|mmm... Likely you have realised the benefit and wisdom of ensuring all your personal "stuff" was saved (copied/duplicated) elsewhere at all times; typically to DVD and/or even an external HD. That way if "anything" causes a loss of "stuff on eh system as is (was...) all that personal "stuff" is secure and safe elsewhere...|
Back to your wifi problem.
Is there a wifi adapter installed; be it a plug-in card (internally) or via usb-adapter (aka a dongle - looks like an oversized usb stick).
If so are the drivers installed for whichever it is?
Go to Control-panel\system - as per this simple "how to":
There (as possibly you already know) you can inspect all hardware installed. See if the network tab has anything listed - and of course any wifi adapter will be there - under whatever name the device is called... If it's installed correctly there will be no yellow exclamation marks etc against it. If it 's not correctly installed there will be a yellow mark next to it.
If you right click on each network adapter/device you will see a dialogue box etc. which allows you to view it's status - drivers etc. and to update drivers if needs-be (or even install them if not present already).
So clarify what your wifi adapter is - make/model; are the drivers correctly installed. Is the device (if correctly installed) actually enabled (as in switched on) Typically there is an icon bottom left tray area that indicates if the wifi connection is enabled/active (or not). If the icon is present right click on it and see what says/offers as well; possibly the device is simply switched off - and thus you can switch it on via that icon?
Also confirm that you do have a router that allows wifi - which by the sound of your comments overall you do have...; what make/model is it?
