Help! ASUS A7V won't post!

Assembled it today, all the settings default. Jumper free and all. I plug it in and hit the power. Fans are working fine, getting power, but nothing is happening on the screen. No POST, nothing. Seems like this happens to a lot of ABIT users, but does anyone else with a A7V have this problem? Is there something I am missing?

TB 1.1
Crucial 256mb
3DCOOL case (300W)
Pioneer 16X DVD/Plextor RW
IBM 45g ata100 7200rpm
ATI All In One Wonder 32mb Radeon
 
Happens when u first set up the A7V. Hit the reset a few times. Or power off at the ATX PS and try again. WIll eventually resolve itself - can't remember how mine got fixed.
 
I'm afraid I have more questions than answers...
My 4 day old A7V133 has done the same thing. I have tried everything I can think of -- clearing the CMOS, a new battery, different video card, etc. Even a different power switch, as well as switching the power on and off a bunch of times. It ran flawlessly for 36 hours, then died. The power light on the board is on, but no post. The processor is not visibly damaged from the heat sink.
You might try all these things, most of which I learned by reading posts here. It seems to help some people get up and running, but not others. I have noticed several posts with similar problems, it makes me wonder if there might be a bad batch.
I did notice one interesting post on the ASUS forums. A system builder claimed that the jumperfree bios had increased the voltage and fried the processors on two A7V boards that he had used. I have not heard of this anywhere else -- has anybody else heard of this?
 
I've suffered through this problem with *two* a7v boards, and finally think that I've found the problem. The A7V just really sucks. Here are great things to try if you haven't yet...

1. Make sure you aren't shorting out your motherboard through its connection to your case.

2. Make sure your PS has enough juice to power your setup.

3. Try changing your memory configuration, sometimes this works on one of my boxes that suffers from this problem.

4. And this is the most effective...simply turn your computer on and off about 50 times. It seems to be a kind of a crap-shoot, and although I'm sure that this is a technical issue with a real solution, I've not be able to find it as of yet. Usually within about 50~75 resets I get my flaky system to boot, and from there it's smooth sailing. I've never had a single problem once I get it to start up...but the next time I reboot, it's back to the reset switch.

If anyone gets this figured out, I'll owe ya one...
 
There is a simple way to reset to defaults in the BIOS... turn on the PC for about 5 seconds. Turn it off with the PSU switch, not the case switch. Turn back on 5 seconds later and it should reset your FSB etc..
