Keyboard buttons randomly stop working

Aug 15, 2018
My keyboard buttons randomly stop working especially while playing games.Also when i login into my laptop on password screen some alpha numeric button is pressed randomly but this happens only at the first attempt.Could this be a hard drive issue or a malware issue?? I haven't yet tried a external usb keyboard.The problem is not restricted to only few keys, it happens to any alphabetical key.
Try an external keyboard first. If it doesn't happen with that, then try uninstalling the attached keyboards driver, restart the computer (without reinstalling it) and it should reinstall on its own. Should it still do it after that, It may well be the keyboard itself then.

If you are worried it could be something 'on' the computer, try starting in "Safe Mode" and see if happens there. If it still happens, then it is more likely the keyboard.

How to enter "Safe Mode" when booting the computer.

In Windows 8 and 10...

As your computer restarts, press F8 (possibly a few times) to enter "Safe Mode"

a. Press the "F4" key to Enable "Safe Mode".
(The computer will then start in "Safe Mode" with a minimal set of drivers and services.)

b. Press the "F5" key to Enable "Safe Mode" with Networking.
( Once "Safe Mode" with Networking starts, Windows is in Safe Mode, with additional network and services for accessing the Internet and other computers on your network.)

c. Press the "F6" key to Enable "Safe Mode" with Command Prompt.
(In "Safe Mode" with "Command Prompt" starts Windows in Safe Mode, with a Command Prompt window instead of the Windows interface. This option is mostly only used by IT professionals.)

Now sign in to the computer with your account name and password. (If you have one set.) When you are finished troubleshooting, you can exit "Safe Mode" restarting your computer.

In Windows 7/Vista/XP...

1. Immediately after turning on the computer, or restarting it (usually after you hear your computer beep), tap the F8 key, repeatedly, in 1 second intervals.

2. The computer will then display hardware information and run a memory test.

3. Next the "Advanced Boot Options" menu will appear.

4. In the "Advanced Boot Options" menu use the arrow keys to select "Safe Mode" or "Safe Mode with Networking" and press ENTER.
