Have you seen if the issue happens in safe mode or BIOS screen? If it does not, then it could mean a driver issue. Try uninstalling the Intel® graphics driver and installing a different version.
Make sure you reset the BIOS settings to default.
If the issue appears in safe mode or in the BIOS you may have a hardware issue. Try testing the memory sticks individually
You may also want to test the processor with the Intel® Processor Diagnostic Tool.
If the issue persists there is a chance you may need to start swapping components (motherboard or processor) to determine the cause of the issue.
