I had to uninstall Service Pack 2 as it failed half way through install. Ever since then I when I switch on my laptop it says that new hardware has been found then tries to install Compal E-POWER Driver, then it can't find a file called HKDRV.sys and fails. It doesn't seem to cause any problems and I don't even know what a Compal E-POWER is or does so if no-one knows what the HKDRV.sys is then could someone at least tell me how to stop my laptop trying to install this new 'hardware'. Unless someone can tell me its very important? Thanks v.much
