jsc is right - your best chance is to clear the CMOS RAM. Check your mobo manual how to do that. There's a pretty good chance everything will be fine after that. Taking out the RAM (which I assume means you removed the 6GB RAM modules) won't do a thing.
Oh - and your comment about the LED RAM light still being on is a bit scary. I hope you're switching off all power before doing anything on the mobo?! Maybe I misunderstood, though.
