Hi how are you, unfortunately I did all the steps following touch screen troubleshooting but nothing worked, by also the dead lines in my touch screen increase day by day...😭 One step I still haven't done yet is to reset my PC, but I'm having some important work with my PC noadays that will delay such step. I'll get to you when I was done. Thanks for your help and concern.
