I have a Sony Vaio VPCL137FX Lseries all in one and my Optiarc Bd rom BC-5500H cd/dvd/bluray was working until I had to reinstall Windows 7 because of a virus. It reads cds but when I put dvds or bluray in, it loads forever then keeps popping the disc out. Thanks for any help.

Did you re-install the drivers for your Vaio model from the Sony Vaio support website after re-installing Windows?
(doesn't apply if you re-installed Windows using Factory Recovery since that process also restores the drivers).
