Try removing the IDE controllers in device manager and reboot.

is it safe to uninstall ide controllers from device manager???

there are 3 in there?
primary ide channel
secondry ide channel
via bus master ide controller

Yes it’s safe. Windows will re-install ide drivers on reboot.

shall i delete all 3 then?

Yes, but it’s only necessary to delete the primary and secondary IDE controllers.

sorted now :smiley:

thank you

No problem. You’re welcome.
Be sure to go back into device manager and set DMA on.
And Enable CD Digital Audio.
