Said to be incompatible, the actual fault is not a true sense of incompatibility, only from the symptoms of failure and language expression on the use of the word "incompatible" is more appropriate. This failure is not uncommon, with the computer more and more time to use, monitors and mainframe components are also slowly aging, capacitance capacity in the slowly become less, resistance will have some changes, then there may be some inexplicable fault, to our maintenance bring great trouble.Here
