Following from web_designer's code, rather than comparing against NULL, the function isset() should be used instead. PHP will not set a variable (or key in this case) unless data was sent using the POST method, therefore the if statament will evaluate to false if either of them is not set. If it still doesn't work, you should check the HTML form element to see if you set the method to "post". By default, the method for forms is "get", and so your code would never show the desired effect in such a case.

Did you just get this graphics card or did you have it for a long time and it is now showing signs of PCIE x2? And am i to assume that nothing else but the graphics card is taking up the x16 slot (you should verify this)? According these specifications, you only have one x16 slot (this is usually the one closest to the processor), the others being x1, and that you have a 300 watt power supply. Assuming you have the card in the x16 slot, then perhaps it is the case that your power supply cannot fully support all the hardware you have on there and the jumping around from x8 to x2 could be the motherboard trying to balance out the power to all parts. You could try purchasing a better power supply, or if you know someone with a better power supply, to test it out with theirs. If the better power supply does the trick, then it was the power supply. If it doesn't, then it is probably the motherboard. You can know it is the motherboard if you try to put a card that you know works in there and see if it shows similar signs.

1. Yes, any hard drive will do. It does not need to be of the same size unless you are planning to replace the internal one. However, do keep in mind that if you are replacing in the internal one, it has to be of the same connection unless the motherboard supports multiple connections (i.e. IDE, SATA, etc).(2) Steam allows you to back up and restore your games. I have not tried doing so for my games, but i would expect it to be a feature that allows you to copy your game ''database'' from one computer to the next without having to download everything again. As for any other random software, you may have to download them again.
