how can i fix corrupted system files without cmd (windows 8.1)

[fintagenewb]

I cannot open cmd as admin because i (for some reason) cannot open file explorer, any help on either subject would be appreciated.

If files are corrupt no point trying to fix it. It'll probably get worse

Replace the hdd
