Ok, so for the longest time I have used my Optiarc DVD RW AD-7191S (firmware Rev: 1.02) in conjunction with a program called burrrn tomake all my music cd needs. Now for some unknown reason, all the sudden, whenever I try to burn anything, either dvd or cd with burrrn, Imgburn, or any other app, I get this error list... Finished processing file #1.

The only thing I did do, is upgrade my graphics card from a Evga 8400GS to a Galaxy 9500GT. I have searched everywhere and have tried all the fixes I have come across but no luck. If anyone has anything usefull they could share, it would be greatly appriciated. Pc specs to follow....
