Booting up my Motherboard outside of case.


Mar 7, 2010
I purchased an evga-h55v motherboard and a i3-530 CPU. When I short the jumpers for the power button (only for 1 sec or so)the fans start spinning for approximately 2 seconds and then go off for 5 seconds. Then the cycle repeats over and over. I have a good reason to beleive that my MB, CPU, RAM and PSU are all ok. I saw a tech at Tiger direct boot up my board but unfortunately don't know what he did different since I assumed it was a PSU prob at the time. After buying a new PSU that night I tried to recreate the same barebones hookup as the tech guy had (MB out of the case and PSU with Monitor, Mouse and Keyboard all hooked up) I ended up having the same symptoms as before. What am I doing wrong or what did I miss that the tech did to make it boot up. Thanks in advance.
