I have a motherboard that stopped working recently, and for some reason I thought it would work if i try it now after a week or so of it not working. I put it into the case and plugged everything. Connected it to my monitor and the PSU fan and CPU fan start turning, but after a few seconds everything just shuts off. The power supply is the EVGA 600W (yep it's just called that). I used to use it in my old gaming pc and when i accidentally pulled the power plug a few times it makes a noise when the power shuts off. The power supply makes the same noise after a few seconds. Is the motherboard still dead or is there something I can do to get it to stay on?
