HELP! installed new drivers from Hp and now blue screen and system crashes occurr!

I am so frustrated. I installed new updates from the HP site, and also Windows Update, now my Network Adapters are causing system crash often. I get the blue screen with this message:

error code e100b325.sys

I HAVE TRIED TO PUT BACK THE OLD DRIVERS AND IT FAILED. HP HAS NO news or has not created new drivers to fix this issue.

when it boots, it gives me a prompt saying the following. But the instructions cannot be followed as instructed because they do not work on Windows Vista 32 bit. Maybe for XP.

Any help on this matter would be greatly appreciated!

Troubleshooting

To try to solve this problem, follow these steps. One step might solve the problem, but if it doesn't, then go on to the next step.

1. Check for updated networking drivers
   Some networking hardware drivers might be listed as optional hardware updates in Windows Update. To check for and install optional hardware updates, follow these steps:
   
   • Open Windows Update:
     
     
     Windows Update
   • Click the Check for Updates link in the left pane, and then click View available updates.

     • If you see the You receive updates: Managed by your system administrator message you can try clicking the link to Check online for updates from Microsoft Update or Check online for updates from Windows Update but you might need to contact your system administrator to obtain the desired updates.
     • If you don't see the message above and no updates are available in Windows Update after clicking the Check for Updates link in the left pane, then the available updates have already been installed.
   • Select driver updates for your device and any other updates you want to install.
     Note
     We recommend that you install all Important and Recommended updates. These updates improve your computer's security and stability.
   • Click Install.
     
     If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
   
   
2. Run Diagnose and Repair
   The Diagnose and Repair feature in this version of Windows can help identify and fix network connection problems. To run Diagnose and Repair:
   
   • Click the Start button
     
     , and then, in the Search box, type network.
   • In the list of search results, double-click Network and Sharing Center.

   • Wait for Windows Network Diagnostics to identify the problem.
   • If a problem is found, take the recommended action.
   • Rerun Diagnose and Repair to confirm that the problem has been resolved.
3. Collect information about your computer and search Windows Vista Communities for a solution
   
   To continue troubleshooting this problem, you will need to collect more information about your computer and use it to find more information online.
   • Find the device name and driver name for your Ethernet network hardware and print out your system information
     
     
     • Click the Start button
       
       , and then, in the Search box, type msinfo32.exe.
     • In the list of search results, click msinfo32.exe.
     • In the left pane, double-click Components, double-click Network, and then click Adapter. Search for any adapter that references "Ethernet," and then, for each one found, write down its name, adapter type, product type, and driver (typically, the driver will be a file with a file name extension of .sys and a name such as Portcls.sys).
     • In the left pane, click System Summary.
     • Click File, click Print, select a printer, and then click Print.
       
       
       
       If you do not have a printer and you want to copy the system information, click Edit, click Select All, press CTRL+C, open a program in which to paste the information (such as WordPad), and then press CTRL+V.
   • Use Event Viewer to find specific information about this problem
     Event Viewer is an advanced tool that displays detailed information about significant events on your computer. It can be helpful when troubleshooting problems and errors with Windows and other programs.
     
     • Click the Start button
       
       , and then, in the Search box, type Event Viewer.
     • In the list of search results, double-click Event Viewer.

     • In the Actions pane on the right side of the window, click Find.
     • In the Find dialog box, type bluescreen, and then click Find Next. When a blue screen event is located, close the Find dialog box.
       Note
       If no blue screen events are found, this is most likely because a problem report was not submitted to Microsoft. The blue screen event and its fault bucket are created only after the problem report is submitted, so if the blue screen error happens again, be sure to choose the option for sending in the report.
     • In the Actions pane, click Event Properties.
     • Click the General tab, and then locate and write down the Fault bucket. An example fault bucket is "0xD1_W_portcls!CPortWavePci::Notify+12."
   • Use the Windows Vista Communities to troubleshoot this problem
     
     
     • Go online to the Discussions in Windows Vista Hardware and Devices.
     • In the Search For box, type the fault bucket name, and then click Go. This will give you a list of the posts that include this fault bucket. From the results, you might be able to determine if anyone else is also experiencing this problem. If you don't get any results, try searching for the driver name or the sound card name. If you get too many results, you can add other keywords to your search, such as your system information.
     • If you don't find a solution to your problem in the search results, you can post your own question by clicking New. To post questions, you need a Windows Live ID. We recommend that you provide as much system information about your computer as possible with your question.
       
       
       Go online to get a Windows Live ID
       
       What is a Windows Live ID?
       If you already have an MSN Hotmail, MSN Messenger, or Microsoft Passport account, you've already got a Windows Live account. You can go online to sign in now with your current account information to start using Windows Live. If you don't have a Windows Live ID, you can go online to Get your Windows Live ID to sign up.
       
     • If you don't find a solution to your problem in the Windows Vista Communities, you can go online to search the Internet for the fault bucket name or the driver name. If you find troubleshooting steps for your problem, we do not recommend following them unless they are for your specific brand and model of computer.
4. Disable Auto-Tuning
   Receive Window Auto-Tuning is a feature in this version of Windows that improves networking performance when you are using newer networking hardware, but the feature might cause problems with older networking hardware. Disabling Auto-Tuning might solve your problem.

   • When the process has finished, restart your computer. If this procedure does not solve the problem, you can turn Auto-Tuning back on by repeating steps a and b of this procedure, typing netsh int tcp set global autotuninglevel=normal, and then pressing Enter.
5. Disable your Ethernet network adapter
   If you are unable to troubleshoot this problem, or if the error continues, you can disable your Ethernet network adapter. Once the adapter is disabled, you might not have networking capabilities on your computer, but the error should stop occurring.

   To disable your Ethernet network adapter, follow these steps:
   
   • Click to open Device Manager.
     
     If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
