HP DVD840 does not recognize DVD discs



My HP DVD840 suddenly stopped recognizing any DVD discs. It will read any type of data or audio CD. DVD discs bring up “no disc found”. What might be causing this?
Windows XP Pro SP2 on a Pentium 4 desktop.



Could be a dead DVD laser-diode. Try booting from a bootable DVD (Vista, Linux,…). If that still works, uninstall any virtual drive software (Daemon Tools, Alcohol,…).


im having a similar problem. all of the sudden one day it stoped reading DVDs movies
now it wont read audio disks
the only disks it will read so far i know are game disks and normal cds
any thoughts?
