My issue is basically summed up in the title. The circumstances are quite odd, I believe, so please bear with me as I detail them at length.
A few hours ago, I was using my computer as usual, Windows 7. No new hardware or new software installed, and sudenly my system became partially unresponsive to my mouse. I rebooted, but the problem persisted.
Now, I know it's not the mouse's fault because I've already connected the mouse in a different USB port and the problem remains the same: the system still responds to the mouse clicks under certain circumstances. For example: when I turn the computer on, the task bar and the desktop icons are completely unresponsive to mouse clicks. However, if I ctrl+alt+del and open the task manager, the task bar will become responsive again, while the desktop icons will also become responsive but will act strangely: every time I left click on them, the options bar drops down, as if I had right clicked the icon. The system remains completely unresponsive to right button clicks.
Every software in my PC is also only partially responsive to mouse clicks, but, unlike the task bar, their situation does not improve with ctrl+alt+del. Let me talk about Google Chrome as an example:
Any page I visit is 100% responsive to my left button clicks and 100% unresponsive to my right button clicks. The browser's interface itself is 100% unresponsive to right clicks and only partially responsive to left clicks: I can click on the button to open a new tab and then close old tabs I have, but trying to click on an old tab to switch to it yields no results; Chrome detects the cursor when I hover it over the menu icon (the icon turns darker) but is unresponsive when I click on it; Chrome remains unresponsive if I try to select the url bar, etc.
I've already scanned for viruses, but Avast found nothing. Someone in the internet recommended Malware Bytes. I downloaded it as a free trial but the software is unresponsive to left mouse clicks, so it's just sitting here. Someone else also suggested interrupting the explorer.exe process and starting it again, but it didn't work for me.
Can anyone help me, please? Thanks in advance.
