My new monitor that I just got 4 months ago had started to blink (screen blacks out for a second like a flash) when I start up the game and during game play. At times, it would blink every 5 seconds during game play. Most recently, the game had been blinking constantly, almost blacking out the whole time while the game is still running. My graphics card is also new, GeForce 9500 GT. Also, the game does the same thing when I play MLB 2k10, so I don't think it only happens with NBA 2k10. Any help would be appreciated.
Edit: Whenever I try to reboot, my screen would say no signal and I would have to turn off the computer and wait 5+ minutes before it works again. I've never had this problem for the past 3 months.
