Okay, so, my cursor can move, but occasionally, my cursor will be able to stop clicking, meaning I'll have to do Ctrl+Tab to move through programs. I'm on a Windows 7 laptop, 64-bit to be specific, and I'm using a Corsair M65 Pro RGB. Right now, my cursor can move, but won't click, and I can only click on the program I am using right now. Not on the toolbar, not on the Windows logo, not on any program, just Google Chrome right now. I really need some help right now, and this has been happening since, I believe, August.
First, take note of if this only happens in certain programs or not. If so, then the programs themselves may be the problem. If it only happens with the browser, certain sites may be interfering.
Also, you might want to check for updates to your drivers, including the Synaptics driver (if your device uses one).
Next try starting up the laptop in "Safe Mode" and see if it happens in there. If it works fine in there, then it isn't hardware.
How to enter "Safe Mode" when booting the computer.
In Windows 8 and 10...
As your computer restarts, press F8 (possibly a few times) to enter "Safe Mode"
a. Press the "F4" key to Enable "Safe Mode".
(The computer will then start in "Safe Mode" with a minimal set of drivers and services.)
b. Press the "F5" key to Enable "Safe Mode" with Networking.
( Once "Safe Mode" with Networking starts, Windows is in Safe Mode, with additional network and services for accessing the Internet and other computers on your network.)
c. Press the "F6" key to Enable "Safe Mode" with Command Prompt.
(In "Safe Mode" with "Command Prompt" starts Windows in Safe Mode, with a Command Prompt window instead of the Windows interface. This option is mostly only used by IT professionals.)
Now sign in to the computer with your account name and password. (If you have one set.) When you are finished troubleshooting, you can exit "Safe Mode" restarting your computer.
In Windows 7/Vista/XP...
1. Immediately after turning on the computer, or restarting it (usually after you hear your computer beep), tap the F8 key, repeatedly, in 1 second intervals.
2. The computer will then display hardware information and run a memory test.
3. Next the "Advanced Boot Options" menu will appear.
4. In the "Advanced Boot Options" menu use the arrow keys to select "Safe Mode" or "Safe Mode with Networking" and press ENTER.
If this does not help, and an external mouse works fine, then it may well be a hardware issue.
