There is no notification on phone but it still keeps charging and also there is no prompt on pc also there is nothing in the device manager
I tried different usb cables i got my usb point change on the phone i manually installed the drivers nothing wrks
Assuming you're running kitkat, try the following on the phone.


Go to settings > Storage
Click the 3-dot [or usb icon] button on the top right corner
Select Media device [MTP]
Try connecting again


PS: Have you tried connecting to another PC?
