burning - CD/DVD burn error in ImgBurn and Nero

I am getting the errors shown below when I try to burn a CD/DVD on my DVD writer. I am seeing this error for every CD/DVD I try to burn. I am not able to write any CDs or DVDs using ImgBurn. The burn log below is a failed burn in Nero.

What could be causing this error?
