Hi I have a asrock 775twins motherboard and a xpro700 pcie gfx card. I get no signal from card, upon hitting power on, the "no signal" msg dissapears but only for a few secs, then it returns. Card is lit up , fan turning etc. how does one disable the onboard vga? maybe this stopping card being detected?? Asrock website is useless on this like the manual that came with mb. I see no MB bios setting to disable the onboard vga, so im lost here. is PCIE connected with gfx card?? i see frequency thing in bios but isnt that to do with CPU setting? any help appreciated, asrock ill never buy again.
