Try it on another system. If it doe snot work at the same time on any system, need to replace it.

Hey man thanks for the response and I am sorry that I am replying you so late.....

So I just did what you asked me to do and when I played with it on my friend's PC it was working very well.....and I was shocked then I came back home and I tried to play it on my PC and it was working fine again(I know it's shocking)

I don't know what the problem was or is but I think it might just happen again....and thank you again for the response....

I advise you sometimes to clean your keyboard, then in the future there will be less problems with it

is there any other problem other than this ? like a problem in my motherboard ?
