Optiarc AD 7191S Issues...

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...

I have not upgraded or downgraded any apps, reg files or drivers. 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....
