Well, if the keyboard/cursor freezes on screen, that probably rules out the video cable. There might be something loose in it, so, if it was me, I would open it up and check all cable connections, specially the hard drive which will cause the machine to lock up if it is suddenly unplugged. If all connections are good and it still exhibits the same problems, then you're probably looking at another motherboard... -Laurent. -- ============================================================================ Laurent Daudelin AIM/iChat: LaurentDaudelin <http://nemesys.dyndns.org> Logiciels Nemesys Software mailto:[EMAIL PROTECTED] fudge: 1. vt.
