Random Reboots While playing games

Hello guys im having a problem for the last 2-3 weeks my pc reboots when im playing games

My Specs:
Cpu: AMD FX 8350
Ram: Vengeance 2x4gb CMZ4GX3M1A1600C9B
Motherboard: Gigabyte GA-970A-D3 (rev 1.4) Latest Bios
Graphics Card: EVGA GeForce GTX 970 FTW+ GAMING ACX 2.0+
SSD: Kingston SSDNow V300 120gb
HDD: Seagate 1tb if i remember correctly
PSU: Thermaltake Smart SE 630
CPU COOLER: Arctic Liquid Freezer 240

No its not and overheating problem I clean my computer every month.
I have tried prime95 on power consumption option computer does not shut's down tried using all the memory pc still ok tried using all of the cpu so it was going to overheat again never did shut down or reboot. I have also used FurMark to Stress my Graphics Card and it didn't shut down or reboot.
I have also tried disassembling my pc and re-assembled it the problem its yet to be fixed.The only thing that fixed the problem temporarily is changing the power cable of the PSU to a new one because when i applied this PSU to my computer i didnt change it with the new one.
By the way i also reinstalled win 10 just in case it was the problem, i will be waiting for your opinions.

This is sadly one of those usual builds

You see in the shop. You nod as the client tells you it's not heat then you clean and change all the heatsink compound and hope it clears up be what's next is usually are new parts. I've had to change motherboards, RAM, PSU, video cards and drives so anyone that tells you it's this, just is new.

-> However if only during games, I have traced it to game issues. One of my favorites was anti aliasing ( http://www.tested.com/tech/pcs/1194-how-to-choose-the-right-anti-aliasing-mode-for-your-gpu/ ) The PC would reboot in game on 16x but not when it was off. The owner had lost a year trying to fix it.

What do you think it is?

Did share a Web Speccy for others to read? Would you?

Those option dont look as a solution too me but thank you. I hope you do have some other ideas on what might be going on.

Why not tell us

In reply to: :/

How old this computer is ? Even though you clean it every month , you haven't told us that you have applied new thermal paste on ALL heat sinks.

The computer was made by me in the beginning it was just a computer so i can use for work and other thing, then when i had the money i started upgrading it. And yes i do change the thermal paste on the Cpu every time i clean it not in the graphics card because i will loose warranty.
CPU temp are from 1-30 C Max what ever i do. The graphics card goes from 40 c up to 71c Max. and the moba TMPIN0 30c +5 when im doing things TMPIN1 22 maybe goes 30 when is getting used and TMPIN2 20 c up to 41c max. (used TMPIN cause thats how HWmonitor shows it for the moda dont know witch one is for south or north bridge and so on.)

Moba: About 6 years when i first build the computer
Cpu: Same
Ram: Same
Psu: Almost 2 years
Graphics Card: Almost 2 years
HDD: 3 years
SSD: 2 years
Cpu Cooler: 9 months

At 6 years....

In reply to: Ok

I've had to change motherboards as the electrolytic capacitors are gone. Random boots are common in old boards. Yes you can tinker with timing to eek by but the clients usually are back at the counter as they tuned it back to full speed.

This is why we try the fresh compound on all heatsinks (I mean ALL, not just the CPU and GPU) before we move to new boards.

No Speccy? It lets the forum members check for issues without you having to dig around.
PSU? Make, model? What we want to see here is a monster single rail unit.
