Burning cd's

My o.s is Windows7. I have successfully burnt 3 cds of my favourite tracks
from albums I already own that I have ripped to my pc. The fourth cd is
giving me grief. It's burning to 3% then jumping to 99% and when I come to
play it on my cd player its erroring! I've checked all the settings etc and I
cant figure out why it keeps doing it?! I've tried 4 times now and running
out of disks!!!! Any advice would be greatly appreciated x
