My mac wont run any software

I have a mac that has both macos and windows, and it was working perfectly fine until yesterday. The battery died, and when It finally turned on, the windows software cant get past the "automatic repair" screen, anything i tried just turns off and starts again in this screen. The macos software is no better, just starts up and turns off in the middle of the loading screen. Im sorry if its difficult to read english its not my first language. Can someone help me, i really need this laptop!
