On his avatar is Bill Hicks which also died in ~33 years. From a cancer.
On his profile picture is a man going to a light by a corridor, what associates with known short "death" dreams.
Probably he had a disease and suspected to live not long.
I'm sure Raver would have mentioned it to someone had he known. And I for one was never given a hint that anything was amiss with his health.
As Nairda pointed out, based on what information could be found, a brain aneurysm seems most likely.
Over here, we'll put up with (almost) all of your crap. You just have to use the secret phrase: "I don't value it. It's related to <insert random element here>, which is not in my quadra."
