If some of your keyboard keys are not working, it may be due to a hardware issue or it could be a software issue. Here are some troubleshooting tips to help you figure out the problem and fix it.

First, check to see if the keys that are not working are sticky or dirty. If they are, you can try cleaning them with a mild soap and water solution. If that doesn't work, you may need to replace the keys.

If the keys are not sticky or dirty, the next step is to check your keyboard driver. To do this, go to the Device Manager in Windows. Find the keyboard device and double-click on it.

Click on the Driver tab and click on Update Driver. If there is an update available, follow the prompts to install it.

If updating the driver does not fix the problem, the next step is to try a different keyboard. If you have another keyboard that you can use, plug it in and see if the keys that are not working work on that keyboard.

If the keys still don't work, the problem is most likely a hardware issue. The best way to fix a hardware issue is to take the keyboard to a computer repair shop. They will be able to diagnose the problem and replace any damaged parts.
