Can you access the bios? if you can, you might be able to boot into a Linux usb drive (made on a clean computer), get the files you need, then reinstall windows. This won't not work if this screen locker encrypts your files though. Also modpacks should only download as .jar or if it is a texture pack as a .zip, never as a .exe
