Low voltage due to faulty surge protectors and the add on switch panels that set under the monitor. I have had instances of both not giving full voltage and causing no end of error boxes and blue screens. It is something to check if you seem to be having these problems with no reasonable reason. I had one outlet on a switch panel that was giving only half of the 110 volts and sure enough the tower was plugged in to it. Only takes a few minutes to check and may save a lot of problems.
