First off, my knowledge is limited (read "relative newbie")
but I have twice experienced similar situations that you are in.

The first time it was mem, but you already checked that.  
Maybe you could test the HD?  When I was having problems it
would just get to a certain point and lock up.  When I tried formatting
it (via DOS) it would also lock up.  Popped in a new HD and my
problems disappeared.

Hope it helps.
