Query: Hub Hangs

I replaced a 3 year old cooler that was too small to use with the docking station. I liked the idea of the USB hub because I often have a wireless mouse, USB floppy, several USB hard drives, TV adapter, digital audio converter and a numeric key pad in use.The cooling fans work great and are a necessity with graphics heavy processing such as 3D games like Quake or Halo.Unfortunately, I will have to return it. When my Compaq X1000 powers on or just reboots with the cooler USB hub connected the machine hangs on BIOS initialization. I have to remove the USB connect to the cooler hub, force a power off and re-power. After Windows is up I can reconnect the hub.
