Hi,

 

I have a Dell Inspiron 13 5378. It runs win 10 Home, and works perfectly, except - the touch screen has developed the "bubble problem"

 

This is, apparently, usually fixed by uninstalling the driver, which then forces a reinstallation upon restart and that should be that.

 

Not in my case, unfortunately. The bubbles soon reappear and render the computer totally unusable, with browser windows opening faster than I can count them, and it can take several attempts just to get into device manager to disable it again.

 

Anyone got any ideas what else might be done?

 

Thanks

You almost certainly have a digitizer that's gone wonky.  That's usually characterized by what looks like raindrops hitting the screen where "ghost touches" are occurring and, of course, driving the user insane because that going on constantly makes a touchscreen device unusable.

 

I just wrote up a set of step-by-step instructions with screen shots included on how to disable the touch screen about two weeks ago.  See:  Disabling the Touch Screen.  So, I guess, I really don't have any ideas about what else might be done other than replacing the screen (as the digitizer is typically not sold separately and they come as an assembly).

Hey, thanks for the info. That at least confirms my suspicion that it is probably a hardware problem. I've just checked, and as luck would have it, I have a few weeks left on the warranty so hopefully I'll get it fixed.
