Dell G3 15 3590 Touchpad problem(stopped responding)

Hi,

I have problem with my Dell G3. Yesterday my touchpad suddenly stopped working. Keys on it works but left and right key works as left key(for example I can only click on the folder but not see properties of it, past option, copy etc.).  It completely doesn't react to my touch. When I plug my USB mouse it is working, but my Touchpad still doesn't. I tried reinstall drivers from Dell site and run tests to see if my laptop will detect problem but it says it works properly. In settings my touchpad is ON and it says it will work with my usb mouse pluged in too. I tried to see if I can do test in ePSA but I don't see touchpad option here. Keyboard, usb and other devices are here but not it. Does anyone have an idea what could have happened and how to fix it?
