Well, if everything is so serious. Then: 1. Full overflow of connectors. 2. If it does not help, removing the motherboard and examining for cracks or a leaking capacitor, checking the carbonization of the contacts of the south bridge or other terristors. 3. Replacing the power supply unit with a more powerful one. 4. Excluding items 2 and 3, sending the motherboard and power supply to service centers ... No software tests will help here, since the problem is clearly not in the software. There is no point in reinstalling Windows if there is an antivirus or HijackThis did not find anything. By the way, if you didn't use the latter, then it also makes sense.
PS True, the problem can be solved differently ... It also happened like this: everyone, guys, the problem is solved. I removed the magnet for the counters of cold and hot water from the table)) .. Or in the toy I changed the DRM crack for another (as an option).

The first (optimal) reason is software, or a Trojan script that reboots.
You say the problem appeared ... about a month ago ... after the Game, Max is new ...
Roll back the system, demolish the game, look for Trojans not with your antivirus (he may not notice), but Dr.WebCureit (or a similar scanner ).
The second reason is iron. I also sin on BP.
Turn off all case coolers, DWD-RW, USB (gamepad, webcam, etc.) - the load on the power supply will decrease. Try swapping with a friend for one day of BP (for testing). Your power supply unit is 650W, but in my shed ... it is written, and there the firewood is lying. The declared power may be higher than the actually given out, and the conductors may "lose ground" over time.
And the third option is the motherboard. But here you can't do without a service center.
PS Reset BIOS to default (you never know what you have lured there).

Removed the magnet for cold and hot water meters from the table))
Even so? Is this a Skolkovo development? )))
It is quite possible that the power supply unit is to blame, you need to monitor the spout when starting heavy toys, or even arrange a stress test, OSST to help. If the temperatures are in order, then it's too early to sin on the rest of the components, until the power supply has been checked.

Unsubscribe, please - how will the matter end.
When there is a question, the answer is interesting.
Perhaps the game requires too much power, the computer cannot transfer everything and because of this it is cut out.

How did the investigation end? Who killed the old woman? Where is Happy End?)))
