I got this motherboard. I built the computer and it did not work. I tried every troubleshooting guide I could find, as well as motherboard testing guides. Nothing worked, I concluded my motherboard was dead. Today my new motherboard got here and I decided to try one last boot. I took out/put in the battery (as I have already done) and it worked. Perplexed, I did a minimal build (CPU, RAM, motherboard, PSU and sys_fan). I included sys-fan because it is under my disk drives and almost impossible to get to later. I powered it and it did not work. Only think different than my desk-boot is the sys_fan, so I unplug it and sure enough it works. What could be the cause and how do I fix it?
