PC Rebooting randomly!

[EpicnessRo29]

Ok so I know I've made lots of threads about this and none of the solutions worked.I've decided to buy a new power supply but before that, I tried a stress test. I stressed ALL of the components in my PC and no restarts (AIDA 64 EXTREME for one hour). While I'm playing CS:GO Competitive for example, it restarts after half an hour or so... Any suggestions?

Components:

GTX 970 MSI OC (stock speeds, I haven't overclocked any of my components)

I5 4460

AsRock Pro3 Z97

SuperFlower 500W (31A on 12V Rail)

Seagate 1TB SSHD

I can post photos of stress test results and my PC components. I can't open the PSU because it has a warranty sticker over a screw. (gaaah)

*The PSU is not smelling odd and I think all the capacitors are alright*

Oh and I've played Crysis 3 and GTA V for 100+ (only 2 restarts occured I think)

it could be your psu not being able to supply enough power under load. I have the same problem with my 550w psu before, I would be playing something demanding and the pc shut itself off. Try getting another psu and testing it in the same scenarios.

I have enough money to buy an Corsair VS650 W, more than enough but there's a problem, my PC restarts while being "relaxed". I've just done an AIDA64 EXTREME test and it didn't restart for 1 hour

I have an 450W PSU and I thought I could try to use 2 PSU's to power the PC and see if it restarts

Restarts, or restart after (a few seconds) blue screen of death... If you get a blue screen of death, you should change some settings so to make sure it does not reboot after that. It will give you time to read what it said. *had a random reboot problem without load too, bad ram slot/dust, with BSOD*

Not a BSOD... It gives me Kernel 41 Error without a BSOD, it just reboots instantly

Was going to search for the answer online... Seems to be a common problem. Try g00gle first, before spamming. And you should also have listed this error message in your opening post.

Well, I googled, and there were things from "HDD shuts down after 30 mins. of idling even to the power outlet and I've solved all of those problems... I'll try to see if I can solve the problem with the answers from Microsoft
