I've recently put togther an AMD64 3400 withan Asus A8V but can't seem to
get it to boot up. I get the fans spinning but the screen stays blank and
bios doesn't load:

System:
AMD 64 3400 939 pin on A8V
RAM 2 x 512MB PC3200 DIMM DDR
ATI Radeon 9200 w 256MB RAM
IDE drives 30GB x 3
Power Supply: Allied 300W ATX

Any ideas?

Thanks,

Have you plugged in the 2x2 ATX12V power connector ? That board
has two power connectors, just like a P4 board. The processor
runs from +12V and gets the power from the separate square
four pin connector.

You aren't serious with that one? Throw that power supply away and
get something with a decent brand name of about 400w.

In the past when I've had failure to boot problems it turned out to be the
el-cheapo power supply that I'd bought bundled with a rinky-dink case.
Nowadays I buy nothing but Antec supplies and that problem never comes up
anymore.

The lesson is that it's too expensive to buy cheap stuff. You'll end up
dissatisfied and eventually buy what you should have in the first place.

I recently made the mistake of not noticing an extra brass standoff under
the motherboard. Apparently a circuit trace was shorted to ground and
caused this same problem.

Is it not booting at all or is it just allowing you into the bios once and
then not rebooting? I had the second problem and fixed it by flashing the
1009.002 bios. You can get it from
ftp.asuscom.de/pub/ASUSCOM/BIOS/Socket_939/VIA_Chipset/K8T800Pro/A8V_Deluxe/

If your CPU is a ADA3400DEP4AZ, check this article:

you won't find it. Newegg.com sells it as an OEM. I spoke with the tech
at AMD. These cpus were sold to an oem pc maker who didn't make all the
machines they had chips for, so they dumped the rest on the market.
Turns out they don't work with the A8V Deluxe. Can't really blame this
on anyone but myself. Funny thing I noticed on the newegg site lately.
The ad for this cpu says it must be purchased with a compatible MB.
Check it out!"

Hi James,

Sorry if this is a bit late for you, but it's nothing to do with your
psu.

I have a very similar setup with a $100 silent 480w supply & have
suffered the same symptoms.

The first A8V boards won't boot with dual channel RAM.

Empty the other 3 slots. Just populate "B1" (the blue slot which is
third from the CPU) and the board will go into single channel mode and
let you boot.

Once you're in, flash the m/b bios to 1.08 or later, swich off & add
the other ram & you're back cooking with dual channel...

Simple solution which is not immediately obvious.

It's a good board - the bios just needs flashing.
