I just finished building my custom gaming pc, my connections are all right and my PCs temp is low but whenever I try to play Battlefield 1942 or Homeworld 2 it works perfectly for about a minute then either locks up, restarts my system or goes to a blue screen that occasionly has info on it that is only up for about a second so I don't have time to read it. All my drivers are up to date so what could be the problem? Any help would be greatly apriciated. Thanks. PS all my system specs are on my profile.
