Logitech LCD on G15 Keyboard problems ??

I just built a Duo Core system and all of a sudden it is crashing out of Dark Age of Camelot without warning.
Two things happen:
Either it freezes completely
Or it drops the game and takes me back to Desktop.

I have seen a series of error messages;
1. Logitech LCDmon.exe needs to quit (and does)
2. IRQ Conflict ( I think I solved this one between Onboard sound card and external Sound card)
3. Bad_Pool_Header

I have not been able to get the system to boot when I place my DDR2-800 Ram 1GB x 2 Sticks into both the yellow slots or both the black slots.
I have not hooked up the front panel USB or sound outputs since I never use them.

Its got me stumped. I am thinking bad ram but it passed memory tests.

I have a DiagDX file but its very long. I can copy it in if it would help.

thanks.
