Hello,
Hi, I have a g31m-gs r2.0 mother bord and when i put both connectors on and try it, it just flashes power on and off in a second, if i just put the 20pin power supply on i get nothing on screen? HELP would be great please. CHRIS.

I think more info is needed -- are the processor and memory modules in place, is the power supply unit to the specified wattage for this motherboad ? Are you using onboard graphics ? Is the processor fan connected to the motherboard ?
