@sonia can you please post your Laptop exact Make and Model and Serial Number or Model number.
Since you reset your laptop it should have automatically installed the proper drivers for your IGPU (Integrated Graphics) and possibly for your GPU card if applicable.
NOTE: By reset you mean you did a manual Clean Windows Install or did your restore your Laptop to its original factory defaults like the way you first bought it?
If you did a Clean Windows Install I suggest you find out how to restore your laptop back to its original factory default state by using your Laptop's own Restore feature or Disc. If you don't know how you can probably order a Restore disc from your laptop manufacturer Support site.
Possibly by doing a Clean Windows install some critical OEM Laptop app was deleted that you needed installed to make your laptop to work correctly.
Go to Windows Device Manager under "Display" and see if there are any error there like a yellow exclamation mark or triangle or trouble code.
In fact check to see if there are any errors in Windows Device Manager. That indicates that drivers are not working correctly or are missing.
I highly advice that you first install your laptop's Support OEM AMD Drivers from your laptop's driver download page. Since your laptop's OEM AMD Driver are 100% compatible with your laptop.
If you post your Laptop's Make & Model and Serial Number I might be able to link you to your laptop's download page to download your laptop's drivers.
Run GPU-Z by TechPowerUp and post an image of it to see exactly which IGPU or GPU you have installed.
DDU is Display Driver Uninstaller (https://www.wagnardsoft.com/forums/viewtopic.php?t=3793) to eliminate all traces of your current AMD Driver from your laptop. Also before installing your OEM AMD Driver delete the following AMD Driver Installation folder at C:\AMD. You will find this folder when you click on your Windows Drive un MyPC.
