Computer will not Post

When I turn the power on mobo makes no sound. Just 4 red LEDs are on. I try to boot with bare minimum CPU, 1 stick ram, 1 video, 1 HDD and still nothing. Please help.

Try reseating everything. Also try without the HD. Does the motherboard support beep-codes, or are the LED's there to indicate the error? Either way lookup the LED code/beep code in the manual. You may also try running it outside the case in order to eliminate grounding issues.
[edit] are the fans spinning? [/edit]

Fans are spinning. I have tried CMOS reset. Tried it without hard drive.

Here is a question - I am connecting 24 pin power to MOBO. There is another 4 pin plug (12v/Ground/12v/Ground) next to the 24 pin power - Do I need to power that as well?

Yes u do... Call DFI.. I had the same exact problem a week ago. It may be that your BIOS is corrupted. They may try to flash it.

I am not familiar with that MB, but my gut feels says yes. Read the manual. Your PSU is probably new enough that it has both power connectors.
