Black Screen of Death, WIndows ends up being dead in the water. Does anyone know what's causing this with VPS servers?

I've been trying to analyze the problem, but it's really hard. Because there's really little to analyze. Nothing in logs etc. Often even processes listening sockets, do technically work to some point. But logs do not show anything etc.

I'm personally thinking it probably could have something to do with disk I/O being slow or being so slow that writes / reads timeout etc. But I don't know. It's super hard to get anything to analyze about this problem. Maybe I'll need to write separate debug program which monitors all these aspects and reports out over socket about disk parameters etc. But what if it also dies without any sign.

Any pro-tips? I can make some poor nerdy guesses, but it's really hard to come up with proper facts backing up those guesses.

I've already placed basic monitoring which checks cpu, ram, disk read and write. So far haven't hard any of the problems. Most annoying part of all this is of course the fact, that it happens very rarely. Which makes debugging much slower and harder. Naturally the systems I'm running the extended system monitoring, haven't had any problems. (sigh)

Sometimes even the RDP works, but shows black screen for several minutes and then disconnects.
