Resolution changes upon restart

For the past several days each time I reboot or power off/on my resolution will switch from 1920X1080 to 640X480 or 800X600. The boot goes well, desktop looks fine then it "blinks" and voila! the resolution changes.
I just changed from an ATI to nVIDIA GPU and the resolution changing remains. Kinda spooky.

Yes DF I uninstalled ATI drivers and CCC, ran CCleaner and Tuneup registry cleaner before powering off to install the new nVIDIA GTX460.

EDIT: however I did not reinstall nVIDIA drivers but Windows update had a newer one and the problem remians.

The Windows update version won't allow you to use Nvidia control panel.

I installed the same one you did for my 460. Was going to make Snips to show you and Nv control panel would not open.
So I just spent the last 20 minutes un installing the Windows version and installing the newest ASUS/Nvidia driver.

I would suggest the same. Use the latest from MSI or direct from Nvidia. Ooops MSI!
Everything is fine with mine now that I got the right driver.
ASUS happened to have the March 2011 driver so I used it but the one from Nvidia website will work also.

If resolution is still wrong after installing the new driver right click desktop in open area then click Nvidia control panel.
Snip below shows Nv control panel. These are my settings. Ignore them.
Select your resolution if it does not select the right one automatically.
Make sure 32bit color is selected- if not already.
Yours will probably be 60Hz- 99.99% are 60Hz.
Mine is an unusual at 75Hz.

When the Nvidia Windows Update reappears just hide it.
After I installed the new Nvidia driver Win Update still wanted to install its own version. So I hid it.

Hope that helps.

Newest driver from MSI or Nvidia.

I typed in Gigabyte above the first time.

Select your version. Not sure from your specs if yours is 460 or 460SE.

Mike, I wondered where "gigabyte" came in, maybe my mobo, LOL
I have completely uninstalled all ATI left-overs, uninstalled and deleted all nVIDIA drivers than tried both the drivers mSi has and also from the nVIDIA site. Probelm remains but is mostly changing to 680X420 now. It's got me stumped.

Oh I did flash my BIOS to a newer version to be compatible to a 6 core CPU. Maybe that's it.

I ended up going to the Nvidia266.xx today from Nvidia.
Asus was still an old one.

You should be able to go into Nvidia control panel I posted earlier and set it.
At 1) in the window it should show monitor.
Then you set what you need and it "SHOULD" stay set after reboot or shutdown.

I'm not sure what is going on.
I will post if I find anything else helpful.

This is just to double check your driver against what I installed today.
Should be the same. We both are using Win 7 64bit .

Device Manager> Display Adapter open it then right click Nvidia GeForce GTX 460 (that is what should show)> then click Properties.

Then click Driver tab.
Yours should be the same driver as mine.
Same model card should be exact same driver. Nvidia doesn't care about brand name of card.

Try saving the screen resolution as a profile.
Normally, the profile loads when Windows starts.

Thanks Mike, I did have the nV CP installed but it was changing my carefully adjusted colors and contrast. After losing thier CP at least the colors etc. will stay set. Yep, my driver is the same one you have.

@ p5bdkw, how do I save the resolution as a profile? I've never had ocsasion to change that area.

Thanks friends!

In Hopalong X's first screenshot, if you look up at the top you can see Profile. There should be a save setting within. :)
