http://www.avforums.com/forums/member.php?u=114247 I ask because I have got 3 games which wont work on the PC but go fine on the laptop. The games which my PC wont run are Roller Coaster Tycoon 3 , Command & Conquer: Generals and Civilization 4 which keep making my PC restart after 5 minutes but all go fine on the laptop? I have not formated windows on the PC for about 2 years now. Do you think this would stop it crashing? Also is the pc still a good system or should I upgrade this. By the way all the GTA games go fine on here like GTA VC and SA.
