Usb ports do not work after uninstalling AMD drivers *Need more help*

[evans74]

I have read the other threads and have tried to diagnose this problem, but I am having no luck. I got a new graphics card and went to uninstall the previous AMD graphics card drivers so that I could start fresh. I accidentally did an express uninstall, and now I have lost all of my AMD drivers and am not able to use usb ports. I am currently remotely accessing the problem computer through my laptop. I have tried running sfc /scannow as an admin but at the end of the scan I get a message saying that it could not repair all problems and to check the log file. I have tried to download the drivers form the motherboard support dvd, but I get a large error screen listing a bunch of errors and missing drivers and what not. I have tried going to AMD's website and Asus's website to redownload Catalyst and the usb and chipset drivers but every time I reboot, I am in the same place and nothing seems to be working. I have not set up a system restore, so I cannot restore to a previous point in time. I have also inserted my Windows 8 OEM disk but it tells me that it is not valid, which is weird. The last option that I want to do is completely reinstall the OS and lose all of my data and information. Is there something that I have not tried yet? Motherboard is an Asus Crosshair V Formula Z

download these newest drivers see if they work.

if not unzip them to the hard drive then go into device manager and one by one hit driver update and point windows to the files on the hard drive.

Half way through an error message appears saying "install package failure". When I check the log file, it says that the 'catalyst control manager' failed installation

try this use an ati drive sweaper see if there part of the driver left that still running. or try booting up in safe mode if you can.

I booted in to safe mode and used the ATI driver sweeper. It did it's thing and when I went back to look at the local drive C: there was still several AMD folders with all kinds of files. Should it have deleted those files?

 

[smorizio]

yes i would and see if you can install the drivers in safe mode.

Should I run the ATI sweeper and then go back and manually delete any remaining AMD files on the C: drive and then try reinstalling the catalyst?

I have finally fixed the issue. I rechecked system restore and I did not see a tab earlier that listed update restore points. The last critical update that was listed was one from last month, so I restored to that point and every issue that I have had so far seems to have been resolved. Thank you smorizio for all of your help, I really appreciated it.
