Easynote SJ51 DVD drive problem

Hi, I have a Packard Bell Easynote SJ51. It comes with the dvd drive Maa UJ-870. One day the DVD stopped working. It wasn't even recognised in Bios. On the CD ROM entry in the bios it was None, and i couldn't change it. Although the Bios doesn't detect the device it is detected in device manager in Windows but with an error code 10. I have tried all the scenarios about uninstalling iTunes or recording software (neither was installed), deleting upper and lower filters in registry (neither was there) but nothing. One hint is that the drive's name in device manager isn't correct. It has some random characters like @$#$%... This usually happens (on desktop pcs) if on an IDE channel you mess up the master and slave devices. But here there isn't such a thing. Only one device on Ata, two Sata disks, and no configuration option either. Also,it happened all of a sudden so no option was changed. Finally I can assure you that it isn't the drives fault, because I tried it on an other computer, and it worked perfectly, with also the correct name recognised.
