How to Fix Driver Errors on Your PC

When driver errors strike

Driver errors are among the most frustrating problems a PC user can face. One moment everything is working fine; the next, your screen goes black, your audio cuts out, or Windows crashes with a dreaded blue screen. The good news is that most driver errors can be diagnosed and fixed without professional help — if you know where to look.

Common signs of a driver error

Driver problems can show up in a variety of ways:

Blue Screen of Death (BSOD) with error codes like DRIVER_IRQL_NOT_LESS_OR_EQUAL or PAGE_FAULT_IN_NONPAGED_AREA
Yellow exclamation mark (!) in Device Manager next to a device
Hardware that worked yesterday suddenly stops functioning
Audio, video, or network drops randomly
Device not recognised by Windows
Frequent system crashes or restarts

Step 1: Identify the problematic driver

Before you can fix a driver error, you need to find the source. Here's how:

Use Device Manager

Right-click the Start button and open Device Manager.
Look for any device with a yellow warning triangle or red X.
Right-click that device and select Properties.
Read the error code in the Device status box — note it down.

Check Event Viewer

Press Windows + X, select Event Viewer, then navigate to Windows Logs > System. Look for critical errors or warnings flagged in red or yellow — these often point directly to a driver or hardware failure.

Step 2: Update the faulty driver

The most common fix for driver errors is simply installing the latest driver version. Right-click the problematic device in Device Manager and choose Update driver. Then select Search automatically. If Windows doesn't find a newer version, visit the manufacturer's website and download the latest driver manually.

Step 3: Roll back to a previous driver

If the error started after a recent driver update, rolling back to the previous version often resolves the issue instantly. To do this, open Device Manager, right-click the device, choose Properties, go to the Driver tab, and click Roll Back Driver. Confirm the rollback and restart your PC.

Step 4: Uninstall and reinstall the driver

A corrupted or incomplete driver installation can cause persistent errors. The cleanest fix is to fully remove the driver and reinstall it from scratch. In Device Manager, right-click the device and select Uninstall device. Check the box that says Delete the driver software for this device, then restart your PC. Windows will attempt to reinstall the driver automatically. If it doesn't, download the driver from the manufacturer's site and install it manually.

Step 5: Run the Windows built-in repair tools

Windows includes built-in repair tools that can automatically detect and fix common driver-related problems. Open Settings, then go to System and look for the built-in repair tools section. Run the repair tool most relevant to your issue — for example, Hardware and Devices, Printer, Bluetooth, or Internet Connections.

Step 6: Check for Windows updates

Microsoft frequently releases patches that fix known driver compatibility issues. Open Settings > Windows Update and run a full check to ensure your system is current.

When to suspect hardware, not the driver

If you've tried every driver fix and the problem persists, the hardware component itself may be failing. Signs of physical hardware failure include: the device is not detected at all even after driver reinstall, errors appear in hardware diagnostics tools, or the device produces unusual noises (for mechanical drives). In these cases, professional repair or hardware replacement may be necessary.

Final thoughts

Driver errors can feel overwhelming, but a systematic approach almost always leads to a solution. Start by identifying which device is causing the problem, then work through updating, rolling back, and reinstalling before assuming the worst. With patience and the right steps, you can get your PC back to full health.
