Desperately Need Help: New GA-EP45-DS3R will not Post Consistently

Hi All,

I'm looking for some help with my new GA-EP45-DS3R motherboard. After installing it, I'm having some difficulty getting the thing to post. After hitting the power buttons, the board's lights come on, the fans spin, the disc drives and hard drives turn on, but I am receiving no video display and the board's speaker does not beep.

It will turn on inconsistently - about once every 15 attempts. During one successful start up, I was able to flash the BIOS to F10. However, after spending several hours off - I can't get it to restart reliably. I've left it running for almost 60 minutes, but still no video display.

I recently had to replace a previous motherboard that died, making the new board the only new part of this set up. Everything else has worked wonderfully and to my knowledge, continues to work well:

Case: Antec P180B
CPU: Intel Q6600 with Artic Cooling Freezer 7 Pro
Video Card: EVGA 8800 GTS, 512 MB
Sound: Creative Xtreme Gamer X-fi
Memory: (4 x 1GB) Corsair XMS 240 SDRAM, DDR2 800
Power: OCZ GameXStream 700w 12v
DVD: Lite-On 20x DVD-RW
HDD: Western Digital Caviar 750AAKS

Any suggestions?

I just called Gigabyte and they say the first post needs a CPU and 1.8V DDR2 ram if you want to reach the BIOS. Then you can change the voltage on the ram to your good memory.

I am headed to the store to test this...
