Windows 7 Snafu

I have a Window 7 Dell Optiplex 760 machine that I wanted to switch to an identical machine but with a dual monitor video card installed in it.  I downloaded the drivers for the video card, but did not run the setup. I removed the hard drive from computer 1 and installed in computer 2 thinking it would at least boot up in a vga mode.  It failed to boot, making half way through the startup.  I then went through the process of trying to do safe mode boots and LKGC to no avail.  I then tried do the Startup repair, no good.  I then put back in original box and it booted fine.   I then ran the setup for the new video driver, then tried in system 2 again with no luck.  Now it will not boot in system 1 either.   I then thought I may have installed an XP driver instead of 7.   I cannot get this machine to repair itself, windows does show a BadDriver  problem in the info screen.   Going to a previous restore point does nothing either.  

Any help????

You say they are identical ... both OP 760, with IDENTICAL hardware?  Were they purchased at the same time, or some time apart?  If apart, it is possible that the board was upgraded and is using a slightly different chipset to manage drives.
Put the hard drive back in the original PC and boot in to VGA Mode (on the F8 startup menu).  Then uninstall the new video driver so you can (hopefully) boot normally.

Once you get that fixed, use SYSPREP to prepare the hard driver for transplant.  This can be found in c:\windows\system32\sysprep.  Select the "Out-of-Box experience" and "Shutdown" options, do not select Generalize.  After this completes and the computer shuts down, you can then move it to the new computer and it should auto-detect all the hardware.

They were purchased at the same time, and were identical except for built-in video adapter vs the ATI daul monitor adapter.

Cyberlopez,

I assume you mean "Enable low-res video" the new VGA mode?????  No go.   Safge mode is a no go too...
Can you remove the adapter card and use a built-in video?
Do you get a Blue Screen error by chance?

Here's a good document on troubleshooting drivers:  http://support.microsoft.com/kb/330182
I would look at "Method 5" and use that procedure to remove the driver you just installed.

When i tell it not to reboot, i do get BSOD with a STOP 0x0000007b error.   I did not try taking out the card since that is in system 2 and i am now trying with system 1 which only had built-in vga.   When i did try yesterday to use the built-in (i did not remove card)  i got an error message from BIOS about it.  I may remove the disk and connect to a good machine and try step 5, but that documentation was for XP.....

0x7b is a storage-related problem - usually the driver.  Can you boot to the second machine if you take out the graphics card?  I would bet no.
Can you boot into the Recovery Console?  The drivers are in same folder on Win 7.

Not sure what is up.   I did a full check disk on the drive while connected to another computer and it found nothing wrong.    

AS far as removing the drivers, i cannot fins the ati drivers in the system32/drivers folder.   I am trying to determine which might the the bad driver that does not have the 7/13/2009 date....

You would think safe mode would allow me to do this.   I tried a reinstall over the current installation by boot to the dvd to save my documents and programs, but it wants me to start it within windows.   MS making things easy again.......
Wow talk about strange....

I decide to use computer #3 same batch of 760 with built in vga.   Booted up fine.  Installled Dual VGA card, booted fine, installed driver rebooted and i am running all good......
