Go to control panel,click on system,advanced tab startup
and recovery section click settings,system failure
uncheck "automatically restart".This will keep computer
from restarting and hopefully give you some sort of
message of what is wrong.Also as allready posted,go to
event viewer and see if any errors are listed
there...Good luck.
