The issue you're encountering could be caused by various factors, including graphics card, motherboard, power supply, or even a software conflict. It is difficult to determine the exact cause of the problem without further information and testing. Here are a few suggestions you can try:
Update your graphics card driver to the latest version. If the latest version is already installed, try rolling back to an earlier version.
Check for any BIOS updates for your motherboard and install the latest version if available.
Check if your power supply unit is providing enough power to your graphics card and motherboard. If you're using an older power supply, consider upgrading to a newer and more powerful unit.
Run a disk check and disk cleanup on your computer.
Try running the game or application in windowed mode or reducing the graphics quality settings.
If these steps do not solve the issue, you may need to have a professional diagnose and repair the issue.
