Hello Jenkah,

Welcome to Microsoft Community Forum.

As per the problem description, I understand that you get

“EXT_Framebuffer_object extension was not found” error message and Internet connection error code 0x80070422.

I would appreciate if you can provide us the following information to help us understand the issue better.

  1. When exactly do you get “EXT_framebuffer_object extension was not found” error message? Does this message appear at Windows startup or while working on any particular application?
  2. When do you get error code “0x80070422”? Are you trying to turn on firewall?
  3. Have you installed any new software or codec pack recently?

“EXT_Framebuffer_object extension was not found” error message seems to indicate it is looking for an extension and can’t find it.  If you have installed any codec pack recently check uninstalling and reinstalling the codec pack and see if the message disappears.

Error code 0x80070422 is generally displayed when windows fails to turn on Windows firewall or Volume shadow copy service disabled.

Let’s try these methods below and check if that solves the problem.

Method 1: Let’s start the computer in safe mode and check if the issue persists there as well, if not, perform clean boot.

Step 1: Check if issue persists in safe mode with networking

Follow the steps in the link below to start the computer in safe mode.


Step 2: If issue does not appear in safe mode, there could be possibility of some background programs conflicting with the smooth running of the computer. To help troubleshoot error messages and other issues, you can start computer by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts.

How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7.

Note: Refer "How to reset the computer to start as usual after troubleshooting with clean boot" under more information to reset the computer to start as normal after troubleshooting.

Method 2:

Sometimes this kind of unexpected behavior shown by Windows due to some missing or corrupt important system files due to viruses and malwares removal in the past. I would suggest you to run Microsoft System file checker tool SFC /SCANNOW to scan the system integration and fix system file corruption (if any).

The sfc /scannow (System File Checker) command scans all protected system files, and replaces incorrect versions with correct Microsoft versions.

Use the System File Checker tool to troubleshoot missing or corrupted system files.

Method 3:

Virus or malware infections could also be a possible reason of this issue. Let’s scan the computer with Microsoft Safety Scanner, just to make sure that the computer is free of all infections.

Download and run Microsoft safety scanner to scan your computer for viruses


Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.
