Even something as simple as a mouse button can fail. If the left mouse button is held down, does not respond consistently or accidentally double-clicks, this often indicates a hardware problem with the mouse. However, this could be a software problem.
This is probably a hardware problem. Review
In our experience, most problems with the left mouse button (or right mouse button) indicate a hardware failure. If the left mouse button does not work, reacts only occasionally and is accidentally "clicked" when dragging, clicking or double clicking, this is a good sign that something is wrong with the hardware in the left mouse button. Click the button itself.
There's an extremely simple way to check for hardware or software problems: unplug your current computer, plug it into another computer, and test the button with the left mouse button. If you have a wireless mouse, either connect the RF dongle to another computer or pair it with another computer via Bluetooth.
If the problem is similar when connecting the mouse to another computer, there is a hardware problem. If the mouse is working properly on another computer, there is a problem with the software configuration of your current computer.
You can also try to connect another mouse to your current PC. Does it have the same problem? If not, there is probably a hardware issue. If both mice have the same strange left-click problems, there is definitely a software problem with your PC.
There may also be a problem with a USB port on your system. If it's a wired mouse, connect your mouse to another USB port. If you have a wireless mouse with a USB dongle, slide the dongle to another USB port.
Note that some issues may be sporadic or sporadic, especially if the hardware is just down. The mouse button works very well in most cases and only turns off sometimes. Use the mouse long enough with another PC to see if it works properly.
Fixing a broken mouse
All mouse buttons will eventually fail if you use them enough. Mouse buttons are designed for a certain number of clicks. For example, the latest version of the popular DeathAdder Elite gaming mouse from Razer is designed for "up to 50 million clicks". A cheaper mouse can be designed for much fewer clicks. After that, the physical mechanism of the mouse button wears off and does not work properly anymore.
