COMPUTER RESTARTS WHILE 10 mins of running a game. :(

[abdurrahman1996]

Hello. I just got a new PC. Whenever I try to run an old or any game, the system makes a noise( black screen of death, I think) and it reboots.
PC specs:
Intel i5 3450@ 3.1ghz
8GB ram
Psu: 450v
GPU: Asus Nvidia gt 630 2GB DDR 3
HDD: 500 GB
I used this card on my old pc it ran fine. Once I upgraded my pc and updated my Nvidia driver it's crashing like this. Please help me. I'm really stressed and irritated. :| :/
