My computer is about 18 month old and recently(about 2 months) it started restarting firstly once a day in graphics intensive games like wither 3, and now it does it strangely at every end of a game i play such as Heroes Of The Storm(doesn't matter if its 12 minutes or 24 minutes), Overwatch at the of a round but usually it is the 3rd round. This happens only at the end of the game, weird right? In Shadow warrior 2 it restarts aster a couple of minutes. Valley and heaven cause a restart after 4-6 minutes. I kept my pc running 5 days in a row non stop only just avoiding the aforementioned programs and i had no restarts... So i began testing my ram, hdd and cpu and they all were fine. The only two remaining suspects are my gpu and psu. Also i used Open Hardware Monitor to see if it was a heating problem but the restarts occur when my gpu(67-68 degrees) and cpu(46-52 degrees) so thats not the issue. I have clean intalled win 10 x64 jumped back on some video drivers, flashed my bios, made sure the sound drivers are not in some conflict, tried a few different power sockets around the house and changed my surge protector and reverted back to the latest drivers + cleaned my pc of dust. All the programs i mentioned before ran with no problems on this pc until 2 month ago. Here are my specs: msi gtx 970 4g
sata3 7.2k 1 tb
2x8gb ddr3 1600 mhz
intel i7 4790
coolmaster g650m.
This issue is starting to give me headaches, so i decided to throw in the towel and ask for help. I'd really appreciate some insights, what do you guys think ?
 
Solution
You've done good basic troubleshooting so far. Take the graphics card out and test in another system. If it works there, try another PSU in your PC. If both of these check out, then the motherboard is probably at fault.
