hi all, 
i just built a cheap pc with
amd a6-3500
 gigabyte ga-75m-ds2 
kingston valueram 4 gb 1333
 be quiet 350w psu 
when i turned it on, with dvi plugged in to the mobo, i couldn't get any video. I then put in an old gs8400, and with that connected i've been able to flash the bios and change the setting 'initial first display' to 'onboard', still doesnt work.
wondering if anybody has any ideas on how to get the onboard graphics working?
thanks
