Hi, Could someone please help me and tell me if there is a way I can change settings on my PC to stop it from going to sleep,...Everytime I leave it for more than 15-20mins it goes to sleep and unlike other PC`s I have seen when you move the mouse ect it dosent come back on the only thing you can do is switch it of at the mains to get back on it. Its really cracking me up so if anyone could help that would be great!
