Hi I have developed a fault with my pc today was working fine last night after a reformat. Switched it on this morning lights on, fans going etc but no signal to monitor . Tried 2 other monitors another graphics card. Unplugged and replugged everything leads memeory etc. Also no sound when pc boots. From reading some previous posts looks like it might be the motherboard it is a few years old. Is there anything else i can check beofre i go out and get another one. Cheers for any help.
