USB Mouse Not Working? Fix It in 10 Steps

If your USB mouse has stopped working, the fix is usually a simple driver reset, a different port, or a quick reboot—not a new mouse. Follow the steps below in order, and you’ll likely be back to clicking within minutes.

Why a USB Mouse Stops Working

A USB mouse can fail for several reasons, and most are not hardware failures. The most common causes are:

• Driver issues – Windows or macOS may have installed an incompatible or corrupted driver after an update.
• Power management – The USB port may be set to “sleepâ€� to save power, cutting off the mouse.
• Port problems – A dead USB port, loose connection, or a port that doesn’t supply enough power.
• Software conflicts – Another program (like a gaming utility) can interfere with mouse input.
• Physical damage – A frayed cable, broken connector, or worn-out switch.

Understanding the cause helps you pick the right fix. But even if you don’t know the cause, the steps below will cover nearly every scenario.

Step 1: Check the Basics (Cable, Port, Power)

Before diving into software, eliminate the obvious:

1. Unplug the mouse and plug it into a different USB port. Prefer a port directly on the computer (not a hub).
2. If it’s a wired mouse, inspect the cable for cuts or kinks. Bend it gently near the connector—if the mouse flickers, the cable is damaged.
3. For wireless mice, check the batteries. Replace them even if they seem fine; low batteries cause erratic behavior.
4. If using a USB receiver, try plugging it into another port, and make sure the receiver is fully seated.

If the mouse works in a different port, the original port is dead or misconfigured. If it still doesn’t work, move to the next step.

Step 2: Restart Your Computer

A simple reboot fixes a surprising number of USB issues. It clears temporary glitches in the USB controller and reloads drivers. Save your work, then restart. When the computer comes back, test the mouse. If it works, you’re done—the problem was a transient software issue.

If the mouse doesn’t work even after a restart, try a “hard reset� (for desktops, unplug the power cord for 30 seconds; for laptops, hold the power button for 15 seconds). This drains residual power that can keep USB ports in a bad state.

Step 3: Update or Reinstall the Mouse Driver

Driver corruption is the #1 software cause. Here’s how to fix it on Windows:

1. Right-click the Start button and select Device Manager.
2. Expand Mice and other pointing devices.
3. Right-click your mouse (usually “HID-compliant mouse�) and choose Uninstall device.
4. Check the box “Delete the driver software for this device� if offered, then click Uninstall.
5. Restart your computer. Windows will automatically reinstall the correct driver.

On macOS, drivers are built-in, but you can reset the USB controller by shutting down, unplugging everything, waiting 30 seconds, then plugging the mouse back in and booting.

If the driver reinstall doesn’t work, check the manufacturer’s website for a specific driver, but for most standard mice, Windows’ generic driver is sufficient.

Step 4: Disable USB Power Saving

Windows can suspend USB ports to save power, which sometimes prevents the mouse from waking up. To disable this:

1. Open Device Manager again.
2. Expand Universal Serial Bus controllers.
3. Right-click each entry like “USB Root Hub� and select Properties.
4. Go to the Power Management tab.
5. Uncheck “Allow the computer to turn off this device to save power.�
6. Click OK and repeat for all USB Root Hubs.

This is a common fix for mice that freeze after the computer has been idle.

Step 5: Check for Hardware Conflicts

Sometimes another USB device (like a printer or external drive) conflicts with the mouse. Unplug all other USB devices except the mouse and see if it works. If it does, plug the others back one by one to find the culprit.

Also, check if the mouse works in Safe Mode (Windows) or Safe Boot (macOS). If it works there, a third-party program is interfering. Boot normally and uninstall recently installed software, especially anything that customizes mouse behavior (e.g., gaming mice software, utility apps).

Step 6: Try the Mouse on Another Computer

This is the definitive test. Plug the mouse into a different computer. If it works there, the mouse is fine and the problem is with your original system. If it doesn’t work, the mouse itself is likely dead.

For wireless mice, try pairing again (usually a button on the receiver and one on the mouse). Consult the mouse’s manual for the exact pairing procedure.

Step 7: Use a Different Mouse (or the Keyboard)

If you have a spare mouse, plug it in. If the spare works, your original mouse is probably faulty. If the spare doesn’t work either, the issue is with your computer’s USB system or OS.

While troubleshooting, you can still navigate using keyboard shortcuts: Tab moves between items, Enter selects, and Alt+Tab switches windows. On macOS, use Cmd+Tab and Ctrl+F2 to access menus.

Frequently Asked Questions

Why does my mouse work in the BIOS but not in Windows?

If the mouse works during boot (BIOS) but not in Windows, the problem is a driver or software issue. Follow the driver reinstall steps (Step 3) and disable USB power saving (Step 4). Also, boot into Safe Mode to see if a third-party driver is the issue.

My wireless mouse is paired but won’t move. What else can I try?

First, replace the batteries. Then, remove the USB receiver and plug it into a port directly on the computer. Try pairing again. If it still doesn’t work, the mouse or receiver may be defective. Test with another receiver if possible.

Can a USB hub cause mouse problems?

Yes. USB hubs, especially unpowered ones, may not supply enough power or can introduce interference. Always connect the mouse directly to the computer’s USB port. If you must use a hub, use a powered one.

How do I fix a mouse that freezes randomly?

Random freezes are often caused by power management or driver issues. Disable USB power saving (Step 4), update the chipset drivers, and check for overheating. Also, try a different USB port—some ports share controllers and can be overloaded.

Is it worth repairing a dead USB mouse?

Generally, no. Basic wired mice are inexpensive, and repair costs (if you can find a shop) usually exceed the price of a new one. However, if it’s a high-end gaming mouse, check the warranty first—many have 2-3 year coverage.

Why does my mouse work on a Mac but not on Windows?

This usually indicates a driver issue on the Windows side. Some mice (especially older ones) need specific drivers for Windows. Check the manufacturer’s website for a Windows driver. Also, try a different USB port and ensure the mouse is properly recognized in Device Manager.
