Hp 16x speed is SLOW?

hey fellas… so lately my hewlitt packard cd 16r (16x) cd writer is going SLOW!!! i have no idea why… i’m still using nero as always, and it’s taking 13 minutes to burn a full cd (used to take 4 1/2)… i’ve tried running ad aware to make sure the’res no spy ware, i’ve also tried feurio and a couple other programs and it’s still just as slow…

i have xp runnin on an msi k7d motherboard and dual 1.6ghz processors with 768mb ddr ram…

any one have ANY idea what the problem is? i’m totally stuck on this and it’s infuriating me!

please help!
thanks a lot guys
