Hey guys, first time posting and I hope you can help me out.

So, I have my buddies rig ready to go but I am running into an issue. Everything is plugged in and ready to go, but when we power on the computer the lights and fans will turn on for about a second and then turn off. About 2-3 seconds later, the same cycle starts again where all the lights turn on and then go off again. I’ve tried 3 different powersupplies so I am not sure what else it can be. I’ve even taken out the GPU to go to as little power as possible. It’s only an i3 so I know it isn’t a power hungry processor. What could it be? My only goal is to just get the damn motherboard to get sufficient power to stay on which isn’t happening.

I’ve tried resetting the cmos, booting with only 1 ram stick, and even taking the mobo out of the case in case anything was being shorted. Here is a video of what is happening:

My only either guess, besides a DoA board, is the case is kind of old and beat up and possibly the leads from the power switch are faulty. Is that possible?

Board is a gigabyte GA-H55M-S2H.

Thanks!

Welcome, It sounds like the Motherboard is going out. If it is not a power supply then the Motherboard is the problem..

Hi,

If you think the power switch leads are faulty, I have read that you can jump start a computer using a screw driver. Unplug the power switch from the motherboard, then touch the 2 pins on the motherboard where the switch was plugged in with the flat head of the screw driver. This makes a connection between the 2 pins and hopefully will start the computer! :open_mouth:

Just watched the video and it looks like the motherboard is bad or going bad, How old is the Motherboard ?
