Sometimes bad/unrecognised USB devices have a habit of stopping the rest of the USB hardware not to be seen.
But while I was snooping, I realized that the keyboard is not a USB keyboard, and it does work at login. The mouse is still a USB though. Still, I need a mouse to get past a pop-up upon login.
For now, I'm just running a pendrive linux distro. The problem lies with Windows (I think it's in the registry files). My mom can hardly tell the difference, and after spending hours already on it today, I'll probably just call up an IT friend of mine to come and see what he can do. Thanks for trying though. I'll update this with what the bug was after it's fixed.

Since you've mentioned that you're running a Linux install, you can try using AVG Linux version to scan your hard drives to see what's going on in there. Chances are it is a few screwed up DLL files, and if that's the case, then there's no option but to reinstall good ol' Windows. If you're a student, you can probably get a free copy of Windows 7 Pro from your college as an ISO (either that or it's exclusive for Foothill College).
What kind of pop-up?
And it is very unusual to lose all keyboard and mouse functions, especially now that you informed us the keyboard is probably PS2 connection.
Before booting into windows, press F8 after the BIOS screen to get a set of options, choose safe mode and try there..
If the mouse and keyboard works in safe mode it could be a virus or something went wrong with accessibility settings which can be changed in safe mode through the control panel.
tl;dr get Kaspersky Internet Suite. Fry's often gives out a rebate to get it for free, so it's a hella good deal.
[and yes I say 'hella'. I live in California. Get over it.]
He said he tried booting into Windows with Safe mode and VGA mode already.
