DDR2 Memory Problem

[DeltaPhoenix]

I've been running on 1 gb of memory (Kingston 800 mhz) for a while.
Recently i ordered another gb (same) and installed it just like the first.
But now my computer won't boot up. I tried swapping the modules, but same result.
Then i removed the old one and replaced it with the new, and then it worked. But not with both of them.

Remove your CMOS battery. Wait an hour, then reinstall your BIOS.
If that doesn't work, your board needs work.
