Hi
Last (and the first) time I came here I had questions on overclocking and made great results, so this forum was the first thing I thought off when my pc started crashing:)

So yesterday I bought WoW Legion and the same evening I experienced weird crashes. No BSOD, no weird errors. Just a screen turning grey-ish and freezing, so I was forced to hardboot. After that I received a bazillion more of those. Now I haven't had a crash since I oc'd my cpu and those crashes were, you know... considered, so I wasted hours thinking World of Warcraft broke my pc lol. I spend the whole evening changing settings, updating windows and graphic drivers, crashing, restoring windows, asking blizzard support for help, trying all these tricks and nothing worked, so I figured it could be a hardware problem.
After putting my UEFI settings to default I started testing my hardware.
I will give as much info as I can

PC Specs:
CPU: Amd pheom II 955 3.2ghz (usually oc'd on 4.0ghz)
CPU cooling: Corsair H50
GPU: Msi R7 370
Mobo: Asrock 970 pro3 R2.0
HDD: WD Blue 1TB
PSU: Corsair TX750

Findings:
-Temperatures seemed fine
Cpu 25-30 idle, 49 load
Gpu 34 idle, 72 load (usually doesn't reach 70 so was a bit suspicious here)
-CrystalDiskInfo confirmed my HDD was 'good'
-Intel Burn confirmed my CPU was stable
-Msi kombustor made my pc crash 3 times, so gpu seems to be having issues
-I didn't have time to test my ram, will do that later today after work using MemTest86.

So after these tests I concluded my gpu is faulty, but I'm not particularly a genius with pc's, so wasn't sure about this. I had no idea how to use Kombustor and I kinda just went with some random settings. I used something called 'furry' with 1920x1080 preset and no AA.

I was wondering if there are other/better ways to check if my graphics card really is the (only) problem and also how I should go from here.
Should there be a chance that the psu or mobo is the problem, then how can I find out?
I still think it's really weird this started happening right after I bought Legion, could the problem be related to that?

Also, In 3 days it's 1 year ago since I bought this card, so I'd reckon there's still a waranty on my gpu, but the retailer doesn't sell this product anymore and I couldn't find anything on the warranty time on this particular (or any) graphics card. I looked up my product order on their website and found a .pdf file considering my product which had a warranty tab, but It was blank.
any thoughts on this?

I hope anyone can help me with this,
cheers
