My USB keyboard suddenly started misbehaving and doesn't revert to its original function. Please help

I was typing something online and suddenly some keys in the first row QWERTYUIOP started misbehaving. Keys "Q,W,E,R,U,I,O,P" when pressed was typing Q1, W2, E3, R4, U7, I8 etc. I got confused as it was functioning perfectly till then and all of a sudden it started functioning improperly. And then, I tried unplugging the keyboard and plugging it in a different port, the problem still persisted. I tried uninstalling the USB Composite device driver and installing it again. It still didnt work. I tried restarting the system, no use.

To check whether it's the driver problem or keyboard problem, i tried using it in my friend's laptop, it still gave the same outputs when those keys were pressed. 

I'm not sure whether I have to discard that USB Keyboard and buy a new one or find a troubleshooter. 

Please help me out with a working troubleshooter.
