Windows 10: Computer turns off without warning.

Recently, my computer has been shutting down as if the power was cut and then it reboots, without any BSOD or warning. I've attempted numerous fixes such as disabling fast startup, updating to the latest BIOS, and updating drivers, all while monitoring temperature levels. A few days ago, I thought the issue was resolved after reseating the memory, as there were no reboots for three days. However, the problem recurred with three consecutive shutdowns. The occurrences seem random. I'm seeking advice on what the issue might be and how to resolve it, as it's becoming quite frustrating.

NumLock Turns Letters Into Numbers on Desktop Computer

I had the same problem, it seems that it happens only with several keyboards.
Finally I solved it this way (sorry, but I've got Polish language set):

• Step 1 - Go to keyboard driver properties using Device Manager and select Update driver
  
• Step 2 - Select Browse my computer, then Allow me to choose from drivers list
  
• Step 3 - Uncheck "Show compatible hardware"
  

Now find something like "Standard keyboard device" on the drivers list, install it (click Yes in the compatibility warning window) and check if keyboard is still working.

If so - reboot Your computer and enjoy fixed keyboard without letters turning into numbers.

If not - revert driver back and try another one.

 

CAPS LOCK sound warning not working

Hi, here are some ideas: see if one works for you. Keep a list of what you try. If no success, please post back listing what you've tried. Thanks.

This is likely to be one of those where, as I don't know what you've already tried, I'll have spent time suggesting what you have tried. That's why I asked for a clear list of what you have tried. Do you see this when you toggle caps lock?

 

Cursor turning invisible without warning

Hi,

Thank you for posting your query in Microsoft Community. Appreciate your interest in using Windows 10.

I suggest you to check if the issue persists if the cursor is not changed and using the default mouse cursor for both gaming and accessing the computer. If the issue still persists, follow the steps below:

• Right click on Start icon and select Device Manager.
• Expand Mice and other pointing devices/touchpad.
• Right click on Mouse driver and click on uninstall.
• Restart the computer and check for status.
