I have recently come across a problem where my PC will boot up fine (all lights, fans and hard drive come on) however, my monitor just displays nothing and none of my peripherals work either. Normally the keyboard will light up almost instantly and then the monitor will show up a loading ASUS screen. The PC stays on even if you leave it for a while but still, nothing happens peripheral wise. After a few attempts everything seems to come on and work. However today, nothing wanted to work and it took a very long time until I could properly get everything on. Should this be something to worry about? The PC is basically new (9 months old) - with very good specs.
