Big problems

Well my computer is 600mhz and 256ram and it always worked from backuping from the HD until i installed windows xp and it appears to give me almost everytime i try to burn several different errors each time it varies for instance i almost everytime get buffer underrun or something with “sense” and track error each program it changes i have tried several ones now and with iso’s it seems to work pretty decent

my Cd writer is HP 8100

but it’s not really the issue here the thing is i ordered NEC 1300A apparently its the oem version

and i am going to get it next week now i dont wanna be stuck with all these problems all the time

do you have any suggestions people?
