Help: Overclocking - Affect DVD Burning?

I am using a brand new Samsung 184M USB DVD burner. Before I overclock my PC, I am able to burn DVD. Now, I couldn’t even burn a single DVD, all end up with Write Failed. There is not much info given by Nero 7 premium.

I also notice the DVD drive does not perform at its maximum speed. I have MagicSpeed and InCD running.

Do you think OC cause all these ?

It can, yes!
