I just finished upgrading my computer. When i hooked it up in one room it worked excellent then i moved it to where it is going to stay and hooked everything up and it decided to give me a blue screen while starting WindosXP Professional. So i figured i would try to run only the keyboard and mouse but it still gave me the same message. So I hooked it back up in the other room and it works. The only difference between the two is keyboard, mouse, and monitor. I have no idea what is going wrong. I upped the voltage to the memory and nothing happened. Any help would be greatly appreciated.
