Hi,

I'm not really good with hardware and software but I know the basics.
Today, all of a sudden, my PC crashes to a black screen with a sound lopp when playing games, be they battlefield 4 og something less demanding like serious sam 3.
I'm not sure what's causing this, but it pretty much renders my PC unable to play games.
A week ago I updated my bios to the latest driver (it hasn't been updated since I purchased it 1½ year ago; I'm not really good with hardware). It went smooth with Asus "ez-flash" or what ever it's called. I also unparked my cpu cores. This was all done to increase performance and it did indeed increase performance, without any problems.
But when I booted up my PC this morning and started playing battlefield 4 I crashed to the black screen. And when that happens I have to do a hard reset with the button on my PC. That happened a couple of times, regardeless of which game I played.
I the tried to park my cpu cores again, but to no effect.
As far as I can tell from gpu-z my GPU is doing fine, so I'm wondering what the hell has happened. Maybe I screwed something up ?

My specs are:

Windows 7 64-bit
intel i5 3750k
Asus p8z77-v lx (the update I installed: P8Z77-V-LX-ASUS-2303)
Asus gtx 770
8gb ram

I'm really at a loss and hope that some of you can help me figuring out whats wrong !
If you need any details, just say so. I'm not really suer what to provide other that my specs.

Thanks in advance !

I have a 750w psu form Cooler master. For some reason I can't find a link to an english website. http://www.compumail.dk/vare-oversigt.php?varenummer=30766&type=hardware

Parking my cores. Well it means very little to me since I don't know a whole lot about it. But I basically just use this software (http://www.coderbag.com/Programming-C/Disable-CPU-Core-Parking-Utility) to unpark them since, for some reason, they are parked by default. It's something like the OS sets a side cores(park cores) to do tasks in the background while you play games on your unparked cores, so if you unpark all the games will have more cores avaiable. But the again, I have no clue if the problem is related to this since it worked fine for a whole week and persists after I parked them again.
Furthermore I installed a new GPU (the gtx770) a month ago. Don't know if that is cause the problems, since it has worked fine up to this day as well.
Even further more. I looked in the eventwvr, and I couldn't really find anything that stood out. There was a 41 Kernel-power but I think that's from me pressing the power button on the PC. There are two "NvStreamSvc" but I think they happened as the PC was rebooting.

Okay, I'd unload that "core parking" application from your PC. Just let Windows 7 control the allocation of CPU's.....

The new CPU presents a fairly heavy load. Cooler Master is not the best of power supply brands, but, it Should work per the specifications. Per NVidia you need 42A (amps) on a single rail for +12v (volts) and you have 60A.....

Output Current +3.3V - 25 A ¦ +5V - 25 A ¦ +12V - 60 A ¦ +5VSB - 2.5 A ¦ -12V - 0.5 A

Next thing I would check are CPU (< 80C is good) and GPU (< 85C is good) temperatures. Download "SpeedFan" or "CPU-Z" or "GPU-Z" for getting temps..... (dirt and dust will build up about fans, without regular cleaning this will greatly increase your temps. Unplug the system and Carefully clean with can of compressed air and vacuum cleaner....)

I've turned it off :)
As far as I can tell my temps are fine. The GPU never goes higher that 65-70C. I just ran Serious Sam 3 (a game) for 5-10 minutes and the my PC crashed. The last time I checked during that gameplay my CPU temp was 65 which isn't that alarming according to the temperature you mentioned.
In regards to dust the PC is faily clean. The GPU is spotless as it is completely new.

I'm assuming you removed the old video drivers and install the latest NVidia drivers from NVidia.com website?

Could try to isolate the problem by removing the GPU card & playing games off the on-board graphics (Serious Sam would likely play on low settings....)
- this would reduce load on power supply
- and remove the GPU component completely from the equation

Yes, I have all the latest drivers.
If I do as you say and it still crashes that would mean that the GPU isn't the problem right ?

For some reason I could not load any games when I took out my GPU.
How should I proceed ? Or should I just take it to the place I bought it and let them deal with it, since it's still under a warrenty ?

Makes sense and I haven't got any spare parts. But they'll surely have.
Thanks for your help man !
Have a great day
