Randomly Crashing KernelPower 41

[Pawelelele123]

My computer is having random crashes, no bsod, no minidump files. It just restarts, sometimes with windows fixing itself, sometimes without it. I just changed my RAM because it was faulty, I took my father's RAM that worked fine in his computer. I always had weird history with Kernel Power 41, last time I bought new computer just because of it and now its back. My drivers are updated. I thought it might be related maybe to my power socket so I bought UPS but it still happens. It happens very randomly, I can use my computer without it for a week and then I get it 3 days in a row. Now I used it for months without crashes and last month it started again.  What can I do with it?
