System randomly freezes, goes to black-purple-green screen with distorted sound

So I built my comp a year or so ago, and recently it started to freeze at random times, while I'm playing games, surfing, doing some work. It happens mostly when I switching tasks, from a game to my internet browser or smth like that. And I have to restart the computer to get it going again.
I can't figure the reason for this. I installed Win 7 again, formatted everything, updated my bios etc.. ):
Could it be something with the power supply? Or is the RAM simply faulty?
Any help would be appreciated!
Thanks in advance. :D
Here is my spec:
Corsair CX600W
Seagate Barracuda 1 TB HDD SATA
Solid State Drive (SSD) 2,5" SATA 6Gb/s SAMSUNG 840 Pro Series, 128 GB
DDR III Kingston 4GB 1600MHZ HyperX
Z87-K Asus Motherboard
Asus Nvidia GeForce GTX 760 DirectCU II OC 2GB GDDR5
Intel Core i5-4670K, 3600 MHz

  1. if you are using an HDMI connection [ with sound ] its almost certainly an issue with your graphics driver . Try updating to the latest version
  2. Yep, I'm using that. But I'm an avid gamer, and I can assure you that these drivers are always updated :D
  3. I have the exact same problem!
    I updated my nvidia driver and the only thing that changed was the color of the screen when it got frozen again.

    Any solution to this mindblowing issue? ): ): ):
