First off get a Usb stick. download your preferred windows iso file ( straight from microsofts website is adviced ).
there are apps to turn usb into windows installer . there is a official one on microsoft you can also download.
After everything is ready just take the files you want to save. ( if its low size just upload it to google drive you can download later. )
now you must get some idea of your pc parts. and get their drivers downloaded / ready in the usb.
or just go;
Windows Taskbar. -> Recovery -> first option on top will clear out the pc. not worth it in my opinion but it should help you.
