Hi I have a Desktop MEDION ERAZER P66078 (MD 34629) UK, MSN: 1002 3317, PC System D098 UK This unit has a GTX1650 in it and I am running windows 11. It is out of warranty by 8 months It has started to shut down unexpectedly and it is doing more frequently. The computer will be running and then all power goes off. It will not restart after this. To get it to restart you have to physically unplug the power cable and wait a few seconds, plug it back in and it powers up. I first noticed on steam games so I thought it was GPU overheat. I have been monitoring system and GPU temps and making sure there is sufficient fan cooling applied. The system has become more unstable and just shuts down when using teams or other simple desktop apps. I am not seeing GPU overheat triggering this. I have replaced the PSU with a new higher power PSU as all signs were pointing to a faulty PSU. Clearly that is not the problem. What else can cause a PC to stop completely and suddenly as if the power was switched off. What else can I try to isolate the issue? I dont have another GPU or another desktop machine to go swapping bits. Hoping for some pointers. Thanks
