no power, led light on motherboard flickers after 15 seconds

[jayreed21]

Hey guys,
I am working on a buddies system and he cant get any power. First off he had a deer power supply. Second he replaced the motherboard and didnt have all of the studs screwed into the screw hioles of the motherboard. So i took out the motherboard and set it on an electrostatic safe bag and plugged up a new agi 300w power supply and the led light on the motherboard will come on for about 15 seconds and then start flickering. Does this indicate a bad motherboard? With the deer power supply the light only stayed on for like 5 seconds and would flicker on and off. The mb is an Asus a7n8x-x.

Is this a brand new build?

Don't put the motherboard on a anti-static bag...it conducts electricity and you're shorting out the motherboard. Put it on a non-conductive surface.

Try powering up the motherboard with no RAM or no video card installed. Make sure the PC case speaker is connected if that motherboard doesn't have a on-board speaker. When you power up the system, you should get BIOS beeps indicating a problem with the video card or RAM. If you don't get a response, the motherboard may be bad.

bad move...might have ruined it doing that.

try resetting the bios and plug up a good psu to the mobo with it out of the case, sitting on something non-conductive. test it with a different video card and different ram if you can.
