Okay...I've been out and bought a USB keyboard today, so I'm working from my Dell laptop again
Firstly, I looked for the CCleaner backup file, but it is nowhere to be found (I DEFINITELY chose to backup my registry when prompted during the clean!!!)!
Then I did a system restore from a point immediately prior to the clean, but this made no difference.
I then looked at Device Manager to check for exclamation marks, with the following results:
Standard PS/2 keyboard [built-in laptop keyboard].....code 39
Dell Touchpad.....code 39
Broadcom Netlink Gigabit Ethernet.....code 19
[cmz vmkd] Virtual Bus.....code 39
Microsoft System Management BIOS Driver.....code 19
I believe code 39s are driver issues, so do I try to track these down on the Dell web site? (I also have the original driver DVD that came with the laptop).
However, code 19s refer to registry issues, so I am sure that CCleaner caused these. Will a driver repair / reinstall fix the registry issues? Or is this more complicated?
Finally, I am a little concerned about the "Virtual Bus" issue, as it is not simply a driver that I can reinstall, so I don't know how to fix this.
Any help would be appreciated greatly.
Thanks
