Is your equipment grounded correctly?

In some cases, the problem can be solved by electrically grounding a 

metal component of your computer or the ground pin of your computer’s 

power cord. You should also check whether a strong magnetic field is 

being generated by a nearby device such as a television or microwave 

oven.
