My computer monitor cuts off and on constantly. Its says there is No Signal for DVI. And then it says check video cable connection. I have done that and switched the cords and everything. Does this mean my graphic card is going out??? Please Help!! I just bought this computer a couple months ago and my 30 day warrenty is up. Do I need a new graphic card??
i would put the monitor on another pc. if you have a laptop put the monitor on it and see if it acts up. the error sound like your monitor or power supply is cutting out. monitors do have a power board and if they start going bad they can act like your telling about.
