Fix USB Mouse and Keyboard Stop Working Issue in Windows 7

Camilla Mo, in Common error Tags: Windows 7
It can be frustrating if neither mouse nor keyboard doesn’t work at all. If your USB mouse and keyboard stop working in Windows 7 even in login screen, don’t be panic. Use the solutions in this post and they should work again.

Before you try further solutions, ensure the mouse and the keyboard are working fine. If possible, try to use them on another computer. If they are working fine on another computer, try the solutions below. If not, you might need to replace them with the new ones.

Solution 1: Unplug the keyboard then plug it back

This would work if the issue is caused by missing drivers. After you unplug and replug the keyboard, Windows may install the USB driver automatically.

Solution 2: Disconnect the power cable for a while

First, shut down your computer. Then disconnect the power cable (If you are using a laptop computer, you can also remove the battery.). Then hold the power button down for about 10 seconds. After that, restart your computer and see if the issue resolves. This solution may work like a charm for you.

Solution 3: Enable Legacy USB Support in BIOS

The issue would occur if Legacy USB Support is disabled in BIOS. So enter BIOS (basic input/output system) and make sure the Legacy USB Support is enabled. The key command to enter BIOS and get to the Legacy USB port depends on the PC brand that you are using. Refer steps below to get to the Legacy USB port.

1. Enter BIOS (See How to Enter BIOS in Windows 7). 

2. In BIOS, use the specific key to navigate to Advanced (You can see the meaning of the key command at the bottom of the screen.).


3. Find Legacy USB Support or similar USB option. If it is Disabled, enable it. Exit after saving the changes. 



Note if you don’t find Legacy USB Support in BIOS, it is possible that the BIOS does not provide this option and this solution does not work for you. If you are still not sure how to do this, contact the PC manufacturer for further assistance. 

Solution 4: Disable Third Party services

The issue can be caused by some of the Third Party services. So disabling the Third Party services may fix the issue. Since you can’t use the mouse and keyboard in Normal Mode. Enter Safe Mode (See How to Enter Safe Mode in Windows 7) then follow steps below.

1. Press Win+R (Windows logo key and R key) at the same time. A Run dialog box will open.

2. Type msconfig in the run box and click OK button.



3. Go to Services tab. Check the box next to Hide all Microsoft services then click Disable all.



4. Click OK button.

5. When  you are prompted, click Restart. Then your computer will restart.


If the issue resolves after the computer starts, you can try disabling the third party services one by one to determine which service is causing the issue. 

Solution 5: Disable driver signature enforcement

Follow steps below:

1. Press F8 key in 1 second intervals once you power on the computer. 

2. When the Advanced Boot Options screen displays, use the arrow key to select Disable Driver Signature Enforcement.



3. Press Enter key then Windows will restart.

Solution 6: Update USB driver in Safe Mode


If the USB driver is missing or corrupted, this issue can occur. To fix the issue, you can update the USB driver in Safe Mode. You’ll need to search for new drivers online, so enter Safe Mode with Networking.

Before updating drivers, delete the driver first. Follow steps below:

1. Press Win+R (Windows logo key and R key) at the same time. A Run dialog box will open.

2. Type devmgmt.msc in the run box and click OK button.



3. Expand category “Universal Serial Bus controllers” and locate device USB 3.0 eXtensible Host Controller and something like that. If you can’t find the usb device under this category, expand category Other devices. You may find the device with a yellow mark there.



4. Press Del (Delete on some keyboards).

5. Check the box next to Delete the driver software for this device.


6. Click OK button to confirm the uninstall.

After uninstalling the drivers, update the drivers.

You can go to the PC manufacturer’s website to download the latest USB driver for your computer. To download the correct driver, you need to know the PC model and the operating system version that you are using (see How to Get Operating System Version).

If you have difficulty downloading the drivers manually, you can use Driver Easy to help update the drivers. Driver Easy can scan your computer to detect all problem drivers. It has Free version and PRO version. Both versions can be used to download the drivers automatically. But with the PRO version, you can enjoy 10X faster download speed and full features. You can update all drivers with just 2 mouse clicks.

What’s more, you can enjoy free expert tech support guarantee. You can contact us for further assistance regarding any driver issues if you need. You can enjoy 30-day money back guarantee. You can ask for a full refund for any reason. Click here for more purchase details.


If the mouse and keyboard don’t work in Safe Mode either, you might need to take the computer to the repair store to have a further check.

Hope the solutions here helps you fix the mouse and keyboard not working issue in Windows 7.
