Sony DVD-RW DRU190A not working

Certain cds and all the dvds are not working in
my Sony DVD-RW: DRU190A. Only certain cds are
working and not all the cds. All this happened
2 days before and everything was working before
that. I had finished uninstalling and
reinstalling drivers, done firmware update,
also finished running sfc /scannow. I had
unplugged and replugged the cables and also
finished auto updating. Restarted the shell
hardware detection in Services.msc. No use. Can
anyone suggest me any other troubleshooting to
make the dvd rw to work properly?
