When playing games (under load) the PC will operate as normal for a short while, and then all the monitors cut to black, something makes a single click noise, and every fan in the PC goes to 100%, I can still hear the audio, and you have to turn the PC off via the power supply switch.
Sometimes it can take 20-40mins to go black, sometimes it can take 20seconds, it varies.
What I have tried and had no success with:
Updating BIOS and all other drivers (chipset etc…)
Using DDU to remove the GPU driver and then install the latest
Cinebench CPU test (didn’t cause a crash)
Uninstalled GameInput Service, Reinstalled and set startup to automatic
Downloaded Microsoft .NET framework and Microsoft Visual C++
Disabled Windows game bar and game mode
Individually testing each ram stick, and lowering the ram frequency
