Shut down as you describe is usually due to two causes. Overloaded power supply shuts down to protect itself or overheating CPU.
Have you monitored the temperature for the CPU? For example with no load speccy is showing me
Intel Core i7 930 @ 2.80GHz 50 °C
Bloomfield 45nm Technology
That tells me it is time to pull the side and clean my CPU heatsink assembly. That will happen today. I just got the can. of air to do it.
Thanks to Sneakycyber for this
- Go to Piriform's website, and click the big button.
Next, click Download from Piriform.com (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version.
You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.
- After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.
- Once inside Speccy, it will look similar to this (with your computer's specifications, of course):
Now, at the top, click File > Publish Snapshot
You will see the following prompt:
Click Yes > then Copy to Clipboard

Congrats! You have just posted your specs!
Doing this will show temperatures for the CPU and a lot more useful information in one easy to read form.
How about doing this 10 minutes into the game and then stopping the game. You risk corrupting your windows with these shutdown events.
