Can't boot windows after it worked fine for a day after reinstall.

(Writing this on a phone)
So I was using my computer just fine one day though I had noticed it running a bit slower
Than usually.
Next day when I boot it up I get a black screen where windows runs some kind of repair on the registry.
After that it goes to the windows login and I could a sees windows it was super slow and would not start any programs without freezing so I reinstalled windows 7 and after it worked fine though I had to look for some missing drivers.
Day after I boot it up again and get startup repair that states it can not fix the problem.
This is the error message:
Startuprepairoffline

So after trying to fix it by disconnecting external devices which only was my keyboard, mouse and screen. It still did not work so I reinstalled windows again.
It worked for the entire day again with no problem. Started it this morning and logged in it was missing audio drivers, restarted the computer and now it will not boot.

pretty sure it was my hard drive that was broken switched it out to another one and now I haven't had to reinstall again.
