As some of you know I have had some serious issues with my computer since December 2013. I do plan on getting a new rig in a few months, but not being able to play ANY games until then just doesn't sit well with me. So I am here to ask of your help concerning my computer.  
My rig doesn't recognize my keyboard when I try to type or play any games. However, it recognizes the hotkeys, like opening windows media player etc. I cannot connect to the internet on my rig for some reason. I am unsure of what caused my computer the inability to connect to the internet or my keyboard to stop working, however, it started right after my dad did a system restore. He didn't give an explanation as to why he gave a system restore, but all I know is after he did, these problems surfaced.
I went into device manager and seen that the keyboard drivers are either missing or corrupted. I went into troubleshooting and it said to uninstall, so I did. I plug them back in to reinstall and it says I need the internet, which I am unable to connect to for some reason. When I plug the keyboard/mouse back in the system recognizes it's a keyboard and mouse, however the drivers are still "missing or corrupted".  I went to microsoft.com/logitech.com to get driver updates for these components, using a thumb-drive to take it from one computer to the other, however nothing worked.
I blindly went into the BIOs and simply looked at everything, not noticing anything that stood out. (I am a rookie so that doesn't mean much  

 ).
If it helps here is a DxDiag.

Motherboard is an Asus P5N-D
I would really like to get back to flying, even if it is with crappy graphics. Any help would be appreciated.
