OK, now we're talking real facts with the PC specs.

You don't even have a "harddrive" as in the post title. You have a solid state drive. This is great, the best thing about that PC by far! I suspect the problem lies elsewhere.

The Geekbench single-core score will reveal if the Atom CPU is adequate for BIAB.

In the meantime, go into Options, Preferences, Realtracks and find several checkboxes related to "slow PCs" and make those adjustments.

Did it come with a whole bunch of software preloaded? Blowing that away might help a lot.
