Just upgraded to W10 from 8.1 and I'm getting apparently random Freezes without BSOD and sometimes BSOD Machine Check Exception.
The problem already happened 3-4 times on Windows 8.1. Somehow I thought it could be related to CPU temp, so I opened up the case and cleaned it. No significant dirt found...
I also read somewhere that it could be related to using the laptop with the battery. So, I removed the battery and it seams to be fine for a while.
