Perhaps you could borrow a burner from a friend, build it into your PC and try to burn CDs with that one, that way you can rule out it's the burner that's causing you trouble.
For a system profile, my gues would be a DxDiag dump, to get this:
Start -> run -> "DxDiag"
It'll open a new window with all your systemspecs in it, you can find a button there that saves all the information in a .txt
Good luck,

Oh and BTW: Technically speaking, a Vinyl record holds more sound quality then a CD/DVD cause it stores the information analog (in Sinusses, not in diggets)... but I understand what you mean...
