PC crashing during games?

[Nemozzz]

Hi!
I have a pc which i use for playing games. However when i am playing games, the computer will crash randomly. Any ideas why?
PC specs:
CPU: intel core i5 2500 @ 3.30
RAM: 8gb DDR3
GPU: Nvidia geforce gtx 650 ti (boost) (1gb ram)
OS: Windows 7
I play games such as Tomb Raider and Assassins Creed Black Flag.
Thanks!

Also my CPU runs average 34°C and 56°C when running games.
My GPU runs average 27°C and 55°C on games!

Update your video driver. Run Windows update.
Restore your system back to a time you know it worked.
Update all of your MOB's drivers.
Make sure your PSU can handle your system.
Get a good PSU. Cheap unbranded PSUs will cause tons of problems.
I would get EVGA, Corsair, or Seasonic.
