After rolling back, restart your computer and check if the exclamation mark is gone. If the rollback solves the issue, it’s best to avoid updating that particular driver until the manufacturer releases a more stable version.

Step 3: Hardware Conflict – Resolving Resource Clashes

Hardware conflicts can be a bit trickier, but here's how to identify and resolve them:

• Check Device Manager for Errors: Look for any error messages associated with the conflicting devices. They might share the same resources (IRQ, I/O ports, etc.).
• Manual Resource Allocation (Advanced): This is usually handled automatically, but if you're comfortable, you can try manually allocating resources. Right-click on the conflicting device, go to "Properties," and then the "Resources" tab. You might see a resource conflict listed. You can try to change the resources assigned to the device, but be careful as incorrect changes can cause further problems. You may need to disable one of the conflicting devices to allow the other to function. This approach should be used with caution, as it requires a good understanding of hardware configuration. Before making any changes, it is essential to understand the implications of adjusting these settings. Incorrect resource allocation can prevent devices from working properly or lead to other system issues.
• Update BIOS: A BIOS update can sometimes improve resource allocation. Check your motherboard manufacturer's website for BIOS updates and instructions.

Step 4: Reinstall the Device – A Clean Start

If the other steps haven't worked, reinstalling the device might be the solution:
