PC shutdown/restart issue

[Flafty]

Within the last week, CoH has begun doing something that causes my PC to shut down and reboot itself without warning if I play for more than 10 to 20 minutes at a time. At first, this was reported as my ASUS motherboard using its "power surge protection" feature, but the problem has persisted even after disabling that feature. No other program that I run on my PC seems to do this. Monitoring my power supply for voltage output hasn't revealed any unusual activity, so I don't believe its my power supply. My BIOS and all my drivers are currently up-to-date. Any suggestions on what to try next?

Check and/or clean your fans and heat sinks.

Checked and that doesn't appear to be the issue. Running the game only seems to cap out the internal temperatures at about 50 C

Power Surge != Heat.  Does your BIOS or EFI have a temperature limiter running that halts the system if it exceeds a threshold?

 

I don't advise turning that up past 70 degrees celsius myself, but figuring out why the overheating is occurring and solving the issue would probably be more beneficial.

Running some stress tests using CPU-Z gave me a maximum temperature of 67C, so I don't think heat is the issue. Additional testing leads me to believe that its either my power supply going bad, or my motherboard going on the fritz

Just clearing another possibility:

 

Are all the capacitors on your equipment healthy?  No signs of swelling or leaking including dry, crusted leaks?  While I usually hear of these causing sudden shut down through general usage on the computer, I can see a scenario where one or two programs stress a bad capacitor just right to cause the shutdown.  Of course, if you're playing other games that cause greater stress, but without result, that may negate the argument.

 

Do you have access to another power supply?  That is, can you borrow one of equal or greater power for a day from a friend?  Swapping it and testing might identify or eliminate the suspected part.

 

Is there anything else running in the background, like Steam client, if you routinely play other games? I point Steam out because I recently had some sudden power-off problems on my 7-year-old rig, and traced it to Steam running in the background even when I was not using a Steam-based game.  I've made sure it was completely powered off, and haven't had a problem since.  Some reading on the web revealed that mine was not the only computer affected by Steam this way, and it might be related to older equipment.  I've got a new rig to build Thanksgiving weekend.

How old is this system?
