After upgrading my motherboard my machine will not POST. I get no beeps and no video signal (the monitor power indicator quickly turns from green to amber). The cooling fans run but the machine just sits there. My components are:

Athlon XP 1900+
MSI K7N2 Delta2-LSR (purchased new from ZipZoomFly 4/2006)
Seagate 120 MB Ultra ATA 100
1 stick of Crucial 512MB PC-2100
2 sticks of Micron 256MB PC-2100
Asus 9250… video card (AGP with GeForce 5200 chip)
Soundblaster Live!
Pioneer DVR-108 burner
Lite-On DVD-ROM player
Iomega Zip-250
Teac floppy drive
Enlight 300W power supply
Windows XP Home SP2


I tried the following remedies in this order without success:

Checked for grounding from misplaced stand off/base screw.

Reset the CMOS using the jumper method.
[restarted]
Replaced the CMOS battery with a known good one.
[restarted]

Verified 120V input to power supply (which is correctly set for US voltage).
Verified 12V output to yellow/black on Molex.
Verified 5V output to red/black on Molex.
Verified 3.3V output to green/black on P1 motherboard connection.

Tried a different, known good, ATX power supply.
[restarted]

Disconnected all IDE components, except for the one (known good) hard drive, which was plugged into IDE 1 and designated as master. (The cable connection was the master one as well).
[restarted]

Inserted each stick of RAM, one at a time, into DIMM 1.
[restarted after each change]

Removed IDE hard drive and installed a Seagate SATA drive (brand new and presumed good).
[restarted]


The board appears DOA. Before I request an RMA, have I eliminated all the other factors?

I would like anyone's suggestions/input on anything else I might try. I appreciate your help.
 
Just for general purposes I would try a different monitor. You boot the computer with the CPU and heatsink ONLY. If you get no beeps your MB is bad. Doesn't recognize there is no RAM in the system. HTH.

Thank you for your quick response.

I erred by not mentioning that I did change monitors early in the process of elimination. The second one also went from green to amber very quickly (so I moved on to other possibilities).

I'll have the bugler play Taps and then package the sucker up.
