so that started happening 2 days ago out of the blue. To start with when I opened my pc the mouse wasn't working, I tried to re connect it but it didn't work neither and I had to restart pc so it could work .Then while I was playing a game my pc froze and ctrl alt delete didn't work neither so I restarted it and everything was ok till it crashed again and I always have to restart pc when it crashes . As I said before that started happening 2 days ago it has never happened before ( I used to freeze sometimes in the past not a big freeze just a bit fps drop but it was working smoothly but now I have to restart to work again )
