Welcome to the forum.
What are your PC specs - processor & memory & hard drives (size and rpm)?
Too little memory and/or slow hard drives may add to the suffering caused by the onboard soundchip.
Integrated soundchips usually don't understand ASIO drivers. You could try ASIO4ALL (download). It's a band aid for cards which don't use ASIO.
The drivers come free with the soundcards, you can't buy drivers, and if you could, they're no good without the soundcard they're made for..
A dropout simply means your soundcard/PC are not fast enough to do the job.
You could try increasing the buffers sizes in the Options-dialogue, but I doubt it helps much.
You'll not be able to do fluent DAW work using the onboard soundchip, unfortunately. You can manage, possibly, with more or less glitches, depending on you PC specs, but it won't be easy.
