Hi, Ok bit of a longwinded problem here goes...

The original task I was trying to perform was to fix system DLL files using SFC /scannow.
During this process, I was asked to insert Windows XP (My OS btw) -CD2. I already had an Installation disk in the CD drive.
So I googled it. I came up with this website and advice.
My search for fixes
I followed the advice to the letter. I copied the I386 folder from disk to my root folder (C:). Then, I went into Regedit, path = HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Setup.
I modified the sourcepath here from C:\Windows (I really hope it was this, i told myself to remember the original path, but my mind is playing tricks on me a little, sorry)
and changed it to C:\ and rebooted.
When the GUI had loaded, the resolution was a mess as was the color bit. So I tried to reverse the situation in Regedit and reboot. Still the same.
OK, I thought, I shall reboot in VGA mode (never done this before, thought i'd give it a shot) still the same.
OK, i'll just update the video driver right? When you go to the Display app and try to change the resolution etc, you get this message.

'The currently selected graphics display driver can not be used. It was written for a previous version od windows, and it is no longer compatible with this version of windows.
The system has been started using the default VGA driver.
Please contact your hardware manufacturer to get an upgraded driver, or select one of ther microsoft provided drivers.'


So, OK. Ill update the video driver. I have a lowly little onboard ATI radeon X200 for this PC. I go to the ATI website and download the driver.
Upon install, I get this message - 'Setup was unable to complete the installation. Try to setup your display adapter with a standard VGA driver before running setup'

Next, I goto System restore. Now, i thought system restore was setup correctly on this PC. However, it does not give any restore points to me whatsoever. SR is something I have not used for a couple of years on this PC, but I was surprised. Perhaps this is a symptom of changing the registry key?

I have also tried a boot to the last known configuration. No dice. Whilst typing this I have thought of the idea of googling for a standard VGA driver and downloading & Installing. I will keep the post updated if this provides a fix.

I really dont want to have to do something like a clean install or factory restore. Is there some way I can fix this? And more importantly what can you teach me?

Also, when I can get my display driver back online, I think I shall post about the original problem of fixing DLL files. :thumbsup:

If you have or can borrow the installation CD for your specific operating system, you can perform a repair installation. This should repair the corrupted files and not affect your data or non-Windows applications.

What ever non-native drivers you need will still need to be installed.

It usually is helpful if you post the make and model of the computer that you are posting about.

If it is a custom build, posting the make and model of the motherboard is a good start.

A second thought. When you get this problem sorted out you should create a new restore point for System Restore.

@dc3.
Yes a repair installation is something I have thought of as well. However, i've never actually performed one. Do I go into the recovery console and press R for a repair installation or do I go into the setup option and choose to repair in there? If so the second option will not work as I am not given the option for repair in windows setup.
If i do go ahead in the recovery console, should I back up files?

Ok. I am currently backing up data to another drive before I continue. Can I please confirm - I am trying to manually restore the registry with a repair installation is this correct? I may need extra advice once my data is backed up and I begin the repair install.
Thank you 4 your help so far.

Obvious fix alert! It was a driver uninstall I needed. The standard VGA driver then kicked in, allowing me to re-install the new ATI driver. Thnaks all for help.
