help needed! mouse/touch pad can moves but can't click?

I've been having the problem of mouse/touch pad being able to move but somehow, i just can't click on anything with my laptop a few days ago. It just feels like everything is in the "not responding" state when using the mouse and also the touch pad but then everything seems just fine when I use my keyboard to operate them. I've tried formatting my laptop myself and also sent it to a shop to do it, but nothing has changed

And also, ever since this problem occur, my laptop seems to be slowing down no matter is shutting it down or running a program.

I've no idea why all this could happen, the only things that I use my laptop for these few days is for Facebook and some online streaming on YouTube, and all of a sudden this sh*t happen.

Can anyone mind giving me some ideas on what is going on with my laptop? Your help is kindly appreciated! :)

Thank you

Hi, thanks for your suggestion, I've tried removing my mouse and leaving only just my touch pad and so far it works without showing me that problem, but is there any other methods to recommend? cause if in this case i can'y use my mouse @@

And can i know what usually causes this problem?

Thanks =)

Erm.. As a add on, i've tried connecting my friend's mouse on to my laptop.. The same problem still occurs and it get even worst! ><

For the 1st time i did, once i remove my mouse, the problem seems to be solve. However after i tried using my friend's mouse, the problem still stays even i've removed the mouse ><

Is this my laptop hardware problem or is it just a system error? @@

hi, just wanna ask.. i tried restart my laptop with my mouse being unplugged a few hours ago, and it seems the "can't click" problem is solved.. So, now the question is, is it impossible for me to use my mouse from now on? and what cause this problem? @@

Thanks for your help again =)
