Can only burn 9/10audio songs, rest corrupted

os win98se, 1.3 processor, 256k ram
atapi cdr 48x12

nero 5.5

when i burn, i usually get 9 songs perfect, and cd track corrupts and hangs up on song 10. songs after #10 or 11 have problems. Nero says burn successful, though

tried playing cd’s in another medium, same things happen.

have tried burning at lower speeds, but do not know how to correlate cdr medium size and the speed.

have closed everything that is open, as well as screensaver, and disconnect auto-insert notification.

thanks in advance.
