Disable Onboard Video Adapter Gateway 300S
Posted on 2006-04-09
I have a Gateway 300S and the onboard video adapter seems to have failed. I installed a PCI graphics adapter. I follwoed all standard procedures--boot to safe mode, disable AGP in Device Manager, reboot, go to BIOS and switch from AGP to PCI, reboot, install software and drivers, reboot. At this point all should be well. Not so much...
The system boots up without any trouble. When Windows XP loads all the startup programs like McAfee it appears to be perfect. Then the color goes haywire. Many times I get a very red hue that is hard on the eyes but everything is still visible. When I look in Device Manager, both graphics adapters are listed, though the onboard AGP says it is disabled.
Is there any kind of hardware jumper on the system board that will disable the onboard AGP? The only options in the BIOS is a preference being AGP or PCI, but if I uninstall the AGP adapter, it reinstalls itself on the next boot without asking. Any ideas on how to disable the AGP permanently and allow ONLY the PCI adapterto function?
