GTX 550 ti 'Out of range'

reset the monitor through its menu; the Mhz is out of range.

Thank you for the reply, but I cannot find a reset option on my monitors menu!

RTM (read the manual)

press F8 after the post screen and select enable vga mode and change your monitor resolution, select native one.

I reset my monitor and nothing worked  
I'm assuming it was the drivers I installed, everytime I try to install new drivers on my laptop it happens aswell.
I'm resetting the computer, it's taking really long, it's been about an hour and it's on %40.
I'll try what Simu said after I reset it.

I'm thinking it might be my monitor and not the computer.
I mean, even on my laptop, if I have up to date drivers and plug the monitor in it displays the same error.

Fixed it, was my monitor.
I swapped to a new monitor and it works fine.
