I have a similar problem to the last guy.? I have a brand new gigabyte 3d1 MB.? You know the one with the dual gpu video card.? Well I put it together last night and made it into to the bios and turned off the integrated audio and whatnot and then went to bed.? Today when I went to turn it on the LEDS on the front turned on and then turned off.? All fans spin up and all lights turn on for a second and then turn back off again.? If I press the power button repeatedly it seems that the system runs normally but I didn't boot like that in case it was a CPU overheating measure.? I took out all cards and disonected everything.? I even pulled over another old case and used the power switch from that with the same effect.? The LEDS on both sticks of ram turn on and I tried clearing the CMOS and taking out the battery for 10 minutes with no power to the MB.? I'm at a loss.? Is it my MB, CPU, or PSU thats causing this?? Any help is greatly appreciated.

Hi Tim

Have you checked to see that there isn't a short on your motherboard - i.e: the motherboard is making contact with the case at a particular point?

I shook it to check for loose screws behind it but i'll look again. Thanks

Did you also move a jumper around when clearing the cmos?
If youre mobo has a jumper for that anyway ,have a Look in youre manual if you do have one ,and for exact instuctions for youre mobo ,it probebly looks something like this:

Thanks for the help. I picked myself up an Antec 430 watt PSU today and installed it. My computer booted up just fine. I guess 350 watts of generic weren't enough.

Great stuff! Well done, your PC deserves it
