Thank you for contacting the Intel community.
Your best support will be with your Laptop manufacturer as they are more familiar with your system and how the components interact with each other.
However, you may want to try the following:
Run Windows® update and make sure the system is up to date and update your BIOS and for this you will need to contact your system manufacturer.
You can try our Intel generic driver, you can download it here:
I suggest you to uninstall the old driver first and the reinstall this generic driver manually.
Uninstalling the Intel® Graphics Driver and Intel® Display HDMI/Audio Driver
Manually Install an Intel® Graphics Driver in Windows® 10 and Windows 8*/8.1*
If the problem persist, try different VGA cable, if you have another spare VGA cable that you can try we can determine if the issue is with the cable or not. If the issue persists with different cable try different monitor if it is possible or try using another PC with this monitor. If this works, the laptop may have a physical damage in the motherboard.
I hope this can help.
