Hopefuly you see this reply...
What size/watt power supply are you using in this computer? there is note in the installation instructions for this board about using a 2 x 12 main power connector or else the pci-e video card should have a direct connect to the power supply. Does your power supply have a 2 x 12 connector?
I can relate to the memory issue, i had to replace my system's memory because of constant blue screens, i think it was caused by the 1.65 volt memory.
