Guys, tonigh i turned on my PC and i got this message: "cannot display this video mode, change computer display to 1440x900@60HZ". I understand that its telling me to change resolution to 1440x900, but how can i do that with display turned off. I had this problem before and only thing i know is to reinstall system, but im bored of that and i just tweaked my system to run faster. It took me a week to find all that tweaks. By the way my monitor is Philips 190VW 19", maybe there something wrong with my monitor.
