Issue: When I play demanding games such as RDR2 or Warzone 2.0, display will suddenly turn off and the CPU debug light will also turn on on the motherboard. The motherboard lights and fans are still on; it looks as if the pc is running. Power switch on case does not work, so I have to manually turn power off from the PSU to turn pc off.
When did issue show up: I recently upgraded pretty much my whole pc (cpu,gpu,psu,2 more ram sticks) and all was fine. I realised that I powered my GPU (rx 6800XT) using daisy chains, and read that you should power them separately. Issue showed up as soon as I used two separate PCI cables to power my GPU.
Extra details: Undervolting my GPU seems to massively help (only no displayed once in the last week while playing RDO, all other games were fine) and undervolting both my cpu and gpu seems to resolve the issue entirely. I initially thought my PSU was faulty, so I bought another one (went from RM850 to RM750) and issue sill persisted. No overclocking on any components, RAM runs on 2666 Mhz.
