    That's what I meant. My drive turns slower - should require less juice.

    That's all the specs give - it's startup requirement. They give the
    normal operation (max load, idle, ens) only in watts.

    Mmmm, the thing is, the resetting happened mostly while I was not using
    the computer no load, no CD-ROMS working, ect. And it tended to stay up
    for a couple of hours before resetting.

    That's what I think happened. Or rather, it got too hot, and did the
    same. As it gets hotter, resistance increases so it has to work
    harder. Comes to the same thing.

    He he, I see that all the time!

    Thanks again for the replies. Everything is fine now, the culprit was
    definitely the fan - fixing it eliminated the problem... But it's
    always fun to find out the details and reasons behind the problem

    Kind regards
