First pc build and it won’t power on

I took out one of the fans cuz I saw a video saying you can jumpstart the motherboard with a screwdriver when the power buttons not working but that didn’t work neither did the little power button on the mono. CPU is 9800x3d 240mm aio with fresh thermal paste tried plugging into the wall and power strip neither did anything
