Hi Emmanuel,

If the Intel driver stopped working the causes can be many, but this issue mostly happens for one or more of the following reasons:

• The display driver is outdated, missing, corrupted or broken.
• Your video card is very old and there isn't a fully compatible video driver for your Windows OS.
• There are too many programs running at the same time in the background, which causes conflicts.
• It takes more time than permitted for GPU to display graphics to your monitor.

You can try the below mentioned methods to fix this issue:

Method 1. Update Latest Driver for Your Graphics Hardware

Method 2. Close the Running Programs as Many as Possible

Too many programs, browser windows, email messages, or game apps open simultaneously can use up memory and cause performance issues. Close those programs and windows that you are not using.

You can also adjust visual effects for better performance.

• Click Start on your computer, and select Control Panel. 
• Type "Performance Information and Tools" in the search box and select it. 
• Select Adjust visual effects, Visual Effects, Adjust for best performance and OK.

Method 3. Make Sure Microsoft DirectX is the Latest Version
If your computer has Microsoft DirectX, make sure it's the latest version. You can refer to Microsoft official site to download and install the latest Microsoft DirectX version.

I hope this helps.

Lokesh
