Have a new Vista Premium system. It's an HP Pavilion a6250z. My monitor is an HP w2007. Display Adapter is NVIDIA GeForce 8500 GT with 512MB. 3GB RAM. Athlon 64 X2 Dual Core 4600+ 2.4 GHz.

Everything seems to be running great except that I cannot get the drivers for the monitor to install. No matter what I try, I get either an error has occured or Access Denied when I attempt to run the installation program.

When I look at my display properties it shows the correct monitor, however it shows there being no driver. In Device Manager the Monitor shows under Other Devices. My monitor seems to work ok...but there is a hugely noticiable quality difference between the display when connected to the new Vista machine and the older XP machine.

I've been through forums all over the net and tried everything I've found.

I've tried:

- Right-Click Run as Admin
- Creating/Using the Super Administrator Account
- Uninstalling Monitor and Detecting Hardware Changes
- Updating Driver from Display Properties
- Updating Driver from Device Manager
- Uninstalling Monitor, Rebooting in Safe-Mode, Logging in as Super Admin
- I've installed directly from CD
- Copied files to desktop and ran
- Downloaded new drivers directly from HP and ran from desktop
- I've even tried running the driver install in XP SP2 compat mode...just to be sure

I've done everything I can think of. Anyone have any suggestions? I really hate to have to uninstall everything and load an old copy of XP instead.

Thanks for all your help!

I presume that you've got the 32 bit version of Vista and not the 64 bit version? If so....

Have you downloaded the drivers from this link? http://h10025.www1.hp.com/ewfrf/wc/softwar...289&lang=en

Have you updated your nVidia display drivers also? Here's a link to them: http://www.nvidia.com/object/winvista_x86_163.75.html

If you have the 64 bit version, then it appears that HP doesn't have a 64 bit driver for your monitor (here's the 64 bit nVidia drivers: http://www.nvidia.com/object/winvista_x64_163.75.html ) - so you won't be able to install it that way. Maybe you can find out who actually built the monitor for HP to see if there are 64 bit drivers at their website.

The following link is the last page of a 32 page topic about your monitor - it seems to indicate that there are some issues with the monitor depending upon which LCD screen you've got: http://www.hardforum.com/showthread.php?t=...531&page=32

I have had the same EXACT problem with the w2007 monitor and my HP Pavilion m8100n. I tried all of the same steps you have with absolutely no luck. I finally got somebody at HP to adequately help me out via IM (about 30 minutes ago). I could have sworn I tried all of these steps previously, but I guess not since it worked this time.

These are the steps s/he gave me:
  • Disable UAC by following the below click trail
    • Control Panel >> User Account and Family Safety >> User Accounts >> Turn User Account Control on or off >> Uncheck the UAC box and click OK (NOTE: You will need to restart your computer for this to take effect)
  • Install the HP My Display Software. The HP My Display Software has the monitor drivers built into it.
    • If My Display Software doesn't bring the driver back, follow Step 2.
  • Click Start -> All Programs -> HP My Display -> Display Diagnostic Utility.
    • In the Display Diagnostic Utility click on “Clean Registry”. A Clean Reg Window would open, Click on “Yes”
    • On restart you will have “Other Devices” with “Generic Monitor” List under that same.
    • Continue the process of "Clean Registry" until you get "Other Devices" with "Generic Monitor" listed under that same.
  • Install Monitor Drives by doing "Drive Update Software" and directing it to the system32 folder or install monitor drivers from the CD. Or you can try installing the driver available in HP web site.
    • If vista finds the drivers in the system32 folder on its own, it would install the drivers automatically.
These steps worked for me! Hope it works for you. Let me know how it turns out. :huh:
