First:

Use the Dell Driver Update App and update all Drivers including BIOS (UEFI), Chipset, and Video for certain and all other drivers.

After the restart that occurs, update Windows fully . Check in Optional Windows Updates and do those as well.

Second:

If you still have issues, Use the Dell Hardware Diagnostics App and test all hardware.

If there is a hardware issue, you may need to have the machine serviced.
