I have a small Dell laptop that has worked reliably for several years, but it recently began freezing after only a couple of minutes. The mouse cursor stops moving and the entire system appears unresponsive, so I can't open Task Manager or shut down normally. The only method I've used so far is unplugging the laptop and waiting for the battery to run out. I've used the same wired USB mouse for years, so I'm wondering whether the mouse, USB port, or a corrupted driver could be responsible. What troubleshooting steps should I try to identify the cause?

Avoid unplugging the laptop and waiting for the battery to drain, since repeated forced power losses can damage the Windows installation or corrupt open files. If the system is completely locked up, hold the physical power button for several seconds—often around four to ten—until it turns off. It’s still an emergency shutdown, but it’s safer and more practical than disconnecting power.
Since the mouse is connected by USB, uninstall the USB and mouse-related drivers from Device Manager, choosing the option to remove the driver files if it appears. Then restart and let Windows detect and reinstall them. It’s best to have an internet connection available so Windows can obtain replacement drivers.
Try starting Windows in Safe Mode and check Event Viewer for errors around the time of the freeze. If the laptop remains stable in Safe Mode, that points more toward a driver or startup program than a major hardware failure. On many Dell systems, the boot menu can be opened with F12, though the exact key may vary by model.
The mouse stopping may just be a symptom of the whole computer freezing, rather than the mouse causing it. Try disconnecting the mouse and using the touchpad, or test a different USB port and mouse. That can help determine whether the problem follows the peripheral or affects the entire system.
