Got a problem I'm not sure about. Building a system here and when I shut it down it won't start up again untill I pull the power cord and plug it back in. I'm thinking this is a Power supply problem. It is an older case and it is only a 200 watt power supply and I'm putting it on a PIII. This could also be a mainboard problem. Help me decide. Have a new case coming anyhow. Also noticing that the CDrom isn't opening all the time. That could be the cdrom. It tries but won't.
