Puzzle me this

I have a custom built computer dating to 2009. In the last year or so it has developed a very odd glitch. When playing GW2 it will occasionally self reboot. Playing certain areas of the game is worse than others. It did not happen in the early days of the game, I have been playing GW2 since Beta. It does this only when playing GW2 no other time. I have replaced video card, cpu cooler, and changed operating system to Windows 7. Every now and again on it's way to rebooting it will display the message, "Out of Range". Then I have to finish reboot by hand. Here is a Speccy display of system.

Currently I am thinking of replacing Motherboard/CPU as a cheaper way to correct it over buying a new system. It has also occurred to me to replace memory first. Dose anyone have a possible match in your history of trouble shooting computers?

TBH, sounds like a worm.

There was a clean install of the new OS, including a format of the disc.

Had a reboot problem on two separate machines. One it turned out to be a bad stick of memory. The other it was a laptop that I hadn't put completely back together. Once all the screws went in, it worked fine again.
