Windows no boot after driver update

[Guest]

Hi all, 
So yesterday i was at my partners work trying to get a second monitor working with their AMD crossfire setup. Don't ask me what card it is as i can't remember off the top of my head.

Any way i downloaded the latest AMD driver through the auto detect hardware from the AMD website and installed it, Half way through the update it decided to blue screen. Unfortunately i didn't grab the error code but i dare say it would had been from the driver. Once the computer restarted it would just hang at the windows 7 splash screen and wouldn't progress. At first i thought it was just a random glitch so i did a force restart. It happened again so now i am shitting bricks. So i restarted the PC again and tried to run windows restore as i created a restore point before doing the update but the restore option wasn't letting me run it from the windows 7 pro OEM CD they had. (i didn't have any of my tools or software with me. ) Once that failed i than tried to get the computer in safe mode. I selected safe mode with networking (once i got the options to show up) then it hung on there also and while looking at the screen the graphics went funny at the top of the screen and the system restarted. 

I have spent over 8 hours now trying to work this out in a virtual environment and try to do a manual restore through WINPE via command line* and i just can't seem to get any where.

This option causes more issues so i can't use this as a way around. 


One thing i would like to try to do is remove the graphics cards and connect through onboard graphics. From my understanding this should by pass the AMD drivers as they are not required. But the misses is a little stressed about the issue as this is causing massive down time at here work. 
Would another thing to try is to remove the driver file from system32\ DriverStore?

 

I would have not updated the driver if i new this would happen. I have done many updates in the pass with no issue like this before. I do it all the time in my current role as an ICT tech. But the difference is we have base images so if shit hits the fan we can just re-image the machine. 

 

any help on this would be great. 

Note: I am not at the computer at this time and most likely wont be able to get to it as the misses does not want me to go near it any more (which has put massive guilt on me and has caused me to doubt my skills and throw in IT all together.)

UPDATE:

Looks to have been resolved now. 
System tried a windows repair and failed. From there we were able to get to the restore point. Restore the machine and than windows updates caused some little but now is good.
