I have an iBuyPower BB921 I bought a year ago that had no problems except for last week when it took a few tries to turn on l, but now it hasn’t turned on since! The pc turns on and the fans are spinning but the monitor, mouse, and keyboard don’t turn on! iBuyPower says it’s the video card but Geek Squad says it’s the mother board? Which one is it nothing turns on and I’ve unplugged and replaced everything and dusted everything! Maybe it’s because I need more fans in that pc I only had one in the rear!
