Here's the list of parts I've got:
Tbird 1.33 (new) ; Vantec Aeroflow; aluminum shim ; AS3
Asus A7V333-X with LAN and audio (new)
Kingston 512MB PC2700 (new)
USR 56k modem
MSI GF4-MX440 (new)
Seagate Barracuda IV 60GB
Floppy
Panasonic 12X DVD
Chenming aluminum mini-tower (new)
Antec PP-352X 350W

I double and triple-checked all connections and jumpers when I put this together. When I hook the power supply cord into the power supply, the green LED "standby" light comes on the motherboard. I hit the power switch and absolutely nothing happens. It doesn't even go into post, just dead silence. I tested the power supply with an Antec power supply tester (disconnected everything else before testing) and it works fine. Any ideas as to why it won't start up would be appreciated. Thanks.

My personal mantra is to immediately clear the CMOS, reseat everything, check all physical connections, boot up first time barebones on wood table or box the mobo came in to be certain everything works before mounting in case or afterward to eliminate a short from the mix, try swapping slots with ram. Also connect the case speaker so you can hear if there are audio error codes or speakers if you have a post reporter. Post back with an update 🙂
 
I tried your suggestions. It won't come on at all. No POST, no fan movement, doesn't try to power on. I ordered another mobo (Abit KD7) and still the same. Standby LED comes on on the motherboard but nothing else. The only thing I can figure is that maybe the power switch on the case is faulty?
 
Ok, you have to eliminate some factors here. Only have the motherboard, ram, processor/heatsink, video card, and power supply. Don't have anything else hooked up (hard drive, cdrom, floppy, etc). None of the other stuff is required to post. Have the motherboard sitting on a table with the processor installed w/heatsink, memory installed, video card installed and the power supply hooked up to the motherboard.

To attempt to start the system, just use a metal flat tipped screw driver and touch the two pins that the power button normally connects to. It just takes a split second of contact and the screwdriver does not need to be held on the pins for the system to remain running, ie: touch the pins together and it should boot up. If this does not work, chances are that you could have a bad chip, ram, or motherboard. I am betting that you are shorting something out though while you had the board installed in the case because 2 dead motherboards just doesn't happen too often.

PM me if you need any more help🙂

amdskip: I tried your idea without taking the parts out of the case first. It worked. I already ordered a new case (based on my instincts) earlier this week, which will be here Friday. Nice trick. 🙂
