nvidia driver update failed

[negis]

Hi,

About last week I update my graphic card driver (nvidia geforce go 7150m/630m) from ver 7.15.11.5665 to 7.15.11.7991 using updating function in Device Management. The update when smoothly and I thought at first that it's successfull since I did not receive any error messag and in Device management list the new ver. as 7.15.11.7991. However, after that I got some conflicts in driver and it somehow affects my cdrom drive as it's now no longer start when turn on the laptop unless restart immediately.

I went to the regedit and see in the installer folder of nvidia, the install regitry listed as "failure" and the version is still listed as the old one (7.15.11.5665). Is there any way to correct this?

BTW, my OS is window vista home premium 32-bit.

Welcome
If you have the new driver and are having problems, go back to device manager and roll back to the old driver. What you are experiencing is a common problem. Many here feel it is best not to upadate unless you are having problems.

Edit: Better to roll back with a system restore.

My restore point for that time is long gone, unfortunately. I did try roll back driver but nothing happen. Just a moment ago, I uninstalled the current version in device management and try installed the old one I had before updating but unsuccessful. After uninstall and reinstall, my computer had no nvidia driver for configure. The install registry in the nvidia installer folder in regedit was listed as failure and no version installed. I have to do system restore just now in order to restore my graphic driver back.
I think there's something wrong with the nvidia registry now

It appears that there may be a problem with the registry. If you have no restore points and you did not save your registry settings, there are problems.
Not much that can be done if your registry is screwed.

Is there a way to clean/correct the registry? I have just reinstall my OS after the corruption about 3 weeks ago so I don't want to format it again

You have a Vista DVD?

 

[negis]

No, I only have recovery discs

 

[richc46]

There are not many ways to fix registry, unless backed up
System Restore
Reinstall of Operating System
Repair install, but a CD is needed. Can you borrow one?

I have update to SP2 so if I use one, is it ok?

 

[richc46]

If you have an SP2 CD and your OS is SP2, you can use it. It must be an install CD, not just an image of what was on your computer when you received it.

 

[negis]

No, I mean most install DVDs are w/o service packs so right now I've updated to SP2, is it ok to use 1 w/o service pack?

 

[richc46]

For repair install it must be the same sp

About the registry, in the installer folder of nvidia, registry install REG_SZ listed as failure does it mean the whole registry has problem or just indicate a fail install? Because my display still function well beside the cdrom problem so is it need to be repaired?

 

[richc46]

Registry do not go bad all at once. Usually just portions at a time. I think its just that one area that is corrupt.

I don't understand. Why does the registry lists status install as failure but both msconfig and DM list nvidia graphic driver as the new version and it appears working fine? And during the update/installation, I did not receive any error.
