It is a weird problem. My one and only serial mouse was not working properly so I thought i could fix it mself and disassemble the mouse and sprayed it with a washing liquid. Then I let it dry and assemble it back. when I attached the mouse again nothing was changed and the mouse was still acting weird. However after 1 or two days It wasn't working at all!!!!! The most weird thing is that the pointer is not even shown. I thought installing windows again would solve the problem but the pointer is not even shown not even during the setup regardless It is 98 or 2000. So, I think it is a hardware type of problem but how can it be that the pointer is not shown at all!! i mean i still remember that even if you don't attach a mouse and start windows 98 setup, it will still show you a pointer but here it is different not even showing me the pointer!!! what's up with it?
By the way, by my mouse acting weird, I meant that it kept on right clicking by itself and the pointer was moving to the right side very rapidly. It use it to happen once in a while but it increased until I could not work at all and I have already told you the rest of the story above.
