Just finished system - started fine then lost power

[Papadrom]

Built the system, ran for 5 minutes while I looked around the CMOS - inexplicably shut down, and now it won't turn back on...

Is my power supply not strong enough?!

the CMOS reset light on the back is lit.. so its getting some power...

I discovered two LEDs blinking on the motherboard right next to the RAM DIMM - a yellow and green one on top of each other... I can't seem to find what that means even on the products website- I emailed GIGABYTE for support - hopefully they will help me soon.

Your manual:

Page 22-23 may help with the meaning of the LEDs. Would love to help more, but unfortunately all of the LEDs are "right next to the RAM DIMM".

Ha! I know. I read the manual and it seems to circle the same set of leds 3 times...

I started unpluging things and striping out components... testing along the way... it still does the same thing even by it self.. so I guess its either the mobo or the PSU... based on reviews - its probably the Mobo so I guess I'll RMA it.

Are you sure the processor fan is mounted correctly? If the fan isn't on just right it can cause your computer to shut down in less than a minute.

99 % certain. This isn't my first time building a machine and the way that it went down just seems unusual ... secondly - it won't even attempt to turn back on again... the motherboard seems to be denying the ability to turn on the computer. I really really hope I can get somebody on tech support tomorrow and get this resolved.

I'll post a complete report on my original build - problems I encountered, and what I ended up with.

Thanks!
