Hi,

 

 I have ALL external connections (except power and monitor), HD and memory disconnected. Power on comes up blank monitor screen, no beeps , amber power light, blinking 234. During power on, fan starts slowly and within 2 or so seconds on full blast and it stays that way. Power supply has green light. ram battery is good (3.3V). Looking for thoughts. Motherboard LED is on.

Thanks

Tom
