The usual recommendation for a first test is to see whether there is
any network activity e.g. response to ping or ssh. Also try Ctrl-Alt-F3
to see if a console is reachable as X might have problems.
Have you checked logs to see whether there is anything suspicious
before the freeze? If there isn't, the odds are in favour of a hardware
failure.
If that looks to be the case, I'd open up the machine (assuming it's
not under warranty, if it is, it's someone else's problem) and reseat
all the movable connectors and RAM. There's less chance of contact
problems with SATA than with the big old PATA connectors, but it's not
impossible. 'Fairly new' it may be, but connectors which aren't locked
can be jarred half-way out by transport. We can probably rule out a
build-up of dust yet, but if the machine is very quiet, and modern
machines tend to be, the fan might have died. There will be a lot more
troubleshooting tips around the Net.
