I didn't spill anything on my keyboard or anything like that, but all of a sudden I noticed my left and down arrow keys weren't responding. I tried the numlock, capslock, and Fn keys but it still doesn't work. The keys aren't stuck so I don't know what the problem is. Everything else works fine.

Re: Arrow key problem
If its a sensor problem under the keyboard, gently blowing under the key or hoovering the keyboard may bring results, but it may just be the driver, so go to my comuter icon, right click, properties, the hardware tab, device manager and go down the list to keyboard, click the '+' sign to reveal your keyboard make, right click on it and select uninstal.
Restart the notebook and the keyboard will be recognised again and the driver automatically installed.
If none of that works your problem may be more serious in the way of a faulty circuit under the board

This is going to sound really stupid, but if I was just having the exact same problem as you. I launched the Razer Synapse 2.0 program and save that my up key had a macro that did nothing. Once I changed that back to the default single up key function, it seems to be working fine.
If you want to use the buttons on your keyboard to adjust your volume, just hold the "Fn" button just to the left of the windows key, and then push the "up" arrow or "down" arrow. To be clear, those are just the main arrow keys, up will turn the volume up, and down will turn it down (of course).
Press the FN + F9 keys until the time and date appear on the LCD display.
press the FN + F10 keys to go into the Set Mode. Use the left or right arrow keys to select the hour. Change the hour by using the number keys on the keyboard or by up and down arrow keys Use the right arrow key to select the minutes and change the hour by
using the number keys or by using the up and down arrow
keys Press the right arrow key again to choose the 12-hour or 24-hour format with the up and down arrow keys. To change the date, use the right arrow key again and use the up and
down arrow to select the month. To change the day, use the right arrow
to select and the up and down arrows to change the day. When you are finished, press Enter on the keyboard to exit Set Mode.
