I just bought a new Gigabyte board and am having some issues. When I boot I get a bios checksum error intermittently. I have tried updating the bios to the latest version as well. In the bios it is not detecting 3 of my voltages including 12.5 even though it is plugged in and and required for boot. I am runnning the ram in slots 1 and 2 which is dual ram(faster). I tried going to 1 and 3 slots which is single config and then my game crashed when i tried to play it. I switched back to slots 1 and 2 and the game worked but still get the intermittent checksum error. My com ports have said "failed to start" ever since i bought it. They are enabled and i checked for conflicts and upgraded chipset drivers. Its a brand new board and 550 watt ANTEC ps. Could bad ram be causing all this?
