    All ina hurry I answer your problem Lets us do a test over your computer please follow the instructions.

    Warning if your USB ports are short the device you might connect to the port will burn it chip and will damage also note that you may find many or more than two ports but the power circut is same, so any port will get short the entire pc hangs or go blind. this reason also end up you entire system faulty.

    Usb devices are getting power from the systems old versions usb devices required double power so you may find olden cables having two end ports such devices required more power than the normal usb supply I hope you are ready for the action

    Connect any working USB device and see any popup messsage is coming up like Unrecoginzed device or not compatiable device that means 90% hope.

    Right click my computer icon and click properties and then do to hardware -> device manager - under USB - Universal Serial Bus controllers uninstall everything and restart your PC.

    If nothing is happened while you connect the usb device change the posrt and check each port and if every port are same I am sorry your port controller is damaged and your usb ports will not work

    thanks Hothawk

Since you've done the driver thing, the only thing left is the ports themselves. USB ports can break or malfunction very easily. I'm going to say that you will need to replace the ports.

How to enable bluetooth

Your computer has to have a bluetooth radio. You can check
Control Panel > System and Security > Device Manager
Do you see a Bluetooth Radio listed?

If not, you don't have BlueTooth on your computer so you will have to add a BlueTooth device by plugging one into a USB port.

If you have a BlueTooth radio, go to Control Panel > Hardware and Sound > Device and Printers > Add a Bluetooth Device

This option is used to connect a blue tooth device (e.g. bluetooth headphons) to your laptop through your bluetooth radio.

See this Windows web page for more information.
Set up Bluetooth enabled device

I will respond to any additional questions you have.

Hide file folder WITH A password

For the most part you need 3rd party software, or a USB drive with security built in. Just remember you are at the mercy of those companies if you lose the password. Plus some software will only works locally. For instance if someone removes the drive and connects it to another computer the files are wide open.
Win 7 Ult and Ent (high end editions have Bitlocker built in.
A simple way is to create a folder within his login account docs and choose hidden as the properties. The only way to see it would be to change folder properties and make hidden files visible. This is just cloaking, because anybody with admin rights can see them.

How to install bluetooth on my pc

This depends on what kind of bluetooth you plan on using. Certain things like a Blu-Ray DVD Drive needs to be installed and hooked up internally in your PC, while something like Headphones or a Keyboard simply just needs a USB-based transmitter or a Bluetooth card that plugs into your computer.

Hope that helps,
