New build is dead

[Bob]

I upgraded my computer yesterday. The green power light on my new
motherboard board comes on and the fans come on. The external power
and HDD lights come on and the lights on the external peripherals (DVD
writer, floppy, ZIP drive) flash. Then -- nothing. No video at all,
the screen just stays black, the power on the monitor button remains
yellow, and there are no beeps from the motherboard. The HDD does not
start to boot. The motherboard has on-board video, and I'm thinking
that's the problem. The CPU, the memory, and the power supply are
also new. Could any of those be a cause of no video and no beeps?

Details:
Motherboard: ASUS M4A785TD-V EVO
CPU: AMD 905e Phenom II
Memory: Crucial, two 2GB DDR3 modules.

0. Unplug all hard disks & dvd drives before further testing.
You don't need them to see the BIOS. IN fact, you should only
use only the CPU and RAM to boot your motherboard.
1. Continue with only 1 pcs of DDR3 (if the motherboard allows that)
2. Make sure that all power plugs are connected, including that
8-pin power for the on-board display!

Thanks very much for all the replies. The problem is apparently the
CPU. I put it into my other PC, which has an M4A78 PRO AM2+
motherboard. The M4A78 board should run the AM3 Phenom II
just fine, but exactly the same symptoms occurred as on my new
M4A785TD-V. Now hopefully, the M4A785TD-V didn't *cause* the
problem with the CPU ! Amazon very kindly shipped me out a
replacement CPU today.

Whoa. That's very unusual to see a dead CPU that was not killed by
something else, like a power supply failure or something. CPUs are
pretty reliable. -Dave

Thanks. I tried your suggestions 0 and 1 on your list above, and
no luck. So it would appear that the problem lies either in the
motherboard or the CPU. If the CPU were bad, could that be a
cause of no beeps from the motherboard?

Bad CPU could act like your seeing. Before considering that take the
motherboard out of the chassis and place it on a non-conductive surface and
then see how things work. Too many upgrades are shorted by an extra
standoff or a screw shorts something out with out a plastic washer under the
head.

The motherboard should beep with just the CPU only. No memory or other
cards are needed as long as the motherboard has something on it that is
supposed to beep. My last upgrade motherboard had nothing on it that could
beep, but it came with a small beeper that plugged into some pins on the
board to use for use on the power up beep or alarms.

Did he try resetting the BIOS??

Do make sure that you have the cpu 4 pin square plug fitted into the mb from
the PS.
And the PS could be the culprit as well. If you happen to have another that
could be substituted I would try it.

Indeed... never had a CPU DOA...

Yes, I was totally expecting that my test of the CPU would confirm
that the motherboard was the problem. Now I'm thinking that there's
a good possibility that the motherboard did indeed cause the CPU to
fail, so this morning I returned the motherboard also. The power
supply seems OK -- it's a new Seasonic, and all the fans run, and
the hard drives spin, but I'll be measuring all the output voltages
to
make sure.
