with respect , its a catch 22 situation.
follow this thread from beginning >>

notice your stats in reaper. underneath the X. ??
what its telling you is big latency.
thus problems.
the only solution if you dont want to buy a proper interface
is to install the free asio 4 all driver, and see if that helps with on board sound. then see what reaps reports under the X for latency.
there is lots of info on the net in setting up a pc for studio work. eg gearslutz.com and you tube.
