Pc shuts down

[Vlad Pantis]

Hello
I built a computer a few months ago and ever since it's been having the same problem: it shuts down whenever I play a more demanding game, like The Talos Principle, Skyrim etc. The screen goes black, but the fans are still running, so I have to power it off manually. I tried changing almost every component but the motherboard, I even bought a Thermalright HR-02 cooler for the CPU because the temps were high (80 degrees celsius when stress testing). Any idea why this happens?
PC specs:
Z97X-UD3H motherboard
i7-4790K CPU
Gigabyte 650 ti windforce 2gb GPU
Sirtec element bronze 600w PSU
2x 4gb Crucial ballistix sport RAM
Intel 730 240gb ssd
Thermalright HR-02 Macho rev b cooler
Zalman Z11 Plus case
1TB sata 3 7200 rpm HDD
Graphic drivers are up to date
Bios version: F8
Philips 27'' monitor (Device manager shows Generic pnp monitor)

What version of Windows is installed. My LG 27 inch monitor shows generic too. Is this your first build? Try disabling CPU throttling in the bios. Are you over-clocking?

 

[Vlad Pantis]

It's a Windows 7 ultimate SP 1. Yes, this is my first build and no, I am not overclocking, even though the CPU was overclocked by default (I don't know why) and I had to change the frequency to 4000

 

[Tmagic650]

Yes, the K on the end of the CPU number means that the CPU is unlocked and it is able to be over-clocked. Did you look at the bios settings?

If it's failing and underclocked, why push it harder???

I would bet it's the on-board GPU try one of the benchmark systems such as

I downloaded the demo and I uploaded an image of the results. When I started the test the graphic driver crashed and then recovered, but this is a problem I've had ever since I bought the GPU, long before buying the CPU and the motherboard. I even sent the GPU back to the provider twice, but they didn't find anything wrong with it and I even tried another GPU last week, but the screen still went black when playing games. I tried changing the BIOS settings to default, but it automatically overclocks the CPU to 4400 and I had to change it to 4000

I forgot to mention that I display driver crashes pretty often and then recovers

Bump

This is a symptom of a corrupt video driver or a faulty video card. This may be caused by a malware infection of some type too

 

[Vlad Pantis]

I there any way I can find out what it actually is? I installed the last driver released for my GPU and things got a bit better, the CPU doesn't overheat anymore, but the display driver still crashes. Everybody uses the latest drivers so could there be an issue with my windows?

Check the bios and turn off any CPU throttling, and C3 or C6 settings. Try playing the game then
