I recently got a motherboard somebody gave to me and am trying to build a new computer with it. The motherboard is an els elitegroup 755-a2 ver. 1.0a. It has an AMD Athalon +3000 processor 64. I just bought 2Gb of RAM, a Hitachi 500Gb sata deskstar hard drive, an LG internal/GH22 super multi DVD writer, and a nvidia geforce 7300 gt. I have everything hooked up and it acknowledges that I have them hooked up, but i can't access bios and it doesn't go past the the first boot screen. What am I doing wrong?
