A random color appears on screen, and PC shuts down itself.

Okay so, as the title suggests, i'm having some issues with my computer. When i'm playing decent games, my PC just shuts down itself with a random color and a loud audio plays and i have to force it to shut down. It sometimes crashes, maybe after playing hours, and maybe even playing for like 15-20 minutes. I'm sure my all drivers are updated. And when it goes to a solid color, it seems like the color is based on the majority on what was on the screen before. Everything still moves, all the fans still spin, and the lights on them still glow.
My PC;
RAM: 6 GB
VIDEO CARD : Nvidia Geforce GTX 460
CPU : Intel core i7
Operating System : Windows 10 Home 64Bit

CPU and Gpu temps under load? Power supply make and model?

My first guess would be GPU instability or over heating. Both are certainly possible with a GPU as old as a 460, the thermal paste is likely dried out if it was never changed which can cause overheating. The GPU could also be degrading, if so it may no longer be totally stable at it's stock clocks and voltage, if this is the case you will either have to increase GPU core voltage or underclock the GPU to a point where it is stable.

As said by Dunlop0078 that might be the problem.

I'm not sure what model it is but i'm %100 sure it's 600W. I'll look when i get to the home.
