  1. Meaning?
    What's the monitor? What's the GPU? and what sort of UPS or Spike Guard are you using? The fluctuation depends on what sort of things happen depending on what you are doing on the machine?
    There's too little information regarding the type of fluctuations, you really need to elaborate a little on it...
