Hello there,

 

I just bought a new gaming computer and it is having a few issue's.  It turns off for a few seconds right at startup, then turns on again.  I have troubleshooted this issue for a while.  I have come to the point where there is nothing plugged in to the system except the mother board, the power supply and the power switch.  I am not sure what to do at this point.  Do I Get a new Power Supply, a new power switch or a new mother board.  If anyone has any suggestions that would be great.  Oh yea.  The entire time this is happening nothing will be displayed on a monitor.  

 

Thanks,

Dustin Moss

Unfortunately, either PSU or mainboard could be at fault, assuming there are no shorts underneath the mainboard pertaining to mainboard standoffs, spilled conductive thermal compound, bent MB pins, etc..) .. (However, a power switch is very unlikly, as it merely shorts two pins on the mainboard momentarily to tell the mainboard to apply power)

 

Certainly, putting in a known good PSU is easiest, and, usually least expensive...

 

(you must have one functional stick of RAM installed in the required slot, of course)

It absolutely is NOT the power switch. As you can see from this tutorial ... 

 

 

... you don't even technically need the power button at all!
