computer constantly reboots

Everytime i dial up to the internet the computer 4 no apparent reason reboots
and disconnects i am using a 56k modem windows xp and i have recently
downloaded sp2. The error report says that we have not installed the
necessary updates but when i attemt to do this it just says that i have all
the updates that my computer needs. It also has happened once the connection
has been established maybe 1/2 hour into connection.
Can someone please offer some assistance.

I would suggest you try:

Do a virus and a spyware scan ( ad-aware, spybots)

in control panel\system\advaced\startup\setting uncheck auto restart
look in administrative tools\event viewer for possible error.



for the updates questions try these:
