This could be a heat problem. Check the conditions inside the case as 
well as the case filter, if there is one on your case. If the dust is 
overly excessive, you may want to take it outside and blow it out with a 
canned air product. You should keep the fans from rotating, Q tips work 
well for this.

I hope this helps.

No power gets to the USB hub light.
