Hi, I'm having trouble booting my computer. It's an old comp intel pentium 4 processor 3.0 ghz socket 775 and its mother board is Gigabyte GA-8IP775-G. I put in a new 500 gb SATA hard drive and whenever I boot it up I get to the Ubuntu Lynux install page and my computer just shuts down. I was running the power supply through my very old computer and it worked fine. The power supply is 350 Watt. Also there is 4 gb ram dual channel. Thank you to whoever posts.
