Win 7 x64 - Need to repair a single driver, but can't use System Restore

Question

Basic Info - an HP/Compaq Elite 8200 Convewrtible Minitower with 2 extra SATA drives & a Creative SoundBlaster card installed.
Background:  My system had begun going into Blue Screen (BS hereafter) every couple of days with a message that the BIOS was not "fully ACPI compliant."  I contaced HP and was able to obtain & install the needed BIOS upgrade.  Following this, I decided to do some housekeeping & checked for out-of-date drivers.  I installed these one at a time, as I had a previous bad experience with updating too many drivers, particularly Intel chipset drivers, at a single time.  When I finished the last update, which involved two drivers labeled IntStrA and IntStrB, if I recall correctly (I'm posting this from my PC at work, so I may have the names off by a character or so) my system began going BS after ~10 minutes or so.  Nearly every BS referenced the MicroSoft system driver wdf01000.sys.
It is my belief that either wdf01000.sys became corrupted, or the last 2 updates were having a negative impact on the M S driver.  Unfortunately, if I try to use System Restore to roll back the suspect updates, the system will BS ~1-2 minutes after the m essage "Restore is initializing" appears.
The only solution I can get from the HP Tech is to back up my data and then use the "Erase, Reformat & Reinstall" function from the Recovery Disks.  Unfortunately, with a system that goes B S every 10 minutes, it is impossible to perform a reliable back-up for all 3 disks, while the Recovery Disk is only willing to back up my drive F:\, not my primary OS Drive, C:\ or my other drive, G:\ (the HP Recovery partition is drive D:\).
My questions are:
1.  If the problem is a corrupted WDF01000.sys is it possible to obtain a reliable copy of & replace it?  (The HP tech warned about the danger of obtaining a copy of a MicroSoft sysem file from the internet - a danger of which I was fully aware - but, isn't there at least one system in HP's possession running Windows 7 x64 professional?  I should think a file supplied from HP would be sufficiently safe.  However, when I raise the possibility with the tech, there is no response.)
2.  If the problem stems from the last 2 Intel driver updates, is there a way to get a functional OS loaded from DVD that would peremit System Restore to run?  My last system had Win 7 installed from MS media and, as I recall, once loaded, the use of System Restore was one of the repair options.  The HP Recolvery disks only offer 2 choices - back-up (which would only cover drive F:\, with <10% of my 4+ years worth of data) or "Erase, Reformat & Reinstall."  Following this course would put at risk ~90% of my data, not to mention the grief of reinstalling a great deal of software.
3.  The HP tech tells me that, since Recovery is only willing to back up drive F:\, this is where the Recovered OS would be installed.  This would give me the independently loaded OS I sought in question 2.   However, I greatly fear that drive where recovery operated would be my primary OS drive, C:\.  If this were the case, the result would be disastrous!  I do have back-up via Carbonite, but I don't think this has been operating properly since the ACPI-related BSs began.
So -- any suggestions?  Anything that gets me out of this problem without loss of data will be most sincerely appreciated!

Hello TomF,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that after running some updates your system is getting BSOD errors associated with the Windows file wdf01000.sys. Now I cannot claim to be able to get you a copy of that file. I am not sure just replacing it would resolve your issue anyways. I can do this for you I can tell you that first the HP Compaq 8200 Elite Convertible Minitower PC is a commercial product. You can do this at you may get more assistance by posting this on the commercial forums at  Business PCs - Compaq, Elite, Pro.
Additionally, I would suggest you start your computer in Safe Mode and using an elevated command prompt run the command "SFC /SCANNOW". You can do this by right-clicking on the Command Prompt link and choosing Run as adminstator. Also, you can use chkdsk to run another repair on your files to see if they can be repaired.
The SFC /SCANNOW command will run the System File Checker to see if it can repair any corrupted system files where the chkdsk will do the same, but for ALL the files on your computer.
I am also providing you with resources on both below:
Use the System File Checker tool to repair missing or corrupted system files
Run Check Disk from a Command Line to Check for and fix Disk Errors
I hope this helps. Thank you for posting on the HP Forums. Have a great day!
