This post describe how to install VGA controller when you Forcing Windows to Use the Standard VGA Mode Drivers Without Having to Use Safe Mode

Follow the step to Forcing Windows to Use the Standard VGA Mode Drivers Without Having to Use Safe Mode

1. When you install an OEM driver, the Windows installer program copies the OEM installation file (Oemsetup.inf) to the %Systemroot%\Inf folder, and then renames the Oemsetup.inf file to Oem#.inf, where # is an incremental number for each OEM driver that is installed. To identify the OEM video-specific Oem#.inf file, you can open each Oem#.inf file in Microsoft Notepad (Notepad.exe), and then compare each one with the original Oemsetup.inf file that is located on the OEM drivers media. After you find a match, move that specific Oem#.inf and Oem#.pnf file to an alternate location, or rename the files to a different file extension.
2. In Device Manager, right-click your video adapter, and then click Uninstall to remove the video adapter.
3. Restart your computer. After you log on, you receive a New Hardware Found dialog box with Video Controller (VGA Compatible) listed as the description and the Found New Hardware Wizard starts.
4. Click Next to start the wizard.
5. Click search for suitable driver, and then click Next.
6. Click to clear all of the search option check boxes, and then click Next.
7. Click disable the device, and then click Finish.

After you finish the preceding steps, you computer is using the Vga.sys generic video driver, and this is the same VGA driver that is used in Safe mode. Note that Video Controller (VGA Compatible) (with a yellow question mark next to it) is displayed under the Other Devices branch in Device Manager.

If the computer becomes stable or shuts down normally while you are using the Microsoft Standard VGA driver, you may need to contact the OEM driver vendor to report the problems you encountered when you used the OEM driver. You may also need to obtain and install a newer driver (if one is available) that resolves these problems.

To use the OEM drivers again, copy or move the Oem#.inf and Oem#.pnf files back into the %Systemroot%\Inf folder, use Device Manager to uninstall the VGA video adapter, and then restart the computer. Windows Plug and Play should locate the OEM video adapter and reinstall the OEM drivers automatically without requiring any user input.

Nice, practical approach from — forcing Windows to use the built-in Standard VGA driver is a good emergency step to get a system usable long enough to troubleshoot the real problem. The Standard VGA/VgaSave driver (vga.sys) is the generic display fallback Windows uses for safe-mode/basic display. (Microsoft Q&A: Standard VGA is the safe‑mode driver). (learn.microsoft.com)

Safety first: before editing drivers or system files, make a System Restore point and a full backup/image so you can recover if anything goes wrong. If the system will respond to F8 at boot, try Last Known Good Configuration from the Advanced Boot Options before manual edits — it often restores a working driver/registry set without file surgery. (System Protection / create a restore point, Last Known Good guidance). (support.microsoft.com)

Gather facts, then act: identify the adapter’s Hardware Ids (Device Manager → Properties → Details → “Hardware Ids”) so you pick the exact vendor driver, and check the Windows device install logs (XP uses %windir%\setupapi.log; Vista+ uses %windir%\inf\setupapi.dev.log) to see install errors. On modern Windows you can list and remove OEM driver packages with PnPUtil — for example:

pnputil /enum-drivers
pnputil /delete-driver oem42.inf /uninstall /force

Use those outputs to confirm which package is problematic and to uninstall it cleanly. (Hardware IDs in Device Manager, Where setupapi logs live, PnPUtil reference). (learn.microsoft.com)

If you can’t use Safe Mode, try the Advanced Boot option “Enable VGA Mode” (boots with a basic video driver but keeps other services running) as a less intrusive alternative. Remember the Standard VGA driver is temporary (no 3D/acceleration); once stable, install the correct OEM/GPU driver from the PC or GPU vendor and consider BIOS/chipset updates or hardware testing if the new driver still fails. (Advanced Boot Options / Enable VGA Mode notes). (learn.microsoft.com)
