Well, short of extreme measures such as X-raying the computer, you'll have
to find out by running some sort of program. To do that, you should either
say what operating system is currently running on the computer, or run
some sort of live CD. The latter has already been mentioned as a possibility.

So, at this point, why are you still asking questions?
