxtor Diamondmax 10 SATA 200GB
Ultra X-Connect 500W PSU
Chaintech 6800GT


PROBLEM:

Turned it on for the first time, no video. Tried another monitor, nothing. Tried another old AGP 4x Riva TNT2 card (nothing). Hooked monitor up to laptop VGA out and monitor works great. Realized ATX 12v (secondary) power wasn't plugged in as tight as it could be. Fixed that, still had no effect on boot. couldn't hear any POST messages so I plugged headphones in and realized it was saying SYSTEM FAILURE DUE TO CPU OVERCLOCKING!

Hmm.. impossible! Unless.. memory timings are wrong and it's automatically overclocking the CPU (due to on-CPU memory controller, right?) Well this leads me to believe I either have the wrong memory or it is not installed properly. I have tried the stick in every slot to no avail. I always see people with pairs of 512s, well, is it not okay to only run one DDR stick? Just trying to rule stuff out..

I have tried everythingg I can possibly think of...! I need some help on this one.

Is my memory correct or are the timings incorrect? I am having a hard time believing that my entire mobo is bad, that just doesn't make sense considering there are so many people with this same problem. Why did I have to have this problem too.

Any suggestions?

I've never gotten a board that wouldn't post, but maybe I'm just lucky. First, check the position of the cmos jumper. Next, recheck your power switch, reset, hd led, etc leads. Finally, reseat the 20 pin atx and 4 pin 12v connectors. If all this fails, remove the board and place it on a phonebook, and try just the video card, cpu/heatsink, and one stick of memory.

It POSTs obviously Since it says System failure due to CPU overclocking. I have removed the CMOS battery, reset the RCT (or whatever) jumper and it is *supposed* to return to normal default values to avoid the overclocking, but it doesn't! Same error over and over.


Tomorrow, I will reseat the 20 and 4-pin connectors. I hate dealing with the 20-pin wire, the one that was supplied in my Ultra X-Connect PSU is not exactly a limber piece of wire. It's STIFF and I am scared the thing is going to snap my PCB just by moving it around!


I have tried booting with nothing ( " NO CPU INSTALLED" error..) Add CPU and get no POST (not even a thing about there being no memory!)
If I install my only stick of memory, it jumps right to the overclocked CPU. ah heck.

Please help if possible? I know there are answers out there, so "bump".

don't suppose you have a cpu to try out in the system, or try that cpu in another system

Unfortunately, no, I am the only one I know with a 939.

I am going to test some other memory modules immediately after this post.

Yeah. This is pretty ridiculous!

I just tried two 256MB PC2100 DDR CL 2.5 sticks in DIMM 1 and 3 and it has video! Comes to "no bios" and then basically it is an empty BIOS.


Hmmm. So nobody ever told me I needed TWO sticks of memory to even BOOT this thing??? Why.
