Hello, I recently reinstalled Windows XP sp3 on a friend's computer and every time the Windows gets loaded up the keyboard will stop working. I went into device manager and saw an issue with the keyboard driver stating that it could not start. If I either try updating the driver with the same driver or uninstalling and reinstalling the driver the keyboard will work until the system reboots. Keyboard works in BIOS and tried a Known Good keyboard and has the same issues. The windows CD was used to install windows on a different system, my friend has a valid product key for Windows XP for each system just one disk, and that system has no issues. The OSRIs were needed due to virus issues on each system and had both HDs wipped clean with long formats and a HD wiping software. The trouble system is a generic local built system with a Gigabyte GA K8N Pro SLI motherboard.
