Probably not.

I'm not sure if that can be done reliably, but I wouldn't jump to
conclusions, especially if the trouble only started after you
upgraded the CPU.

Try running Memtest86 to check the RAM didn't get damaged
accidentally. Linux probably won't be using as much RAM as Win10,
so it may not have reached the memory region that's faulty.

Did you try Safe Mode (assuming that's still around in Win10)?

All things are possible, but again it's unlikely.

Check the BIOS setting didn't get reset or set wrongly while you
were doing that, eg. RAM clock frequency.
