i just got done reinstalling Windows me on my computer,
everything was fine, and then when it reboots to finish
the Windows me installing, it reboots by itself, and then
the Windows Start up menu screen comes up where i get to
choose what to do, i choose normal mode and then the
computer reboots by itself, then when the Windows me
startup screen comes comes back on i choose Safe mode, and
then the computer shuts down or it reboots itself.

where it sets up the control panel and the system
configuration, and to set up for the dardware that i have
on.
