No display on bootup

[Missy]

Hi all, I just assembled a new system, however running into a big
problem. There seems to be power to everything (all fans turn on, I
hear the hard drive turning on, fan on the video card is on), however
nothing is being displayed to the monitor.

I've already switched out the memory (for trouble-shooting purposes,
I'm down to one stick of RAM), put in a known-to-be-good video card
(same problem), tested the monitor on another system (the monitor
works), changed out the power supply - all with the same results. No
display at all when I turn on the system.

Doesn't seem to be the video card since there's still no display output
when I had put in another vid card.

Here's my system:

ASUS A8V Deluxe
AMD Athlon 64 3500 90ns
Radeon 9800 Pro 256
Corsair (512 x 2 DDR)
Samsung SATA HD
Ultra Power Supply 500Watts
Zalman CPU fan


Could it be the Hard drive for some reason? Could it possibly be
because the CPU is fried? I initially had an Abit AV8 motherboard
with my CPU but found out that they weren't compatible.

Another problem which is really weird is that the system won't power on
if I have the 4pin ATX 12Volt power cord plugged in. It will only turn
on with the 20 pin. Trying to figure out if this is a related problem
or if it cause the CPU to short out.

This is a really frustrating problem, and I would appreciate if anyone
has any ideas!

Be sure to put the DIMM in socket B1 -- there's a note about that on the
ASUS bulletin board. Then you should upgrade the BIOS as soon as possible.
There may also be a BIOS issue regarding the 90 nm chip -- seems to me I
recollect that there's some miimum BIOS level for those also. HTH

Missy;

Plug powered speakers into the speaker output jack. The Asus POST reporter
may be able to tell you what is going on.

Thanks for your replies guys, I got it to boot up finally. I guess it
was some sort of grounding issue with the screws on the motherboard to
case.

Now... having problems trying to get the BIOS detect my SATA HD...
