    Hi.
    I've been building and servicing PCs since 1985. Just offhand, I would guess that your PSU has died (though it could be that you did not fully insert the 24 pin power connector).

    Dell uses proprietary stuff, so you have to be careful to be sure that something you will try is in fact compatible. Since I do not have experience with the XPS 400, I leave that to you.

    If you are in the USA, you might want to look at Dell business computers which are coming off lease. Something like a Dell Optiplex 7010 or 9010 might suit you. Can be found for less that $100-$120
