I have spent 12 hours trying to fix this problem. I am working on my sister's machine and really would like to get this running without formatting the hard drive.
Here is what happened.
Yesterday my sister asked me to remove some malware from her machine. I used malwarebytes to remove a browser object helper spam. The machine restarted and booted into windows perfectly. At the same time I decided to update some of her software and drivers that were years out of date. I installed the newest AMD Catalyst Driver 14.2 beta. I did not uninstall the previous version (out of share laziness) and now the computer will not enter windows.
It will hang on the Starting Windows (Black screen). It will not enter safe mode (freezes after loading atipcie.sys).
I have tried using a windows installation disc to repair windows. It does not work. It states it cannot fix the problem. In the error box it shows bad driver.
I have tried sfc /scannow and it states no problems.
I have tried chkdsk /r and it finds no problems.
Where do I go from here? I really do not want to have to start again and reinstall all her programs.
Any help is greatly appreciated.
PS. I can add her drive to my PC to get at the files if necessary.
