    Default On board video re-enable GA-MA790GP-UD4h

    Hello and thanks in advance,

    I'll give a quick description of my problem and if you want more detail and a story of frustration please read on.

    I just put together a new system with the above board with the intent of using the on board graphics chip for a while, until I have time & money to play games again.

    I have tried setting the init display firsts as "OnChipVGA" and Internal graphics mode is set on UMA + SidePort. I have no image from my onbard gpu though. I am using my old Radeon x1650 to make changes to BIOS, removing it, then starting up.

    Any help would be much apreciated. Below is extra.

    __________________________________________________ ___________

    So when I first got the board about 2 weeks ago everything booted up fine, Vista x64 installed fine. Hooked up to my monitor via DVI-D

    Ran updates rebooted, then no display at all. Not during boot up, anything. Put in my old Radeon x1650 was able to get into the BIOS, tried choosing OnChipVGA as Init Display First and selecting DSub / DVI-D. Saved and rebooted, removed Radeon, plugged back into onboard adapter, still nothing. So I RMA'd.

    Yesterday new board arrives. This time though no image off the bat. So I throw in my card, install windows and installed the latest drives from Gigabyte's site. Pulled out my Radeon, and plugged the monitor into the mobo. Miraculously it worked...for a while.

    Same deal happened. I updated Vista, being sure not to install any drivers (as I thought that may have been the culprit last time). Reboot and nothing. Now it gets strange.

    I flashed the BIOS by removing the battery for a minute and it works, wonderful I think. Get back into windows install some software that requires a reboot. Then nothing on screen, I try flashing BIOS again, still nothing. And that is where I am at currently. I have my old GPU in now so I can see the BIOS screen and make changes.

    Maybe your onboard chip is faulty, meaning you may need to RMA it or use the older card?

    Did you uninstall the x1650 from within windows/device manger after you used it? If not, you may need to do that first as the BIOS may still think it is present if you do not. I think this may be the issue as it sounds like maybe a GFX Driver is being installed by vista if not your doing for this card. So please try going into device manger and uninstall the card from there and reboot back to vista safe mode so you know it is still ok, and so that no drivers are installed for the card. Then shut down vista, reboot to BIOS and make your changes then save/apply and exit and remove the card and see if it works then

    Here is what you should set after uninstalling the x1650, which I think you have all set correctly anyway >>>

    Internal Graphics Mode ...................UMA, SidePort, Or UMA+SidePort (Either of the three should work)

    UMA Frame Buffer Size .................... Auto

    Onboard VGA output connect ............... Auto or D-SUB/DVI-D

    Init Display First ....................... OnChipVGA (Also try PCI as this works for PCIE Card as well, so may work with onboard too?)

    On my GA-73pvms2:
    I initially had my old 6300E installed,then realised the on board graphics was probably as good.
    Entered defaults in the bios,took out the pci gx ,black screen.
    Put it back in,got into bios ok,entered defaults again,took out pci gx.
    Black screen again.
    I kept doing a full power off reboot including turning off the psu switch,I eventually got bios.(I didnt clear cmos,tho I was about to :)
    Now it works fine tho i still have to hit the Del key at just the right time ,about 2 secs into posting to enter the bios if trying adjustments.

    nb I also made sure i had just the basic items connected initially,no Lan,wired ps2 mouse and keyboard ,no external sound or usbs etc.
