First of all, consider between the software, software and driver, driver and driver directly incompatible

If this is the case, uninstall the recently installed software and which, especially if your computer has two of the same type of software, such as two antivirus software.

The other thing to consider is, a system file problem, or, application and system incompatibility. If it's an incompatibility between the application and the system, then uninstalling the application will solve the problem, if it's a system file problem, then you need to reinstall the system.

The last thing to consider is hardware problems, or poor hardware contact. If it's a bad hardware contact, then dismantle the host and reinstall the memory stick and graphics card, and clean up the dust.

If none of the above works, send it directly to a service center for repair.

The solution to the problem you described is more or less the same as the one described above. In the end, all of the above methods are useless, and you can only ask a professional to repair it
