How to Fix Keyboard Spamming Letters?

A properly working keyboard will just type in the letter when you press the corresponding key. However, there are instances where you may experience keyboard issues, one of the most common of which is keyboard spamming letters.

If your keyboard starts repeating letters when you press a key, it’s a serious issue with several possible causes. It’s important to first identify the cause of the problem so that you’ll know the next step to fix the issue.

#1 – Bad connection

A keyboard that’s not properly connected to the computer may cause the keyboard to spam letters. To ensure proper connection, make sure that the cable is securely connected to the computer’s port. And if connecting via USB, the keyboard should be directly connected to the computer and not through a USB hub.

Moreover, keyloggers and similar devices may cause the keys to repeat. If you own a PS/2 connected keyboard, you should shut down the computer first when disconnecting and reconnecting the keyboard.

#2 – Liquid or food particles in the keyboard

Eating or drinking near your computer can cause accidental spillage on your keyboard. This in turn can cause the keys to stick and spam or repeat letters. You may try using canned air to blow out any food or liquid residue then check if that solves the problem.

If the issue persists, you may have to pull off the keys and clean them underneath using a clean cloth with rubbing alcohol.

#3 – Keyboard wear and tear

Computer keyboards can wear down over time, causing some keys to start sticking during a keystroke. More often, the keys won’t release back immediately as they normally should, causing the keys to repeat. In some cases, the keys may go back to their position as they should but it’s the circuit board underneath that sticks. When any of these things happen, it’s best to replace the keyboard.

#4 – Software glitch

Although this is not a very common cause of spamming letters, it can happen to you anytime. A software program that’s receiving and interpreting the inputs from your keyboard may experience some glitch and can cause the keys to repeat.

One easy solution for this problem is to restart your computer. However if the issue continues after restarting your computer, check if there are latest updates on the software problem and make sure to install those updates.

#5 – Virus or Malware infection

If your computer is infected with a virus or malware that interferes with your computer software’s ability to properly interpret keyboard strokes, it can cause spamming letters.

To solve keyboard spamming letters caused by viruses or malware, update the antivirus program on your computer, or install one and scan your computer, if you have not already.
