Mouse will move but not click
Hello. My parents are having computer problems and since i like to play computer games i am apparently the "go to guy" for computer problems... even though i don't really know that much about computers.
It wont click on anything but the mouse will move. Tried another mouse to see if the problem was with the mouse. The other mouse has the same problem. It moves but will not click. I can't get the computer to turn on since it gets the windows user login page and i cant click on a user.
So instead i did what i do know how to do and opened it up and cleaned the one case fan it has and also the cpu fan and heatsink and i applied new thermal paste. And if i can get it to turn on i can turn off useless startup programs and run some programs like ccleaner and spybot to clean it up but that's about the extent of my knowledge.
I'm dumbfounded as to what is preventing mice from clicking and cannot figure out how to fix it. Google search yields me nothing useful, or atleast not so far.
