I have a very strange error with the PC in my family. Here are the symptoms:
The system can be used just fine - opening programs, clicking on the windows button, ... Response times are as expected.
However, each time a popup from a local program opens (for example: when you exit a program and it wants to ask "are you sure to exit this program?") I do see the buttons within the popup, but I am unable to click on them. Means: I can move the mouse cursor over it, but when clicking the left mouse button, simply nothing happens. I can try to do so many times, but no effect. The only thing which still works with the popup is the X button (to close the popup) to top right corner (clicking to the "abort" or "no" button does not work either)
To cross check, I already changed my mouse, switched to another program via keyboard + using the mouse buttons afterwards, used the mouse (going to the task bar below) and switching the program there - always works just fine.
After a while, I figured out, that I am able to change the modal button of the popup by using the TAB key on the keyboard. I can also execute any operation from the popup then by using the "space" bar, which has the same effect as clicking.
The same effect also holds true, if I logon via a remote control tool (such as UltraVNC) from another client to this PC (then serving as host): There also navigating and triggering via keyboard works, but the mouse click command in that special case also is ignored. So, I think this rules out any physical/hardware-related root cause.
My current guess somewhere goes into the direction of the OS and/or the drivers. But where to start?
- Windows 10 Pro x64
- Asus Motherboard
- Geforce 210
- 1 TB HDD, Western Digital
- plus the usual stuff (keyboard, mouse, DVD reader)
Does anyone have a hint how to approach this kind of problem?
