USB Ports not working (not a software issue)

I have an HP Pavilion g series , Windows 7, A6 Vision AMD laptop. Randomly my usb ports stopped working all three of them. Ive narrowed it down to hardware vs software and its hardware problem. My worse fear its something fried in the mother board and I cant fix it without paying more then this laptop is worth. I've tried many things but I just ant figure it out. I looked up many threads also talking about what to do but it seems I still have a problem.

    Anything,my iphone,my mouse, my head set, laptop fan , flash drives. Nothing happens when I plug them in. Its not reading them or something
  8. I asked you before, do you have power to your USB port? If you use a laptop fan, it only use the power from the USB. That means you don't have power (+5VDC) from your USB port. Is that what happens with your laptop?

    I dont know if I have power to my usb port. How do I know if I do? I'm not very Tech savy. They worked fine one day then stopped all together I didnt do anything different.
  10. Ok, you said you have a laptop fan, is it a pad with fan you put underneath the laptop?

    Yes? I believe so it only works if its plugged in a usb port. But my usb ports dont work. I just want my usb ports to work I dont care about my fan ):
  12. I don't care either for your fan, but it gives me the information I want. What you have is, you don't have any power (+5VDC) to your USB port. What you said before, it's a hardware problem, if you have a valid warranty, use it.

    I apologize I wasnt meaning to be rude. I bought the laptop used Im not sure about a warranty and what is a 5VDC? is that something I can install myself.

    What i mean is, the motherboard do not give the power needed to use the USB port, you have the power and you have the data from the USB port. If you connect a cooling pad who just needs the power from the USB port, and the fan on the pad doesn't work, that means the USB port is not powered from the motherboard. So anything you connect to the USB port will not work. Something on the motherboard is defective, you have to go to a repair store to get your laptop repaired.
