Hi, my pc recently started to crash under heavy load and wasn't crashing before. Its a fairly new computer that I've build myself (first time) so I'm a little overwhelmed.

Spec:

GTX 780 EVGA SC
GA-Z87X-UD3H
i4770k no OC
Noctua NH-U9B SE2 CPU Cooler w/Dual NF-B9 Fan
kingston hyperx beast 8gb x 2
1 SSD
1 HDD
CoolerMaster VS-Series V750S 750W Modular Power Supply 80PLUS Gold

Heres the thing, when I first build the PC I ran Furmark and it was fine. In fact it performed very well according to the stats on the website. Then I ran prime64 for CPU stress test on blend which it also did well and not crash.

But just yesterday it started crashing and restarting without BSoD. I have install WhoCrashed and did a test crash successfully but the problem I'm getting under high load I still don't get BSoD.

Now, the game I mainly play is Wildstar, I know it hasn't been optimized that well at all. It contentiously crashes my PC 3~5 minutes in when the GPU reaches about 70 degrees. And this also happens when I run FurMark now. It crashes around about 70 degrees.

I'm starting to doubt my PSU. What should I do? How do I check if its my PSU thats the problem?
I have no crash logs to show. Any help or suggestion will be greatly appreciated!

Hey thanks for the reply! But could it be faulty? I mean if it was faulty shouldn't it have crashed when I first ran FurMark and Prime95? I'm so lost and need some help.

I have no clue what to check next or even how to check next other than taking it into a shop.
