Solved Can't Access NVIDIA Control Panel

Kotuku

Power User
All of a sudden (probably started 10+ days ago) I can't access the NVIDIA Control panel, I get an instant error message, as per attached. I am running 175.16 driver and I can't install newest driver as I need to access the NVIDIA Control panel so I can set up dual monitors.

I can't even run Driver Sweeper, it leaves 3 files behind and I don't think it does an uninstall.

HELP!

Thanks Shawn, as I have NVIDIA MoBo etc, my Prog & Features shows 5 entries

NVIDIA Drivers
NVIDIA Forceware Network Access Manager
NVIDIA Performance
NVIDIA System Monitor
NVIDIA System Update

The first two show nothing in the SIZE column. Now it would seem the first is what I need to uninstall, yet I don't want to remove all my MoBo drivers etc. It is not specificall there anything that says Video Drivers
I think I may have a bum installation of the 175.16 drivers? Maybe I should first re-install that.
Can installation of the Video drivers be done in Safe Mode to make sure nothing interferes, or is it better in normal?

Thanks
Frenchy

Hi Frenchy,

It would be the NVIDIA Drivers entry. It can be uninstalled in Safe Mode if you like, but it should not matter.

Hope this helps,
Shawn

OK, When I Uninstalled the Vista Drivers, a screen popped up to give me the option of what driver I wanted uninstalled. I did that and installed 175.19 and that still would not let the NVIDIA Control Panel start. Uninstalled that and back to 175.16 but still will not allow control panel to run, with an APPCRASH error. I am stuck!

When you uninstall the drivers, get there though the "control panel home"/choose uninstall a program, choose nvidia drivers/click "remove only the following"/nvidia display driver, this will also take you into safe mode at which point you would also use driver sweeper..."while still in safe mode" choose/nvidia display/choose clean/driver sweeper will now remove the rest of the display drivers entries, then restart and install new driver.
Once you restart right click on desk top and choose nvidia control panel/choose advanced settings/let it adjust resolution if needed. It should be there now, if not you have other problems.

Thanks for that, that was 'slightly better', but no solution! The trick was I needed to run the Driver Sweeper as an Administrator other wise it didn't do its thing. All files removed and I installed 175.19 and a clean install but again the NVIDIA Control Panel didn't start and failed with an APPCRASH. I uninstalled 175.19 cleanly and installed 175.16, again same problem and the error code is for the APPCRASH is

If anyone can interpret that, I will be eternally grateful. I have Rollback Rx on board, so I take a snapshot before any of this and then roll back when it fails.

OK, I bit the bullet and rolled back my system to 29 Aug. That solved the problem. Unfortunately I have no idea what caused the problem as only normal Windows Vista updates and a quick install and uninstall a few days later of Google Chrome. I have re-installed the Vista Updates and the problem has not re-occurred.
This problem went away (I have my Control Panel back) plus a few other niggles, like not able to create a restore point. I had installed Rollback Rx earlier in August, so this REALLY saved my bacon! I have to say this program is a God send when doing Video driver installs that don't work and a few seconds later able to revert the system back. However, this ain't a plug for that program, just reporting the problem solved.
