Hi all, I've narrowed down the problem and solution, but I am curious of the method.
I've recently unistalled my display drivers (because I was going to update them), and after the reboot, my USB devices (keyboard/mouse) will not work at the Windows logon screen. I've been reading this is a known issue.
Here is where my problem is, I can't do a system restore because I don't have it setup, and I really won't/can't format. (stupidly only have 1 partition with lots of valuable data on it)
I'm really just interested in manually installing the USB controller device that my display drivers somehow uninstalled. (I think it's related to the chipset).
I have access to the cmd prompt in a weird repair mode that I've been able to access, that does have keyboard and mouse support. So I'm just interested in getting Windows to recognize the keyboard/mouse at the Login screen so I can actually access windows.
Any help would be much appreciated.
EDIT: The USB mouse/keyboard will work for BIOS, but the second the windows loading screen loads, the sensor for my mouse and the light on my keyboard turn off, and is not recognized until I go back pre-windows load. If I can just get past the logon screen, windows would do it's "new hardware recognized" thing. But I am stuck at the logon screen.
EDIT2: I'm running a AMD 785G chipset. I uninstalled Catalyst 12.3 to upgrade to the latest. on an AMD HD6950.
I have booted into safe mode, and the same problem arises. No USB support. I really just want to get the generic USB driver, and install it manually through the CMD prompt. I really don't know what the generic USB driver would be though. I'm thinking about going installing an old HD, and installing windows on it, backing up all my data from the other HD, then just formatting and starting over. I just wish I could back up my files without having to go through all that...
So since I've only got 1 drive and 1 partition, I'm thinking about hooking up an old hard drive, and installing a good version of windows on that drive. Then I will boot to the good windows install and backup the files I need to the newly inserted HD, then format (while creating multiple partitions so this never happens again) the current HD and just start anew. I shouldnt have any problems dual booting 2 copies of windows should i?
Thanks for the reply again, I do not have the OS' disk, its only a restore partition on my drive. My only option right now is to format without backing up any files.
As of right this moment, I'm copying over the files
hccoin.dll to windows/system32
I tried installing another drive, that i was going to reinstall windows, get a bootable machine and then copy the files i wanted to backup then format the original drive....but it's an old IDE hard drive. I even went out and bought a PCI connector that has an IDE slot on it. I kept getting x7b BSOD errors which are known to be "hard drive" errors.
Well actually, I didn't copy the usbport/usbehci/usbhub.sys files into /system32/drivers because they were already there. I didnt' want to overwrite them. Hccoin.dll was not in system32 though. So I added it just in case.
