After trying to uninstall AMD's Catalyst Control Center, I realized I deleted my USB Drivers during uninstall. What happened is I did an Express Uninstall instead of a Custom Uninstall. I was only supposed to uninstall my Display Driver and the CCC. Apparently, in that Uninstall, there was an option to uninstall something called AMD USB Filter Drivers. So, I have a computer that boots perfectly into Windows but cannot login.
Note: The Mouse and Keyboard works during the Windows 8.1 Advanced Start-Up Menu.
With that limited functionality, I've tried the following:
1. Plug Mouse & Keyboard into different USB 2.0 Ports & USB 3.0 Ports, but all remained the same.
2. I tried two different System Restores. One was when I uninstalled AMD's Catalyst Control Center, and the second was from July 9, 2014. Both restores failed due to Windows being unable to access a file.
3. I tried booting into Safe Mode w/ Networking, but, surprisingly, nothing happened.
My last option is to Reset my PC to factory settings--which means I'll lose 600GB of data-- or attempt an OS repair. However, I do have HP Recovery disks. I bought them last fall, and they come in 4 disks. But, the Recovery disks are for Windows 8 not 8.1.
My question is, Is there a way to Repair Windows (NOT RECOVERY, BUT REPAIR) with the recovery disks despite them being for Windows 8 and not 8.1, or will I have to buy a disk from Microsoft? And if so, will Repairing Windows reinstall basic USB drivers for login?
If it works you're back in business. You will lose third party desktop applications and must reinstall but personal data will be retained.
If you recover you can also create a custom refresh image of your PC after getting it setup the way you prefer. When refreshing your PC in the future you only have to reinstall any desktop apps installed after creating the image.
You also can create a system image on an external drive anytime you like from within Control Panel - File History. Check the lower left corner of the File History dialogue box for "System Image Backup". You should then create a Microsoft Recovery drive. Instructions are here. You can restore a Win 8.1 system image with the recovery drive.
There are also many good third party imaging solutions available.
Unfortunately you cannot repair your Win 8.1 install with HP's Win 8 recovery discs. If you have to use that method you will lose everything. You will have to rebuild your Win 8 install back to Win 8.1.
As a last resort prior to an HP factory recovery, you may want to consider this option to recover data.
