My Corsair Pro A200 is out of warranty, its 2 years old. It keeps on having random restarts and on my event log its Critical Error 41 . I thought it was power supply problem so here are the things did so far:

1. change power cable
2. went to repair shop and changed power supply (even attached now to ups backup power to regulate and make sure my power from house is ok)
3. did all the youtube videos regarding power settings etc etc etc.
4. reset windows 11
5. reset to windows 10
6. Changed NVME Boot drive hardware
7. Removed Secondary SSD

None of this worked, it still gives me Critical error 41. It does this either if theres a load or just idling. No common pattern.

Running out of ideas. Anyone?

Problem is this machine is not designed to be upgradable, so I dont know how to proceed. This is the most disappointing machine i have /had so far.
