I have updated my firmware and all that. I would go and say that the discs i got a rubbish but i have burnt with this brand before and they worked, but saying that, the ones i used before were blue, these ones are yellow. but they are exactly the same as far as i can see. i did install a new power supply for my comp a few weeks ago and this is the first time ive tried to burn after doing that i cant see this affecting it.

I will go buy some verbatim discs see if they work.

Any help would be greatly appreciated ty
