Welcome to bleepingcomputer!
What is the make and model of your computer, or if it's a custom built, what is the model of the motherboard? Also, what operating system are you using?
How many, and what kind of external devices are you using? I have a usb powered game controller that uses so much power from one usb port, that it will affect the performance of my other usb devices.
Try this: Turn off your computer normally. Unplug all usb and external devices except mouse and keyboard. Turn your computer back on. I then want you to plug in one of those external devices, but try one that you think doesn't use a lot of power.
If you're still having problems: If you're running Vista, go to the start menu, and in the search box type "device manager".
Under XP, or older version of windows, go to start, control panel, system, hardware tab, click device manager
In device manager, do you see anything with a yellow question mark, covered with a yellow exclamation point?
After you get back to us with this info, we can help you more!
