How can I temporarily disable igfxext.exe

[Sompost]

A few days ago, my laptop (Dell Inspiron 5767) became sluggish and unresponsive, CPU is constantly at or above 65%, cooling fan blasting at full power, etc. etc.

It appears that the system attempts to start repeatedly and incessantly the process igfxext.exe which dies after a few moments. There are always at least 10 instances running. For instance, if I do a taskkill, I get the following:

C:\WINDOWS\system32>taskkill /f /im igfxext.exe
SUCCESS: The process "igfxext.exe" with PID 5512 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 18340 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 1768 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 8440 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 15440 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 3904 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 17576 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 16984 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 13076 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 18320 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 5204 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 14492 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 8464 has been terminated.
SUCCESS: The process "igfxext.exe" with PID 6752 has been terminated.

A moment later, 10 more instances are running, etc., ad infinitum.

There must be a way to stop this madness.

Thanks for any suggestions.

I just killed TrueColorALS.exe and the problem disappeared.

The miracle of software...
