I have an HP Pavilion Magnesium Gray Edition p6774y PC. I am using Nero 10 to burn video files onto DVDs. During my last attempts at burning, though, my PC was making really violent grinding sounds, right when Nero 10 is burning files onto a DVD. Everything seems fine looking at what's on the PC screen, but the PC itself is raising hell! It was so loud that I had to unplug the PC to turn it off to stop all that grinding (canceling the burn in Nero was not fast enough to stop it so I unplugged the PC). When I play a DVD in the same optic drive though, it doesn't make a noise and plays the DVD fine. So, is the problem with whatever part/parts that is/are involved in the burning process? Any way to check? Any way to fix it myself? Thanks!
