This only started happening after I ran PC Reviver and went through the "Repair" process. Now nothing happens when I try to right click any icons on the taskbar, and I cannot open the Start menu with left click. Using Windows 10.
You can try the below fixes to make your Taskbar work without any problems.
Fix 1: Repopulate Taskbar via Command Prompt If your Taskbar is missing its icons and the tray at the bottom right is missing functionality like the clock, you might have to dip into the command interface to remedy your issue. First, use Windows key + X to open the Quick Link menu. From here, you can launch a Command Prompt with administrator credentials, which is required to open the Disk Image Servicing and Management (DISM) tool that we’ll be putting into action to make this fix.
Use the following code in the resulting prompt, and you should find that your Taskbar returns to its normal state: DISM /Online /Cleanup-Image /RestoreHealth
Fix 2: Use commands
Press Windows Key + R on your keyboard.
Key in PowerShell and hit Enter.
Right click on the PowerShell icon on the taskbar and select Run as Administrator.
Now paste the following command in the Administrator: Windows PowerShell window and press Enter key:
Fix 3: Check Your Drivers This is relatively broad advice that’s applicable to many PC problems, but it’s been proven to solve Taskbar strife for some users. Outdated drivers can cause all manner of issues, so updating standard drivers, like the graphics and audio drivers, is a good place to start if you’re at a loss as to what’s affecting your system.
Fix 4: Create a New User Account If you’ve tried everything else and still can’t manage to make your Taskbar behave as it should, try this method.
To create a new user account, open up the Settings app (Windows key + I) and navigate to Accounts > Family & Other Users. Under the Other Users section, select the option that reads Add someone else to this PC.
I kept getting the blue screen with Driver Power State Failure error message and then my computer would restart. I found your product and it did not happen any more. I just purchased an anti-virus (kaspersky) and now it is doing it again. It is so frustrating. My computer is only 6 months old. It is a Asus desktop.
