My friend's PC, a Etower 366MHz always restarts when he goes to shutdown. I think it has to do with the power supply or the motherboard. Not sure though. The exact procedure is as follows when he clicks on shutdown: the screen saying win98 is shutting down... , then the one "it is now safe to..." and then instead of staying there, it beeps twice fast and reboots. Why does it do that and how can I/he fix it? Thanks.
