I have found a thread that takes you through uninstalling the old ATI driver to install the new one here

http://www.rage3d.com/forum/ubbhtml/...13-004006.html


It suggests


1). Uninstall your current ATI display driver. Do this by going into your control panel and running add/remove programs. ATI Display Driver should be one of the first few on your list. Choose yes when it asks if you would like to uninstall. Choose no when it asks to reboot.


Done


2). Remove all leftover .inf files. Windows will use these to reinstall drivers (or at least try) without giving you an option for a clean install. To do this, you'll want to do a find all files/search, which can be accessed via the start menu. Windows ME has it labelled as search, and I believe Windows 9x has it labelled as find. In the search window, you'll want to enter ati*.inf as the target file. Don't bother making it search your whole hard disk, instead, under the look in field, type in C:\\Windows\\Inf, and make sure look in sub-folders is checked. Now your set, click find/search. Delete all files which it reports (make sure the location is c:\\windows\\inf or c:\\windows\\inf\\other, do not delete ati*.inf files in other directories, just in case you chose to search your entire hard drive). Once you've completed the .inf flush, you're now ready to move on.

========================================


Done, this works for WinXP as well:


3). Reboot your computer. Windows will load with a default VGA adapter driver, which the ATI uninstall conveniently installs for you. Little do we know, ATI forgot to take out all the registry settings, ack! Here's what you need to do...

========================================


Mmmh, here is where things start to go wrong... XP autodetects the hardware and installs the drivers... cannot stop it or prompt it to install the correct ones!


4). Run regedit. To do this, hit Start, click Run, and type regedit in the field and press Enter or hit OK. The windows registry entry will pop up. There are two sections you'll need to delete garbage from, the first one being the key HKEY_LOCAL_MACHINE\\SOFTWARE. Click the plus next to software and in the directory tree below it you will see a key labelled ATI Technologies, simply highlight this key and hit the delete key on your keyboard. Click yes to confirm removal when Windows prompts you. That will fix all previous tweaks you may have done, so you can ensure a fresh driver install at default settings. Now, on to the next key(s) you'll want to delete. WARNING! The following keys which I recommend you delete automatically assume you are using only one display adapter(video card) in your system. If you are using more than one, I will assume you are literate enough to know which keys can safely be deleted without mucking up your secondary adapter. Go to the registry key HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\Cla ss\\DISPLAY, click the plus next to DISPLAY and you will see at least one sub key, normally labelled 0000. If your registry is dirty, you will likely see multiple keys, such as 0001, 0002, 0003, and so on. If you have only one video card in your system, it is now safe to delete every sub key of DISPLAY, including 0000. To do this highlight each key respectively and hit the delete key on your keyboard, click yes when Windows asks if you wish to remove the entry. Once you have deleted all keys, it is now time to close the regedit program and move on to the next step.

======================================


Other problem here... cannot find HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\Cla ss\\DISPLAY

on my WinXP HTPC. Any suggestions?


5). You will now need to go into your system device manager, which can be accessed in two ways. One, by right clicking on My Computer, clicking Properties, and then Device Manager in the following window, or you can access the device manager in your system Control Panel and double clicking on the System icon, and clicking Device Manager in the following window. Under Device Manager click the plus symbol next to Display Adapters, you will now see the Standard PCI adapter listed below. Highlight it and hit the delete key on your keyboard and click yes to confirm when Windows prompts you. It will then ask you to reboot your computer to finish removing the device, click no. Next step.

===========================================


Done on XP as well



6). Extract/Unzip/Decompress your Radeon drivers of choice to a location which you will remember (I use C:\\Windows\\Desktop\\Radeon). Once you have extracted the drivers, you can now reboot your computer to manually install them. I do NOT recommend using the ATI setup program to install drivers. When you reboot your computer, Windows will detect new hardware and ask if you wish for it to search for drivers. I always tell Windows where to search, and do not recommend you let Windows search automatically. Since Windows 9x and Windows ME vary slightly in this driver install process, I will assume you are familiar with basic driver installation and can handle pointing Windows to the directory which you extracted the drivers (i.e. C:\\Windows\\Desktop\\Radeon for 7041 whql or C:\\Windows\\Desktop\\Radeon\\ATIDrive for all other driver packages). From here you may proceed to let Windows search the specified directories for the .inf file containing the driver install information, and the rest should be fairly self explanatory.


=======================================

Extracted the drivers, but XP never asks me for anything, goes on about its business and reinstalls some version of the ATI drivers (I guess the ones that come with the package....)


Furthermore, anytime I remove the driver and reboot, when PowerStrip pops up, I get a serious sytem error, with blue screen and memory dump.... have not tried to remove PowerStrip, will let you know if that makes any difference.


Questions:

1) Anyone knows how to prompt XP to install the driver I want after removing the old one?

2) Anyone knows where the

HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\Cla ss\\DISPLAY

has moved to in the wonderful WinXP world?


Thanks!

Your post sounds hauntingly similar to my recent experience with W2K drivers - http://www.avsforum.com/avs-vb/showt...threadid=92978


I couldn't find that registry entry either. I am presuming that it only exists for W98/ME not W2K/XP, unless I hear otherwise. I also had problems with W2K starting the new driver installation without asking where to get it from. I eventially got it to a point where it prompted me for a file that it couldn't find and I redirected it to my install directory. How I got to this point, I don't know. I probably rebooted 40 or 50 times. Very frustrating..


My only suggestion to your process is - Yes, uninstall PowerStrip as well as the ATI driver. I believe it does get in the way. Also, don't change to VGA mode manually, it got me into trouble. It seems that when uninstalling the ATI driver, it will automatically switch to VGA mode on the next boot.

When you find a way to prevent XP from re-installing a updated driver, let me know. I tried every trick in the book that usually works prior to XP, but no go now. So I had to do a fresh install of XP to go back to a older driver. I guess XP thinks it is helping me?


Best thing, do a "system state backup" if you use XP pro, then you can restore back to earlier drivers if you screw up. The "System Restore" thing hardly ever works when you need it most, so backup instead.

I had same Problem. I followed the "how to" But on reboot Win xp reinstalled it's drivers. ( with those drivers my accessDTV desk top window was garbled.)

I just ran the new driver install ( over ) the old . I had No problems and Access DTV works again.

I don't use power strip.

Running NEW over OLD is no problem, but try OLD over NEW. XP will still use the NEW drivers even though the install looks ok. Check the driver date being used, it will still be the NEW driver date.

You never said specifically that you did this only "every trick in the book" so I will ask. Did you try the "Roll Back Driver" button for your video driver in the properties>driver of the device manager? It claims to do just what you wanted.

I never needed to use that feature ,yet.
