Hi guys I have a big problem with my UDP4 AM3 board which arrived this morning (along with a Phenom x2 550 and 4GB of DDR3)

Now I got it all setup and running fine with Windows 7 x64. I flashed the BIOS to the latest version F4G, rebooted, the system started up fine and I went into the new BIOS straight away and changed the ACC mode to hybrid. Then set all cores to -2%. Quit out of the BIOS and saved. It warned me not to turn off the power whilst it was writing to the BIOS.

As soon as I exited the BIOS, the system powered off. Now it refuses to power on and boot up!

I have tried reseating the RAM, etc, but it doesn't respond to me pushing the power button, or even if I use a screwdriver to short the power-on pins.

Have I killed it? Or am I missing something obvious?

Thanks
