Computer upgrade 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.
OS: Windows XP

You should get one beep from the BIOS. If you replaced the motherboard,
did you properly ground it and not actually short out the powersupply
instead. You may want to start over and review in detail the assembly
instructions.

Make sure you have the power connector for the CPU plugged in (plug 2 on
page 1-7) (You can guess how I know that one!). Unplug anything you don't
need right now- internal and external DVD/CD drive, floppy, zip drive, etc.
Re-seat your RAM to make sure they're snapped in all the way. Unplug any
other extraneous peripherals like USB dives, printers, etc.
Make sure none of the mounting posts under the MB are touching somewhere
they shouldn't. All the standoffs should be under a hole for a mounting
screw to go through. Double-check all connections to make sure none are
reversed.

Did you check the BIOS to verify that
the onboard video is enabled?

 

[JS]

Bad choice of words, obviously you can't
check the BIOS with no video, my mistake.

Do you have a spare video card to try?

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.
