PC rebooting without BSOD while gaming.

My PC is having this problem for about 8 months now. At first the reboots were less but recently they are more frequent.
I recently cleaned the motherboard (found some moisture on it). This reduced the frequency of the reboots but has not totally removed it. By using AIDA extreme's system stability test, I found out that the pc is shutting down (rebooting) after CPU reaches around 86c meanwhile GPU is around 80c which according to me is high but should not be shutting down the system. I did the memtest with both sticks on and I did fine for 4 hours with no error.
My specs:

  • gigabyte H81M-S
    Zotac gtx 950
    Core i3 4130T
    Rams: Kingston HyperX Fury 8gb and some Kingston 4gb which came initially with PC before I customised it 2 years back.
    Corsair vs450
The CPU voltages are fine and also there is no CPU throttling. It normally happens within 5 to 120m of playing Assassin's Creed Syndicate and if I go straight to playing game after a restart it reboots even faster.
Since the reboots are less frequent after cleaning I really don't think it is the PSU. Can anybody please tell me what should I do?
I found many threads with similar problems but none had temps as I high as I have, is that a problem?
I am really frustrated because I am a college student on a limited budget and cannot afford to have replacements available so readily!
I have underclocked the CPU but the problem still stands (sigh)...

I read your answer and installed a fan. Since then, the cpu temp never goes above 64c. But my pc is still rebooting without any bsod and while monitoring the gpu temp, I found out that this happens when the temp goes above 70c. Is 70c still high for gpu or there is some more problem elsewhere?

P.S: Thank you so much for replying!

Now it never goes above 64c after installing an extra fan but my original problem is still not solved. I live in a humid region with temperature is always above 30c (reaches 40c sometimes). I think that's why there was some moisture on the motherboard!
 


Is the computer connected to a surge protector?

Yes and the only thing connected except the monitor and the CPU is my wifi router.
Also one more thing. I played FIFA 16 ome days back; the CPU and GPU max temps were 60c and 51c respectively (and they remained at these temps normally throughout the whole gameplay). Though these are low temps comparably; my pc rebooted after about 2hrs. Another day it rebooted after 5 hrs. I am not sure what should I blame now for this!...Please help!

I have other PCs (though not so powerful as the one having this problem!) and none of those have this problem. If none of the other solution works I will definitely try this one. I hope this is not the problem though!:lol:
 


Yeah, there's been these phantom reboots throughout the forums for whoever uses Windows 10. No idea what's going on.
