Broken CD Burner?

Ok I have no idea what is wrong with my cd burner. i am using nero. i have tried many options to fix the problem but on nero it never passes 3% and other burning software also dident work so there is something wrong with my burner I know that but how would I fix it?

u KNOW u need to give more info than that about ur system config and the nature of ur error. Let’s try that one again

What are you burning? Speed? Media? Burner? Hardware Config?
