Windows can't find my Liteon 411?

My Liteon LDW 411S has been performing just fine till today when I went to play a pc game and it wouldnt load…niether will a dvd or cd…in the control panel this message appears with reference to the liteon

“Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41)”

I know that I have probable done something stupid being a novice but is there anyne out there whp can tell me how this has happened and more importantly how to fix it. I am running XP if that makes a difference.

Thanks
Allan

Try uninstalling the drive in device manager and rebooting.
If that doesn’t work, try uninstalling the entire IDE chain and reboot.
If that doesn’t work, try the drive in a different PC with a different IDE cable to determine if it’s a hardware issue.

You can also right click on my computer and select ‘manage’. Then go to ‘Disk Management’. If the drive shows up there, try to right click on it and change the drive letter that XP has assigned to it.
