My computer broke

Hello,
I have a problem with my computer. It's battery broke down a while ago and after that I often turned it off by plugging it out (due to impatience) and then the computer shut down immediately. Not so long ago I did this again but now when I turn on my computer the windows sign comes while the computer loads but then the computer sends me back to a black screen with options like turning the windows on normally or turning it on with the last good configuration that worked or safe mode etc. It stands that it's doing this because it didn't turn on successfully and it may be because of sotware or hardware changes or because it restarted or got shut down during some proccess or something (which is probably the case with me). Now I've tried to turn it on with all the options given but it always sends me back to this screen. I really need it fixed and is there anyway for me to do it without taking it to a store?
