Hi @Kin5413,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand your Compaq Presario 434 notebook is experiencing a driver or hardware-related issue, which is causing the blue screen when attempting to connect to WiFi. Here’s a step-by-step approach to help you resolve this:

1. Check Device Manager for Driver Issues

• Press Windows + X and select Device Manager.
• Look for Network adapters and expand the category.
• If there is a yellow triangle or exclamation mark next to your WiFi adapter, it indicates a problem.
• Right-click on the WiFi adapter and select Uninstall device. After uninstalling, reboot your computer.

2. Reinstall Network Driver

• Go to the HP website (HP/Compaq) and search for the correct drivers for your specific model.
• Download the correct WiFi driver and install it.
• If you cannot connect to the internet via WiFi, connect your laptop to a wired Ethernet connection or use another device to download the drivers and transfer them via USB.

3. Check BIOS Settings

• Restart your laptop and enter the BIOS/UEFI setup (usually by pressing Esc, F2, or Del during boot).
• Check if the wireless adapter is enabled in the BIOS settings. If it's disabled, enable it, save the changes, and exit.

4. Reset TCP/IP Stack

• Open Command Prompt as an administrator.
• Type the following commands, pressing Enter after each one: netsh winsock reset
  netsh int ip reset
  ipconfig /release
  ipconfig /renew
  ipconfig /flushdns
  
  
• Restart your computer and try reconnecting to WiFi.

5. Check for Windows Updates

• Go to Settings > Update & Security > Windows Update.
• Install any pending updates, especially if they include network-related fixes.

6. System Restore

• If the issue started recently, consider using System Restore to revert your system to a point when WiFi was working correctly.
• Go to Control Panel > Recovery > Open System Restore and follow the instructions to restore your system.

I hope this helps. 

Take care and have a good day.
