Another option to obtain help in Windows is to use the Obtain Help app to contact Windows Support. Third-party programs are also available for debugging specific devices, such as your display. Conduct a thorough investigation and scan anything you download for malware.

Your CPU and other components may include diagnostic software. For example, the Intel Processor run Diagnostics Tool can evaluate and improve Intel CPUs. Dell computers also have a variety of diagnostic tools. Check your PC for any additional built-in diagnostic applications.
