hey guys i recently purchased this board for my new build. now whereas the whole build has a long way to go before its completed, i tried to switch this board on today just to see if it would post or not. installed the cpu (i7 940 with stock heatsink), 1 memory module in the second slot (first white) and a gpu (xfx 5450). I get one short post beep and the post code display reads FF but i get no display. could this be a gpu issue or am i missing something. Ive connected a spare xigmatek 500w psu that i had lying around. please help
