I have a gigabyte ga8 pe800 mobo and I added another gig of ram now my pc will not respond at all. I plug in the power cord, the fan spins for a few seconds then stops. nothing happens when I press the pwr button. I tested the PSU it works fine. Is there a reset on this mobo?

Check your ram configurations in the manual. Some boards have restrictions about using 3 sticks in a 4 slot board, or mixing single and double sided ram.
a goo try is pull out the BIOS battery on the motherboard.
