This is the first time that I've setup a computer from scratch. I am using a D510mo, 2x2GB RAM, with a 350W power supply.
The intent is to set up Ubuntu from a Flash drive. I am having initial troubles with the motherboard as it will power on for a second or two (fan on power supply spins), then powers down (small LED on motherboard is still lit). I put a jumper on the on/off front panel connector pins.
Are there any other essentials that I am missing for the introductory part of setting up the computer?
