Okay, from the tests everything seem to be fine and I haven't encountered the issue yet. But I will try to test again and report the results
Test the PC by gaming with just the one screen hooked up and if all good, shutdown the PC, attach the second screen, power up and again test, use the same game for both tests and to begin with any gaming should be done offline as online gaming in itself can have all sorts of problems on its own.
If you do not have any games that you play offline let us know and we will provide you with a means of doing the tests.
Tip, while the PC is running stable you should create a new system restore point and likewise if you intend to install any new program/s, update any software ( Including Windows and Defender ) if you make any changes to system settings keep a written note of the original settings first, these couple of things are your basic safety net.
My PC lasted a few hours of gameplay before this issue reoccurring.
I did not install anything new or do anything significant, such as changing the settings of my system or bios.
The game seemed to run fine for two hours but crashed after that. During the crash, I also noticed that my PC was a bit hot, i
What happened exactly.
Software such as Windows can crash and when it does crash you get a BSOD and when enabled a crash dmp is generated, programs or games when they crash can on occasion close to the desktop but the computer will still be 100% functional.
Hardware failure such as a weak power supply and/or overheating are not software related and when a computer for example suddenly turns off, freezes or the screen goes black etc the behaviour should be described as the "computer shut down unexpectedly" or froze etc and not as having crashed as the latter implies a software issue as opposed to an obvious hardware issue when described properly.
Having the correct info means that helpers will not be looking for a software issue when the problem is clearly hardware related.
