How do you disable the onboard graphics on an emachines C2825? I am attempting to install a Sapphire Radeon HD 4650 AGP video card, but my computer will not boot when i plug in the new video card. I have...


First of all that motherboard is too weak to fully use that video card, you could get the same framerate in games using a video card 2 generations older. 
Proper way of installing a new card:
1. uninstall the driver of the old one and reboot in BIOS - in there put all settings to auto;
2. shutdown the pc and install the new card; connect the monitor to it;
3. boot into BIOS, disable the onboard video card and reboot;
4. boot normally and install the driver.

Im trying to install agp...how do i disable the on board vga


Hi there.
Remember that if you are swapping from on-board graphics to a card you have to go into the BIOS and tell the machine that the primary graphics adapter is AGP/PCI Express.
Plug the VGA cable into the on-board graphics port, start the computer and enter the BIOS, tell the computer to use the AGP/PCI card as primary, press F10, save the changes and exit the bios.
The computer will try and restart so let it boot to post and turn it off, then put in your card and try to boot again.
Please post back if you need more help or advice.

Good luck and thanks for choosing FixYa!!

Unable to install XP sp2 on Intel D865GBF Motherboard


Maybe having trouble with a device, remove any pci or agp cards and usb devices, use built-in video until installed.

Set bios to defaults, make sure bios is latest version.

I have found this happens with a promise ultra-100tx2 and any nvidia video card.

May be a bad install cd, if you can boot it with a dos or win98 disk/CD, copy xp i386 folder to hard drive install from i386 folder on hdd by running winnt.exe

I have installed xpsp2 on about 10 d865gbf's and 2 days ago installed xp sp3 on one with no problems. may also be bad mobo.

Video card makes system unstable


Hi Wayne, it's rule of thumb to always uninstall the old software from add/remove programs before installing the newer software drivers. The reason for this uninstall is so the two programs do not over-write files with the same name.
The ASUS P4S800-MX motherboard does have an onboard graphics card, (SiS Real256E). If you added another video card into the AGP slot & did not disable the onboard graphics, than you're AGP card will not run correctly. (I'm suprised it even loaded)!
Please read page 2-19 in you're motherboard manual to help fine tune the bios when using an AGP video card. Than go to page 2-21 & than set, Primary VGA bios to; [AGP,VGA Card]. Save & exit. The PC will restart.
Press & hold the power on button on the case. This will power off the system. Unplug the power cord from the power supply. Insert you're AGP card & make sure it is fully seated. Close the case & plug in the power cord. Boot up the system. Uninstall any other software you did install for the AGP card. Retsart the PC after uninstall is complete. Install the latest software you downloaded for the AGP card. Restart after install is complete.
Lastly, run windows update service & choose ustom, not express. Check for hardware & software updates. You're system should function much better & when you check the system properties you will find you have more system memory. This is because the onboard video used you're system memory to run.

Good luck Wayne!

Mer cury PVM7 mobo wont display on monitor


So I think you are saying it did work and then stopped, right?

If that's the case then I would try booting into the BIOS setup and reseting it first. If that does not work then I would reboot into the BIOS again and see if there is something there you need to enable for the AGP port to function.

If all this fails then you most likely have a bad motherboard. It's probably not worth the money to consider having it repaired, and I doubt you'd find anyone who's even interested trying.

Good luck.

No display on monitor


no, its working as you said. try to uninstall your video if you installed to expansion slot (agp) then use the on board. that is one of the most common problems of pc specially when you're moving this from one place to another. if it boots from your onboard vga clean your uninstalled video card then reinstall to your agp. i hope that this helps you

Hp compaq dc5000 small form factor


Hi, uninstalling the onboard video will only be reinstalled by Windows next time you boot up. Disabling it in the Device Manager might and mght not do the trick if your mb is set on using the onboard. You might want to try and disable the onboard video in the CMOS/BIOS set-up. In some instances, you are asked in the BIOS what video will be used such as onboard, AGP or PCI or a selection of something like that. Also you can try and not allocating any memory to the onboard video. Hope this be of some help. Pls post again how things turn up. Good luck.
