I have a motherboard that starts for .5 seconds then shuts down. Through other means, I've confirmed that it is not the PSU and it is not the HSF/CPU.
I have the system set up barebones outside the case, and I've discovered something interesting and would like to know what it means regarding the circuitry.
When I short the power switch pins, it does the same thing -- turns on for .5 seconds. This is by temporarily touching the two pins. However, when I take the screwdriver and fiddle it against the pins vigorously, the computer will consistently start after about 5 seconds of this and two failed starts.
When the computer is running, it is 100% stable and will stay on for hours.
What does this mean, and is it something I could possibly fix without replacing motherboard components? Or am I stuck replacing the entire thing?
