My monitor starting blinking off a week ago saying no input. I would restart the computer and it would work. It started doing it more frequently and then last night, it did the same thing but now when I restart the computer, the blue light showing the computer is on lights up but nothing works at all. I use my computer to charge my MP3 player and it wont even do that. This sounds like a possible problem with the power supply. The computer is 3 years old and just looking for some imput as to if you agree on this or if there is anything else I can do before I replace the power supply.
