You know, one time this happened to me, it turned out that the wiring on the reset button on the case had shorted. Just saying.
Also, you need something that can actually read your CPU temps, because that's another factor to consider.

RealTemp should do the trick, failing that the motherboard should have a util made by the maker for that.

Checking for short circuits isn't something I'm familiar with :o

Yesterday I ran GPU-Z (which comes with Furmark) which logged my GPU temperatures to a file. I had a short race and the temp got up to 75 with no problems. I had another race shortly afterwards and I did get a restart. I checked the file but the max was only 77.
I've run memtest86 from a USB stick. No errors were found but I did get a message about RAM possibly being vulnerable to high frequency row hammer bit flips. I have no idea what that is, but a brief search suggests it's unlikely to be the cause of my problems.
I've downloaded RealTemp. Since I'm doing full screen things its file log feature will be useful.

In the interests of science I played a computer game. A couple of twenty minute races in rFactor 2, plus a watching a replay, and this is the graph of temps taken every 5 seconds:

Here is what I'm thinking:
Don't be the motherboard.
Don't be the motherboard.
Don't be the motherboard.
Don't be the motherboard.
Don't be the motherboard.
Don't be the motherboard.
Don't be the motherboard.
Don't be the motherboard.
But look at the box:

It can't be the motherboard because it's military class! 4!
So I'm hoping it's the PSU because that's the oldest thing and I want a modular replacement to remove the clutter :cheeky:

Have nothing useful to offer ... but your message piqued my interest. Never heard of that thing - interesting vulnerability (details: (

In theory, it could be the problem (fundamentally bad memory that gets inadvertently tripped in certain conditions). However, quite unlikely in your case afaics.

Bad RAM usually results in freezing or a BSOD, not a hard reset. Not saying it's impossible, but that hasn't happened to me.
Over to biker to help with checking the PSU... you'll need a multimeter for that, though.

That graph is for my processor. The graphics card got to the high 70s. I ran memtest86 for 3 passes, and just under 5 hours. No errors were found.
On the subject of PSU testers, I've come across some comments saying they're only useful for making sure a PSU is functional, but not for checking if it's okay under heavy load. Do you think otherwise?

I decided to take a chance with a new power supply. I wanted to get rid of the exess cables anyway, so I got this:
(
http://www.amazon.co.uk/dp/B00ALK3QRS/?tag=xov-uk-21)
I installed it and ran rFactor2 with no restarting. I also got a new case with more space inside and a cable management setup. That makes a significant difference to the temperatures. In Furmark 3D the card got into the mid 90s (C), now it's mid-high 70s. In rF2 it was the mid 60s.
BUT..... I'm now getting an annoying buzzing sound from the card! I don't think it's coil whine - I got that when I first ran rF2 because the menus were allowing the FPS to go through the roof, and fixed it with a config file setting. This is in game and it's lower pitched. I could cope if it were just rF2 because the engine noises might mask it, but I can also hear it in the Dark Mod. I've tried limiting the frame rate to 60 but it doesn't help.
Bugger.
