Dell Inspiron 4000 Motherboard.
I replaced the motherbord because the plug for the power supply broke off. It was given to me by a friend and it looks as if someone else worked on it. Anyway... I replaced the motherboard and the keyboard.
Like I said. It sounds like it starts up and then goes off after about 3 seconds. Every once in a while I'll get a white screen, other than that I get nothing on the screen. I can't hit the setup key to go into BIOS. Dell's website says when you replace the motherboard you have to update the BIOS. I don't have floppy drive on this computer to do that, but I do have the update program. The computer is plugged in and the battery is charging.
thanks for you help!
