Mobo: Gigabyte GA-P35-DS3R

Hi guys, today I received a new memory kit. Corsair XMS2 DDR2 800MHz 1.8V (2x2Gb) and put them into my computer. Rather than replace my old ram, which were A-DATA vitesta extreme edition DDR2 800+ 2.0~2.1V (2x1Gb) I put the new ones into the red DDR2 slots, while the old ones stayed in the yellow.

Ever since I haven't been able to boot up the PC. I can't access BIOS either. After reading a lot of threads here today, I now realise the voltage difference could be a problem, but without access to BIOS, there's not much I can do. The monitor stays in Power Save mode the entire time.

I've tried using just the old RAM, to no avail, including one stick at a time. I also reseated the CMOS battery and have had no change.

There are no different noises from the way it would sound when I turned it on before. No beeps etc. any thoughts/ideas?


Edit: Some more info, the motherboard doesn't seem to be sending a signal to my keyboard, mouse or monitor, although my external HD lights up when I plug it into the USBs on the rear of the computer. Could the voltage issue with the RAM have blown the mobo?

The fans and disk drive all work fine.
