Automatic use of up arrow key in pc

[AshKing15]

Hi guys, Actually my pc automatically presses the up arrow key in playing games like NFS Underground, GTA V, NFS Carbon and many other applications. I also tried detaching my keyboard from my pc but the problem still persists. So now I know my keyboard is not faulty here.
Will changing my windows help me ?
Or any other solution to the problem ?
Thank you in advance

My pc details are:
Windows 7 Ultimate 32bit
Intel E6700 Dual core 3.2ghz processor
Intel G41 express chipset 2gb ram

So guys what happened was In games like NFS Underground, FIFA 2007 and GTA San Andreas, I experience automatic use of up arrow key even if the keyboard is detached.
So, when I switched from Windows 7 32 bit to windows 10 64bit last Sunday and the problem was solved but today I experienced the same thing again.
Please Help
Thank you for any answers.

- windows 10 64bit isn't a good choice with only 2 G of memory.
- The mouse wheel does the same as the up arrow key. Try changing the mouse.

Thank you for the suggestion

What's the cheapest and easiest way to increase ram?

So, I tried the step above but no luck but I noticed one thing that when I unplugged my mouse before starting NFS Underground, the game crashed and reported that it had stopped working but when I plugged my mouse again the game launched and and then I unplugged the mouse again but it didn't work for me.

Replace the one you have with two sticks (4G+4G). Buy a little higher speed and lower latency than the original.
If you don't want to have memory problems, don't mix new with old.

I didn't say to unplug the mouse. I suggested to replace the mouse.

Okay but when there's no affect when unplugging the mouse will there be any change when the mouse is replaced
