Well actually, the Hive Mind was not asleep during the Great Crusade/HH era, there are hints in some of the Tyranid Codexes, and Horus Heresy Novels that atleast Genestealers were in the galaxy at the time, so the Hive Mind would have been directing them in some way possibly having them scout out the new galaxy. But I think the Chaos Gods will struggle against the Tyranids due to the Shadow in the Warp, and now that the Emperor could basically be considered a Warp-Entity at this point, he would be weaker than he was before being placed on the Golden Throne.

The C'tan are actually the oldest race in the 40k universe, considering that they were formed at the beginning of the universe, but it's a close tie between the Old Ones and Tyranids, but no one knows exactly how long the Tyranids have existed, and it's likely that they are just as ancient as the Old Ones, but defenantly not older than.
