Hi @Mica1234 

Welcome to the HP Support Community! We're here to help you get back up and running.

I’m sorry you’re dealing with this—it’s stressful when the system stops working just because of a driver update, especially when warnings about bad drivers keep appearing. 

Let’s walk through a careful way to stabilize your PC with the NVIDIA Quadro M620.

1. Remove the faulty driver completely

Start Windows in Safe Mode (press Shift while selecting Restart > Troubleshoot > Advanced Options > Startup Settings > Restart > choose 4 or F4).

In Safe Mode, uninstall the NVIDIA driver:

Press Windows + X, open Device Manager.

Expand Display adapters.

Right-click NVIDIA Quadro M620 and select Uninstall device.

Check Delete the driver software for this device, then confirm.

2. Install a stable NVIDIA driver

Instead of updating through Windows Update or automatic tools, install a tested version directly:

Download the Quadro M620 driver from NVIDIA’s site:
NVIDIA Quadro M620 Drivers

When installing, choose Custom (Advanced) > Perform a clean installation.

3. Block Windows from automatically reinstalling the faulty driver

Press Windows + R, type gpedit.msc (if available in your edition).

Go to Computer Configuration > Administrative Templates > System > Device Installation > Device Installation Restrictions.

Enable the setting: Prevent installation of devices that match these device IDs.

Alternatively, use Microsoft’s “Show or Hide Updates” troubleshooter tool:
Hide Windows Updates Tool

4. Update BIOS and chipset drivers

Sometimes display driver crashes are linked to outdated system firmware.

5. Run hardware diagnostics

To rule out a hardware fault with the GPU:

Restart the PC and press Esc repeatedly, then F2 to enter HP PC Hardware Diagnostics UEFI.

Run the Graphics test.
