Standard 101/102-key or Microsoft Natural PS/2 keyboard: Code 19

[George]

I run Win XP Sp3 on a Compal FL90 laptop. The problems started when my Avast
AV flagged us30kbd2k.sys as a Trojan and placed the driver in quarantaine. I
restored the driver, and the us30 service seems to be working again
correctly. But, from this moment on, nor keyboard, not touchpad are
responding under Win XP. The fact that the keyboard works fine under MS DOS
tells me that it is a Windows issue. Going to the device manager, I noticed
that the Standard 101/102 key was flagged (FL90 has 101 key emulator), with
the properties giving me a code 19 (hardware device can not be started
because ... registry information incomplete or damaged). I uninstalled the
driver and automatically, Win puts the Logitech PS/2 driver, telling me that
this is the best match. Unable to find the original driver (nor web, nor
installation CD), I extracted the driver from another Win XP system, and
reinstalled it. The code 19 however remains.
As the keyboard is linked to the BIOS, I updated the BIOS to the last
version (v1.19). No result.
I ran Easy Registry, Advanced System Optimizer, TuneUp Untilities 2008. No
result.

An extreme solution would be to do a clean Win XP install, but, I would like
to keep this option as last solution, and rather get to the source of the
problem (Would take me weeks to get the laptop reconfigured).

I would appreciate very much if someone could give me some advice on how to
cure this code 19.

Thanks in advance,
George

I done the last resort and guess what .............keyboard working again but
only after putting in stand by then restarting ............and touchpad still
no life ...............and thats after two clean installs with two formats
per install .This is due to a human interface ideacom update and obviosly a
service pack issue ..............how mad am i ?
