a few days ago i was using my computer when there was a powercut. When the electricity came back on i turned the pc on the drive stopped working , the light doesn't flash nad it wont open. Its a sony 16x dual layer drive.
Yes thats them, any of them will do I'm just trying to work out whether the power supply is damaged or whether the DVD is damaged. If it works with another connector then you know the old connector is faulty, if it doesn't then try connecting the hard drive one to the DVD and any of the others to the hard drive and see what happens. If windows still starts ok after this and the DVD still isn't recognised then it looks like the DVD is damaged and will need replaced though there are a couple of other things you can try before confirming this.
