Why did the Start button on my monitor stop working?

H. I have a Dell Optiplex 990 desktop computer running Windows 10 with two monitors և a wired mouse և keyboard. Although our home is wireless և we are running another laptop wirelessly և two HP printers, the Dell tower is connected to the Ethernet cable as it sits on my desk and the wireless router is right under the desk.

The Start button in the lower left corner of each monitor screen stopped working last week. Left-clicking և the menu screen no longer appears in the left pane of function bars և applications և other functions. (This still works on the laptop below.)

I’ve searched the internet for solutions to this “dead Windows Button” problem, but the suggested fixes range from ridiculous to sublime. Reboot does not help և Windows Update has been run several times without help. Troubleshooters did not help either. We have Kaspersky virus protection, և the full scan did not cause a problem.

A: The first thing I will try to do is restart Windows Explorer, which actually controls the Start button.

To do this, right-click on the system tray at the bottom of the screen և Launch Task Manager. Click the Processes tab, then scroll down until you see Windows Explorer. Check it, then click the Restart button in the window.

If this does not resolve the issue, I suggest using Windows System File Checker to troubleshoot. First open the Windows command prompt. If you can not access the Start button, you can search for “command line” in File Explorer. Right-click on it and select “Run as Administrator”.

When prompted, type “sfc / scannow”, then press Enter.

System File Checker will check for problems և replace any corrupted or missing files. The scan may take some time. If System File Checker makes any changes, you will want to reboot your computer.

H. Is there a way to find out what is causing the alarm sound on my computer? I’m running Windows 10 և my computer frequently sounds the alarm. (Sometimes sounds 5-10 times in a row for a few seconds). It’s the same noise it makes when something plugs in or (much less often) from a USB port. It also slows down the car by freezing it for one second at a time. This started a few months ago and is becoming more frequent.

I keep turning off everything connected to the car at once to try to isolate it at once, it goes on no matter what is on. I’ve updated every Windows և machine program. I am operating a modern malware protection system. Do you have any ideas?

A: No pun intended, but it looks like you should take a look at Event Viewer. You’ll find it by clicking the “Start” button and then scrolling to Windows Administrative Tools.

Event Viewer keeps track of many event logs under your computer cover, from applications accessing your USB ports to domain name server (DNS) errors over the Internet.

For most users, including me, the problem is that it is difficult to understand what Event Viewer reports. For example, at 8 o’clock this morning. 19: On the 40th, the viewer of my system login event reported that: “Application program-specific authorization settings do not grant Local Activation Permission for COM Server Application CLSID 2593F8B9-4EAF-457C-B68A-50F6B8EA6B54 և APPID {15C20B67-12E7-4BB6-92BB997BF -21-3313817969-2514332478-2302696435-1001) from the LocalHost address (using LRPC) in the application running inaccessible SID (inaccessible).

Yes

But since logs are time-stamped, if you check the exact time to hear those sounds, you can know what is going on. And if you can’t see the heads or tails you see, the technician probably can.
