usb keep restarting after plug to ac adapter

after 3 times reinstall windows and reinstall driver many times and 5 sheet of paper for logging finally i figure it out oddly: the nvidia driver cause this problem and now i don't know how to install nvidia driver properly

Have you checked your power setting in device manager. Some devices allow you to switch off the USB sockets to save power when not in use.

@ maxie, thanks for the link but i've try it and didn't give me a satisfied result still looping connection.
@ roy69, ya i've been checked that few days ago and i think i can't change the power setting even i see the tab and
it says : the hub is self-powered . and there only one "refresh" button and i can't change it.

right click on your battery icon and choose power options. Select change plan settings for the one you are on. Now choose change advanced power settings. click on the + to expand the options on USB. You will see the suspend option, change it from enabled to disabled.

i've done that before, even after bringing this laptop to service center the problem still exist somehow, and now i've some clue to what happen in this laptop few hours ago i tried disabling the Nvidia graphic card from device manager and it's work, i guess the graphic card consume a lot of power, either this is design for or i have bad IC power or anything linked to power management
