Hello Franck_crea Have you made a system restore so that you have a bootable windows? If you can boot to windows, here are some directions how to remove drivers. You can uninstall HP quicklauch button software from control panel if you have it installed. Keyboard drivers can be uninstalled from Device manager. Here is a pretty good tutorial how to do it. http://www.tech-forums.net/pc/f127/removing-driver-within-windows-7-using-device-manager-246852/ Disregard the Nvidia part... Remember to check "Delete the driver software for this device". You may also need to force windows to show disconnected devices to be able to remove all keyboard driver instances. Directions here: http://www.petri.co.il/removing-old-drivers-from-vista-and-windows7.htm Check before and after driver uninstallation whether you have HpqKbdFiltr.sys attached to your keyboard driver from driver properties. When uninstallation is succesfull, windows will install its' standard keyboard driver and HpqKbFiltr.sys is not attached to it. There may be also other keyboard devices which may or may not have that Hp driver attached. You must uninstall all of those which have it. BE WARNED! If you do not know how to do this right DONT DO IT! You can mess up your computer pretty badly when removing drivers. Do backups first! Ask if you need any more info. I'll try to answer. |
