I did a google search and noticed many people with this same problem, but none were able to get an answer.

So I just bought a CPU set with gtx 650 TI 2gb(VideoCard), 8 gb (RAM), Intel Core I5-4670,G1(System Processor). Sniper B5(motherboard), ,800 Watts(Power Supply) from Interpace about 3 days ago and when I play graphically demanding games my computer will restart except for playing Warcraft III Frozen Throne but it restarts whenever I play Assassins creed III and IV as well as Castlevania:Lords of Shadows and Call of Duty modern Warfare II and III up to Call Of Duty Ghosts. At one time my Computer restarted with a bluescreen after I managed to play Assassins creed IV for 2 hours. My Operating system is Windows 7 Ultimate(OS), I also play teamfortress 2 and it has no problem during gameplay buts sometimes it restarts and the time interval is random usually 3-5 minutes on startup and then an hour or two of gameplay, I also tried lower all my settings especially some of the settings to none specifically antialiasing and other kinds. I really hate this unlike my Old pc that does not do that kind of stuff so I need help.
