I have researched the forum, but did not find a specific answer to my query. I just built a new computer from scratch. This is not the first one, but this one is giving me fits since I have never has this happen before. After installing all of the cards, peripherals, etc., I powered on the system. It booted to the CMOS and Bios, but shut down after about 5-10 seconds. I thought it may have been a conflict with one of my add-on perepherals, so I un-installed them one at a time, hoping this was the culprit. However, I am still getting the same problem. I am at work now and I will do more troubleshooting when I get home tonight, but I am seeking assistance. One thing that dawned on me while thinking about it here at work is I may have one of the cable wires from the computer case disoriented on the mother board. I'll check that when I get home. Anyone have this problem before?
