green screans on some videos on Alien Aurora R4

What do you mean Windows blocks the new driver from installing? You need to tell Windows to go lay down

You need to do a full uninstall of the drivers, clean it and then reinstall new drivers. Don't trust what PC Checkup, System Mechanic and anything else says. You got a problem, right? Yet they say no? I would uninstall them and never look back. Stuff like that is kind of junk IMHO.

Try this.

Go download CCleaner and install it. It's free: www.piriform.com/ccleaner

Download your new drivers ether from Dell or Nvidia.

Go to Device Manager. Find the Display Adapter tab. Find the GPUs and right click. On the next window click uninstall and check the box to remove driver.

Don't reboot yet. Run CCleaner. Go to the Tools Tab and see if you see anything that says Nvidia. If you do uninstall it. Then go to the Registry Tab. Click the Scan For Issue Tabs at the bottom. Back up and then fix everything it finds.  

Now reboot in safe mode. You do that by hitting F8 on the BIOS screen. Once on the desktop run CCleaner again and do it all over. If it finds something then nuke it just like you did before.

Now reboot in normal mode and install the new drivers.

I can't say if this will fix the green screens but it's a start in the right direction.

After all that, Nvidia would not install and said it was wrong version on windows. Asked to install off web and 8.17.12.9573  2/09/2012

Go figure why would this driver update be listed for my Service Tag if it doesn't work?

The Dell download page is all messed up. That could be why. If it was me I would try the Nvidia driver first. It would be good to see if it works because Nvidia updates their drivers much more often then Dell. The Dell driver is already outdated.

This is the one that I find on the Dell site for the R4/Windows 7 64bit: http://www.dell.com/support/drivers/us/en/19/DriverDetails/DriverFileFormats?DriverId=95C05&FileId=2794363599&productCode=alienware-aurora-r4&urlProductCode=False

This is the one from Nvidia: http://www.nvidia.com/object/win7-winvista-64bit-296.10-whql-driver.html

on Nividia driver detect: 2x GeForce GTX 555

This product has been detected as your primary device

2x GeForce GTX 555

This product has been detected as your primary device

A driver cannot be found for this device

I don't have the green screen on some videos any more but can't see Nvidia control panel, SLI etc. since cleaning all the Nvidia files with CCleaner.

* Download/Install the latest Microsoft .NET Framework http://bit.ly/a7T3ZV
* Restart the PC when done
* Disable Microsoft Security Essentials or any other Anti-Virus Real-Time Scanning
* Close the Nvidia taskbar icon (if present)
* Uninstall the Nvidia Driver and PhysX from Control Panel- Programs and Features
* Restart the PC when done
* The Microsoft default driver might load. That is fine or just click cancel to New Hardware found
* Download, install, and run Driver Sweeper http://bit.ly/xvbFOz
- Select Nvidia Display and click the Clean button
* Restart the PC when done
* When it comes up this time:
Aero might be off
Main Monitor drivers or profile might be missing
Resolution is not set (make due for now)
* Run Driver Sweeper again to check (Nvidia Display - Analyze, it should list nothing)
* Restart the PC when done so the driver install starts on fresh boot
* Disable Microsoft Security Essentials or any other Anti-Virus Real-Time Scanning
* Download and install the Dell OEM Nvidia driver http://dell.to/IuEPgR
* Restart the PC when done
* Monitors and proper resolution should be detectable now
* Open the Nvidia Control Panel and check orientation and resolution for all monitors

Chris, I am still getting Nvidia Installer Cannot Continue, This nvidia graphics driver is not compatible with this version on windows. The graphics driver could not find compatible graphics hardware.

Maybe I have done something wrong?

In divice manager:  Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

What happens if you go into Device Mangager, right click the GTX 555 and select Update Driver Software? Try that real quick. If that does nothing then just uninstall from Device Manager again. Don't worry about trying to clean everything. Just uninstall,reboot and let Windows install the driver. Once that is done then reboot and try to install the Dell driver again.

Got a question. On the GTX 555 cards. Do both of them have DVI outputs or is one of them plan with no outputs at all on the rear of the card?

In divice manager:  Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

Wait, that is the old driver that was originally installed? Is that what you intended Chris?

Yep, still have the gree video screens in the same places as before.

O.K. I went back and changed only one thing...I used download manager to download the driver and it installed Driver date 11/3/2011 8.17.12.8576    Apparently trying to down load a singel driver w/o download manager doesn't work well.

Now to check to see if I still get some green video.

O.K. What I did was go back on Chris and redid the directions and used the link provided:   http://dell.to/IuEPgR It was downloaded and saved then run. the driver version I listed is what it installed.  IDM? 

You use IDM? Disable it when you install the driver. Also are you truly installing the driver or do you boot up and let windows do it? What did you mean by " it installed Driver Date yadda yadda "? I'm starting to think this could be a user error. Can you explain a little better how you are installing it please.

O.K.Yes I have Nvidia control panel now so I used it to up date, following your instructions the installed drivers are 2/29/12 version 8.17.12.9610 Nvidia Drivers 296.10 WHQL. That is the suggested driver control panel gave me for my GeForce 555 GTX. I'll go to the known sites I have been having problems with to see if I still have green screens. I need to check to see is SLI is set correctly first.
