I've very rarely had an issue with Windows that wasn't fixed by replacing faulty/failing hardware. While not a hard rule, your issues sound exactly like that's the root cause. Time for a new motherboard or PSU. Most people just never realize it is failing, blame the OS. Everyone who has done deep stints into desktop Linux knows that's definitely not the case over there and Windows does a fantastic job at covering up hardware errors as much as it can, more than people realize.

Starting from my Commodore128 till today, other than that original Commodore, I haven't seen anything else as well-built as Windows. macOS & desktop Linux distros included. I hate to elevate one above the other but my honest opinion starting on desktops in 1986 that Windows is the most rock solid desktop OS out there today. Microsoft has to ensure it's the most battle tested by necessity, given that even back in 2011 it ran 1+ billion[0] devices. There's nothing else even in the same league for desktop operating systems when it comes to exposure, testing & fixes in the QA feedback loop. Even the big player, Ubuntu, doesn't come close.
