The motherboard is a K8N Pro Sli Gigabyte motherboard. Anyways the deal is during a computer game I was playing my comp just shut off so I assumed it was the HD because I had been getting HD problems before. So when we tested HD in another comp at 1st it wouldn't boot up and then it started working if held in a certain position. Well anyways I got a new HD and still not working. Everything seems to power up but nothing comes on the monitor. No beeping sounds of any kind from the Motherboard either so I'm not sure if the motherboard is working or what. The CPU fans, case fans, cd-rom, video card fan, power supply fan are all running... is there anyway I can test to see if the Mobo works? Or is it pretty clear that its dead?
