My PC shuts down randomly when playing some games..
It shuts down, stays off for a second and then restarts.
This started a few weeks ago, PC itself is 1,5 years old and never had any issues like this!
First time it did this was while i was playing GRID 2 i believe, but mostly it does this while i play BeamNG Drive, Drive is quite heavy on the PC since it's a soft-body physics game..
And it can happen 5 minutes into the game or i can play for 30 mins and then boom, shutdown!
I know there have been posts about this same problem but I haven't found a solution yet..
I have stressed the GPU and the CPU, nothing happened during that, read on other posts that it might be the PSU, and while playing games the GPU needs more power but when i stressed it with furmark, it got up to 67 C and the fans were quite loud, while i play games, i dont think they're quite that loud so i dont think its the PSU.. Ran the windows default memory test, that didnt give any errors.. I dont think its a heat issue either because again, while i was stressing gpu it got hot but pc didnt shut down!
I checked my event logs, it seems that everytime this happens, it greats the Kernel-power Event 41.. That has to do with PC losing power all of a sudden.. So it might be my PSU?
Is it normal for a PSU to fail after 1,5 years, this was prebuilt PC so i dont know if all the components are the best of quality..
I apologize if this doesnt make any sense at all, im not that good in IT!
Here are my specs:
Motherboard: Intel DH67BL
Processor: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
GPU: Gigabyte GTX 570
OS: Microsoft Windows 8 Pro
PSU: Chieftec APS-750C 750W
RAM: 3x Kingston HyperX 2gb, 6gb all together
It might not seem like much but it was a very expensive machine for me and i get worried whenever something goes wrong.. Am i going to have to switch out a part or something?

Thanks alot if you bother to answer and help!!

It could be your PSU. Even the best PSU around can break sometime, I had a Silverstone once and it broke just under 2 years. My Gigabyte 450W is still running up to now after I bought it 4 1/2 years ago. Try Corsair or Seasonic those are great PSU.
 
Try running the CPU & GPU stress tests together if its the PSU that should make it reboot. Also its not likely the problem but your RAM should run in dual channel which needs memory installed in pairs which it can't be with 3 sticks. Its worth running Memtest to check the memory is stable too.

Ran Prime95 and Furmark together, After a minute, shutdown!
Will try to do a memtest too in the near future.
