How to Find Missing Drivers for Your Old HP 15-bs091ms Laptop

Select Language:

If you’re having trouble with your 15-bs091ms laptop after reinstalling Windows 10 64-bit and are seeing errors like “Base System Device Driver Not Installed,” along with issues with PCI Data Acquisition and Processing Controller, and PCI Memory Controller drivers, here’s a simple way to fix it.

First, don’t worry — your laptop is still useful for basic tasks like document creation. The problem is that Windows doesn’t have the right drivers installed for some hardware components. Here’s what you can do:

1. Identify Your Laptop Model Precisely
   Make sure you have the correct model number (15-bs091ms). Sometimes, specific driver versions depend on the exact model.

2. Visit the Official Manufacturer’s Website
   Go to the site where you bought your laptop or the manufacturer’s support page. Search for your specific model to find the latest drivers tailored for it.

3. Download and Install Drivers
   Look for chipset drivers, as these are often responsible for many of those ‘unknown device’ errors. Download the drivers labeled as “Chipset” or “Motherboard” drivers. Installing these usually resolves missing device issues.

4. Use Driver Update Tools
   If you’re unsure which drivers are correct, you can try tools like Driver Booster or the official driver update utility from the manufacturer. These tools scan your system and suggest the right drivers automatically.

5. Update via Windows Update
   Sometimes, running Windows Update can also find and install necessary drivers. Go to Settings > Update & Security > Windows Update, and click “Check for updates.”

6. Install Drivers in the Correct Order
   Start with chipset drivers, then move to other hardware drivers. After installing each driver, restart your laptop to see if the issues are resolved.

7. Check Device Manager
   Open Device Manager and see if the errors are gone after the driver installs. If you still see the devices marked with a yellow warning sign, right-click on them and select “Update Driver,” then choose “Search automatically for updated driver software.”

Following these steps usually fixes driver problems on older laptops. If you still struggle, consider contacting customer support for the laptop or visiting a computer technician for help. This method saves you time and gets your device back to working smoothly for everyday tasks.
