Could it be possible that the standard HP Elitedesk 500w just doesn’t have the oomph to run the Mllse rx580 sp2048 8gb, the pc just closes down when it hits a stressful gpu bit in a game. Bought a new 650 psu then someone suggested flashing the gpu, surely a full system shut down would point more to the psu, which may be a few years old.? 🤔
