If you don’t update the graphics with the latest version, your applications or games may not run efficiently. Also, additionally, you may experience a blue screen error! So in this segment, you will discover how to update any driver and graphics card on Windows 10 effortlessly.
Presently there are three different ways of doing this (Mentioned Two):
- Windows Update.
- Downloading the drivers yourself.
1) Alright, Now let us begin via Windows Update:
1st, You need to click on the “Start” button and next type the word ‘device manager’ in the search box. Next, you have to select ‘Device Manager’ from the search results.
2nd, Once you open the device manager, you need to find where it says ‘Display adapters.’ double-click on it. A dialogue box will open. now you should notice the name of your graphics card.

Presently you should see two choices:

- You can browse your computer for driver software.
I will select the first option. Presently Windows will search and download graphics card drivers for your PC if it discovers them and Most probably it will fix the Vac Was Unable to verify Your Game Session alert issue.
Currently, if it couldn’t find anything, you may see this message, where it shows you, “The best drivers for your device are already installed.”
However, in some cases that is not the case. The most recent version of drivers is available on the web. But it’s only that there are a few issues, and Windows couldn’t find them.
The following method is auto-detect. It bodes well! Why not let the manufacturing company that makes your graphics card verify whether you have the most recent version of the drivers or not? Also, joyfully the significant manufacturers do this very well.
I have included some official links to these checking graphics card tools. These scanning tools will examine your System and afterward download the most recent version of the drivers for you.
Update Graphics Card via Geforce experience
Another option is going to GeForce experience. if you have that for your computer. if not then obviously this step doesn’t apply. but to update your game drivers, so just go to the Drivers option and you see there’s a GeForce game-ready driver. The release date is the 17th one’s available. and they update it all the time. so you always want to make sure you have the latest one.
Solution 12, Try With a New Account
Another thing I can suggest is more of a test to see possibly if something in your account is causing your game to bug. Sometimes people will have multiple steam accounts. especially because each steam account that you create is free to make.
I would go ahead and make a brand new steam account. and try booting up and playing CSGO with that account. as you guys know csgo is a free-to-play game. so you guys will have no problem creating a new steam account.
Booting up CS:GO with it. try booting up CSGO with that new steam account. and see if the alert still pops up. if it doesn’t pop up. then that means there’s a problem within your account.
Solution 13, Uninstall Steam and Reinstall
Next best thing I can suggest is to go ahead and uninstall csgo.
1st, You can do this by simply going back up to CS:GO. right-clicking on it. hovering over manage. and then clicking uninstall right here. this will completely remove CSGO from your hard drive.
2nd, Once the process is done I would go ahead and restart your computer again. and then go ahead and reinstall it. I know this has fixed people’s problems before. so hopefully by this point, your “Vac Was Unable to verify Your Game Session” problem will be solved.
Also, I can suggest that what I know has worked for people too is completely uninstalling CSGO and then uninstalling Steam. Now, this can be a bit annoying of a process. and it can take some time but uninstall both programs. Restart your computer. and then go back online, reinstall steam and then once Steam is installed, reinstall CSGO.
Solution 14, GO Offline and Back to Online
