you're hardware definately needs beefing up a little....but nevertheless, you should still be able to make cd backups without too much hassle.
considering your hardware spec, does your cd-r/w have buffer-underrun protection?

I see you're trying to backup PS2 games, if the games you're trying to backup are DVD's, you'll struggle to make an image with only 1gb of space available as the majority of games exceed this capacity.

you should always make an image first, then burn this back to cd afterwards. 'On the fly' can be risky at best...
