When I try to open games on my computer, visual errors prevent the nvidia gpu from working. When I open msconfig and turn off the delltechhub service, the problem is solved, but Dell applications do not work (supportassist, alienware command center and FN keys). Even though I received Dell technical support, my problem was not solved.  I've never had a problem like this before.  I was told that this problem was due to the latest updates and that I should wait for the new software update.  I can't really use my computer.  I want it to be resolved urgently.
