Last year I've bought a new system, Z77A-G43 motherboard, i5-3570K CPU, 8 GB memory, Crucial M4 CT256 250GB SSD harddisk, Radeon HD 7800, running Windows 7 Professional (64-bit). All in all a very decent system. However, whenever I play a game (Diablo 3, Path of Exile) it is just a matter of time before the system crashes. Sometimes (not often) I can play a whole evening without a crash, sometimes it crashes every 5 minutes. It does not seem to coincide with what happens in the game. As it crashes, screen goes black, it generates a nasty hum on the speakers, and all I can do is to push the power button until it shuts off the power.
The PC ONLY CRASHES during gameplay. Whatever else I do, like editing videos, music, playing movies, etc, it never crashes.
What makes it hard, is that there is NO dump file whatsoever. Minidump settings are all validated, but no dump gets created.
And no, it's not overclocked, BIOS is at standard settings. CPU, GPU, Power supply & cooling all seems to be in good order. CPU temperature hardly ever gets above 50 Celsius. Avg temperature of the MB is 38 Celsius.
There's no virus, no trojan. System is clean and well defended (Comodo Internet Security, HitmanPro), behind a physical firewall.
What have I tried:
- about a dozen different drivers for the video card
- reinstalled windows
- searched for crash dump files (used WhoCrashed, Debug), but there are no dump files to be found
- stress tested the video card to see if it either crashes or becomes too hot (nope)
- stress tested the power supply (left it on for a night)
- stress tested the memory, checked for invalid adresses
- stress tested the whole system
Used tools like WhoCrashed, Windows Performance Toolkit, Debug, FurMark, SystemStabilityTester, MemChecker.
I really don't know what to do next, other than buying a new PC. Any ideas?

, in all different modes. Currently running without CCC. CPU is cooled with a Zalman cooler. Gauging temperatures with standard MSI tools (came with MB) and with CPUID HWMonitor. Airflow is fine, system is clean (no dust). Running bare didn't change anything, other than making me feel insecure
