I've been banging my head off the desk recently trying to troubleshoot this build, hopefully one of the more experienced PC builders can help here.
Its is my first custom build since the Phenom II X4 launch days so i'm not 100% sure what i've missed. The PC barring the GPU is all new components and passed stress tests (AIDA, FurMark) without blinking but now I've started having random crashes with different Artefacts on the screen ranging from Going Orange, checkerboard and just Off>Reboot. Sometimes it then refuses to boot until its been fully powered off at the wall for about 10 minutes, other times is just boots back into windows.
Troubleshooting done so far:
PassMark 3D - Scores good and in expected ranges
AIDA64 - Scores good, no crashes
FurMark - No crashes
Win10 Memory Diag - OK.
Nvidia Driver update
Windows 10 Latest updates rollback.
All PSU Connections re-seated
Given this only seems to be after playing a game or the system being on for a while, i'm suspecting a Overheating issue or a bad power supply.

What consistently causes a crash:
Leaving it on overnight running a download manager
Running games: Two Point hospital 99% of the time triggers a crash on exiting the game, TransportFever2 is intermittent.
