I recently had my computer worked on and just got it back. it is a HP Pavilion xt963. i have only used the computer a little bit since i got it back, but it seemed to be working fine. Then i tried to install the sims 2. it started installing and went throught the whole installation process. all was good until i tried to play the game. my computer then shut off and started restarting. it would get to the first screen that said HP and then it goes to a black screen and wont do anymore. I have tried many different things to reset the computer off the HP website. it will get to the screen where you can select safe mode or the other options, but it wont go past that. does anyone know what happened or if it was even the sims game that might have caused it? i really dont want to spend more money on fixing my computer. is there anyway i can fix it on my own?
