Sorry to hear about the crash. That is painful to go through.
Look for inpact damage... hairline cracks... little pieces broken off... if not too badly damaged then you could get lucky and find that parts were just knocked loose, and simply need a removal and reseating.
If you are skilled with tools, remove the keyboard and bezel, and all the ports with screws holding things closed. Remove and reinstall everything... sometimes you get lucky.
Of if you have a friend or a neighbor who likes to work on computers get them to partiallly disassemble and reassemble everything...
Look for impact damage around sockets, hinges... look carefully for separation of components...
It is likely that you will need to replace the hard drive, or remove and reinstall software. You can put the drive into an external USB enclosure, to drag and drop valuable data to another computer. Then run the original Windows software to reformat and reinstall a clean version. Sometimes that is all it needs.
But also be aware that the problem can become more troublesome unless you get into repair mode... You can lose data, or have components fail.
Tell us more about the computer... by brand, model, and age... how far it dropped, and what immovable object(s) did it hit.
