usb keep restarting after plug to ac adapter

[hnf a]

hi all i'm new in here and i want to ask why when i plug my ac adaptor all of usb port seems restarting, when i plug my android to usb port the phone keep reconnecting to the laptop and the hard disk make strange noise like when the laptop start, but after i unplug the ac adaptor all of the problem seems disappear, i think there is something wrong in the driver because i use win 7 in a win 8 laptop that all of the driver is only supported win 8 OS, can anyone at least give me a way to check if the driver is wrong or faulty?

When you plug the AC in, the PC gets an interrupt to which it reacts. And the noise is probably coming from your optical drive which is also on a USB port.

For how long period you have been using this Ac adapter. may be it got fried if it is under warranty period then exchange it or not then buy the new one i think their is problem with the Adapter only, check out the online stores like Amazon, Sfcable, newegg etc.. to buy a new one.....

Hi there ... Where did you Install the Chipset Driver from ? ... Going by your Specs i see you have one USB 3 port is that correct ? ...

@johnkarter87: i think there is nothing wrong with the adapter, i just bought it few days ago and i've try another os and nothing wrong when i plug my laptop to AC supply.

@maxie: i've download it from the asus official website, yes i have 1 usb3 port

@whs: i'm pretty sure the noise is coming from harddisk because when the laptop start making that noise the hdd lamp just off for few second

That is very unlikely. But you are closer to the action.

yesterday i try with featured phone and all still give me same result the phone still reconnect for several times in minute and obviously cannot transfer data or modem mode, i think the problem is in the driver but i don't know what driver should be downloaded.. is the chipset driver that i should redownload?

i am really sorry for the misinformation, it seems whs was right about the ODD i think the odd was kinda resetting once a while and ya at few days ago i played some game, when the ODD start making noise the game sound just broken or dead for half a second, and few days ago i've trying to reinstall the driver by downloading it straight from intel website for few hours i'ts works pretty well but then after few restarting the usb problem goes back again i don't know what to do.

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
