Ok, so today I recieved a Poweredge 1800, with 6 sticks of RAM, a 3Ghz Intel CPU, and 2 hard drives. I plug the power lead in and 1 of the fans start up (out of 3), I then press the power button and it boots up, taking a while as it is still a server machine. I install a dynamode PCI lan software on it, and select shut down. It was taking a while to shut down so I did it manually by keeping the button pressed in. I now put the card into the right slot and plug the power back in, yet again the fan comes on, but this time when I press the power; nothing. I have tried disconnectiong various things, and reconnecting them, but still nothing. I just get a green light on the front, and a continous flashing light which is either orange or blue (the light changes colour when i press a button named NMI, I don't seem to know why it wont power up fully and boot. Can anyone please help? Thanks.
