My pc has started playing up...again, i attempted to turn it on today and my monitor showed no signal. i checked all the cables and still nothing. my pc does power up as the led lights turn on, i hear my hdd spin up and all my fans turn on as usual. I have tried 2 other monitors and still no luck. I have looked at some of the troubleshooter guides on this site and still had no luck so far. i have also took the graphics card out to use the built in graphics mode on my APU and used vga but still nothing
