Im having a problem with the USB error bubble popping up constantly.. Sometimes i will get an hour or two without the bubble coming up.. but usually it pops up bout every 2-5 seconds.. As you could probably guess this is interferring with how my computer is operating.. It freezes up alot but it will resume after the freeze.. If i restart sometimes that will help a little by cutting down how many times the bubble comes up.. I dont have anything plugged into the USBs But i do have a modem connected by ethernet.. The error bubbles say USB device unrecognized after clicking on it it shows one unknown device.. I have tried powering down and shutting off the power strip.. And unistalling all devices and rebooting.. I havent tried updating my BIOS, repairing my OS install, or installing motherboard chip sets cause i dont have a clear idea of how to do that.. All of the USB ports dont work an the devices do work on another computer..
