Windows 10: Keyboard shortcuts not working properly in Win10

I upgraded Win 8.1 to 10x64 on my Surface Pro 2. Now, when I press the End key in Explorer, nothing happens. I am not taken to the last file in the file view pane. In Excel 2010, Ctrl-Home minimizes my worksheet instead of taking me to Cell A1. I restored Win 8.1, but the problems remain, so I just went back again to 10. Thanks.

Computer Freezes

This is difficult to do since the computer is freezing. Any alternatives or shortcuts as the mouse and keyboard tasks are not working properly.

 

Hardware (Keyboard) Glitches/Issues

Basically, after I installed windows 10 after totally wiping windows 8 and upgrading to a fresh copy, I noticed that the windows key/control key didn't work for any of the new keyboard shortcuts that were added in Win10 (the original shortcuts worked just
fine), and if I tried to use the shortcuts, then my keys stopped "typing" so to speak. (The "i" key opened settings, the "n" key opened the notification center, the "a" key opened the action center, etc) After a bit, I discovered that if I used ctrl+alt_delet,
my keyboard would to back to being able to function properly in the sense that pressing a single key didn't act as a shortcut.

I have no idea if this makes any sense, so if clarification is needed, just ask

Don't know if my specs'll help, but here they are:

AMD fx 6300 (six core @ 3.5ghz)

8gb RAM (2x4) DDR3

64bit Win10

Radeon R9 270X 2GB twin "frozer"

Asus M5A97 R2.0 ATX AM3+ motherboard

Lastly, the keyboard is a TTESports Poseidon (blue switch)

Thanks in advance!
