Computer is freezing after my USB ports lose power

My computer has been freezing and i dont fully know why. When it freezes it leaves the screen how it is, no blue or black screen. It seems to happen randomly and something i notice is that my USB ports lose power and then it freezes. I'll see that my USB network adapter stops flashing and i lose connection, then my keyboard will turn off and then my mouse will stop working, then my PC will freeze. I have made sure my video card drivers are up to date, and i downloaded the USB 3.0 drivers for my motherboard and its still happening. I am on Windows 7 64-bit.

  1. Have you tried other USB 2.0 slots? KB, mouse and wifi shouldn't need or will take advantage of the 3.0 slots. Also, what mobo do you have?

    I have a gigabyte Z77x UD3H. All my USB ports are 3.0

    "Chipset:

    Up to 4 USB 3.0/2.0 ports (2 ports on the back panel, 2 ports available through the internal USB header)
    * In Windows XP, the Intel USB 3.0 ports can support up to USB 2.0 transfer speed.
    Up to 6 USB 2.0/1.1 ports (available through the internal USB headers)

    VIA VL800 chip:

    Up to 4 USB 3.0/2.0 ports on the back panel
    * Due to a Windows 7 limitation, please connect your USB device(s) to the Intel controlled USB port(s) (located below the RJ-45 LAN port) before the VIA USB 3.0 controller driver is installed."

    So you can hook up the internal headers to a backplane expansion or if you have the VIA chipset, hook up the ports under the RJ45 first like it shows above. Got this from: http://www.gigabyte.us/products/product-page.aspx?pid=4441&dl=1#sp
    Didn't know if you had Rev 1.0 or 1.1, so this is 1.1 revs info...
