My computer cursor won’t click on anything but it moves just fine , this is a windows ten I bought three years ago by the way. Anyone know why?

I noticed when I have the problem a small white dot appears over the taskbar in the middle of the screen. After doing a CTRL-ALT-DELETE and clicking twice (click once does nothing) within the dialog box, the white dot fades away and the mouse/cursor functionality returns to normal. This seems to happen at random, and I can't seem to find the offending process.

personally i had steam beta doing something similar, you can try running a software HijackThis which will give a log of processes for troubleshooting

screenshots also could help

Hi all, in my case it was worn out contacts on the mouse, so a mechanical problem, not a software problem. HTH

I have recently been having this issue. I thought it was related to a mouse I spilled on, but the non-clicking issue is all of the devices. What I learned, though it is not ideal, is I go to force a reboot, (CTRK+ALT+DEL), the lock/sign out/reboot etc screen pops up and suddenly I can click again. I hit ESC and go back to working. Not a permanent fix, but it is slightly quicker. It also indicates to me it is a OS/App/driver issue, not hardware. I still cannot figure it out.

i have a exact same problem with my Logitech MX 518 and i tried with different pc and laptop with win 10 and 11 ,, the weird thing is, if i use usb to ps2 then conect the mouse with ps2 the problem is solved!! but no lock with usb
