Hello, I've built a pc recently and I've been playing some graphic intensive games. Lately my pc has been rebooting while playing these games and now I can't even play 5minutes straight without that happening. I've checked the temperatures and they're all fine. I also did stress tests to everything and it fails immediately in the graphics. Can anyone help me with my problem?

Here are my specs:

PCU: Intel Core I5 4460 3.2GHz (3.4GHz Turbo) 6MB BOX
RAM: Corsair Vengeance 2x4096MB (8GB) DDR3 1600Mhz CAS9 1.5V
GPU: Asus GTX760-DC2OC 2GB GDDR5 PCI-E
Motherboard: ASRock Fatal1ty B85 Killer Intel B85 SK1150
HDD: Western Digital Caviar Blue 1TB 64MB SATAIII (6GB/s) - EZEX
PSU: Nox Urano VX 750w

1) First off what is your graphics card?
2) Second did you overclock your graphics card? If it is unstable then the stress test will crash.
3) What graphics driver version are you using?

That's not what I'd call a reliable PSU brand, that's most likely the issue. Do you have another power supply to try?

Sergeant just suggested trying a different PSU. Your describing a problem that is usually associated with a faulty PSU.
You using a brand that I have never even heard of.
Try a different PSU or take it to a shop and get them to test on a different PSU if you don't have one or a friend.

Sure, I will try to borrow a PSU. Also, a friend of mine told me it might be the voltages. If so, I will have to go to the store and have my motherboard checked. Do you think it might have anything to do with it?

If your not overclocking anything voltages should be fine unless your PSU is faulty or not up to the task.
There are other things that can be faulty, parts on the mobo but that's pretty hard to diagnose remotely.
The best thing to do is try other parts and isolate the problem.
If you still have problems with a different PSU then try your GPU in a different PC and see if it has trouble. Remove and test things until you locate the issue.
 

If the voltages the PSU is giving out aren't correct you will face issues, yes.

Well, that will take time, given that I don't have any other PC's and I'll have to do it all in a friend's PC, provided that he is willing to let me test these things haha. Thank you for your suggestions and I will come back with information soon

Yep, this is the kernel-power error code.

Either your psu is marginal or your system got stuck at 100% CPU usage for an extended period and the os couldn't get control back and crashed. We have this problem at work when people use the wrong psu on their laptop docking station (not enough power) in the first case, or when, strangely enough, the system hdd is going bad.

But I don't understand, the PSU has 750W. It was supposed to be more than enough to handle all of it. I guess the difference is really in the brand. If the problem is the PSU, should I invest in a better one? Or just RMA it? If so, what PSU would you recommend?

Get Seasonic. They make quality PSU's. You can't really go wrong with them.
Antec is another well respected PSU maker.
I personally only use these 2 brands for myself and friends PC's.
Some others are fine as well but I just don't need any others to choose from.
http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html
Here is a tier list of PSU's. Try and stick to tier 1-3, 1 being best and 5 being avoid at all cost. You brand isn't even mentioned that I can see which should be warning enough. Seasonic and Antec only exist in tier 1 and 2.

My GPU requires 500 watts, from what I've seen from this page http://www.realhardtechx.com/index_archivos/Page362.htm
Would you recommend this PSU? http://www.chiptec.net/componentes-para-computadores/fontes/fontes-de-alimentacao/seasonic-m12ii-620-evo-620w-80plus-bronze-modular.html It's Seasonic, 620 watts, Bronze efficiency, tier 2

Yeah mate that PSU is a popular choice and gets good reviews.
You could perhaps pick up the 750watt variant just to give you a bit of future proofing.
For instance I believe the AMD 300 series GPU's recommend 750 watt PSU's. 750 Pretty much covers the spectrum of single GPU options.

Sure, it's not much more expensive. I'll just have to order it, because it's not available in that store

Have you tested whether it is actually the problem? You might be spending money for nothing. Like I have mentioned earlier the PSU is just a likely cause. It could be a number of other things.
Though a good PSU should be able to be carried over from PC to PC for years so it's not really a waste with that consideration.

No, I still haven't had the time, with exams coming up, etc. But since you say my PSU is a complete mess, I might aswell look into some better ones, just in case.

I didn't say that about your PSU. I said I've never heard of it which could be a bad sign. It might be fine.
I still think you should identify which component is causing the problem before jumping the gun.
Even the shittiest brands can put out a PSU that does fine. It's just a higher likely hood it will fail earlier or deliver 'dirty power' to your components.
The fact you seemingly have a no name PSU and your having trouble which is quite often associated with a faulty PSU it's just the most likely cause.
