So i recently upgraded my pc to sell to my brother. I added an ssd alongside a 1tb hdd and upgraded to windows 10with a liscence my college gave me. I had some,issues with the game,counterstrike freezing so last resort i decided to fully reset because i had no data to lose. No it has completely frozen,at 3%. What should i do? I cant reinstall windows becuase it was an upgrade key,and itis completely frozen. Any tips that will help this,not become a useless brick would be appreciated
