After installing clean windows 7 usb ports doesn't work
My problem began when someday i had issue in my windows which was usb was not recognized as i tried putting 3 usbs but all of them didn't work and i have 2 usb ports in my laptop which is dell xps 15z so i don't think it is a hardware issue
My problem continued and i searched and searched the internet for solutions but no one really worked so i decided to format the windows and installing new clean windows 7 one, and i did so and after installation i had too many more problems knowing that i installed all the required drivers needed for the laptop and checked them with driver genius, now any usb i plug in isn't even sensed by the lap or self installed like the usb ports have no drivers or anything.
I tried the wireless mouse which isn't sensed on another laptop and it installed and worked instantly, so where is driver software installation which should install the mouse automatic?
and what can i do to recognize the problem? and is there anything i can install or do?
Knowing that the usb ports aren't physically defect because when i plug an old usb mouse i lights up but doesn't work cause of the mouse
please please help me i don't know what to do
