Its a long shot,but check that you have not placed high voltages devices like UPS,stabiliser,etc. near the monitor.Also take the monitor to your friends place and connect it to his computer and you may know of the monitor is faulty.Aslo check if the signal cable is not damaged.Last but not the least,please check you have installed correct latest drivers for your OS.
See ya later,
