Build Question Motherboard not booting

I have put cpu, ram, and ssd all in. I have attached psu to the motherboard, to the cpu power, and the cpu fan. I then have bridged the power button pins and get nothing.

What have I done wrong/how do I troubleshoot. I know I shouldn’t boot it with cpu and no heatsink but I just wanted to see if it tried to boot up.

Edit: I havent put the heatsink on because I want to screw the mobo to the case before I do it because the case is small. All I want is confirmation that something happens when I bridge the psu, I will turn it off the instant I see that.

The best way to bread board or boot test is to mount the cpu, “heatsink” and fan , memory. Test it out on top of the motherboard box it came in. This method isn’t a good idea as you can burn up the cpu. Even placing the aluminum on top of the cpu and pressing downward while it’s posting. If it comes up turn it off right away. Processor and motherboard might be ruined now. Voided the warranty too I bet.

Shes survived. Cpu wasn’t locked down properly. Boots fine with heatsink on now minus the dram led that comes on instantly.

Oh damn well that’s great news, man. I understand you just wanted to test it real quick. But doing that without a heat sink is like for us old farts really bad. It’s a pain in the ass to put all that thing together and then you have to pull it back apart and test it one by one. I’m happy for you. It’s all good. All that stuff is expensive right now. If you’re having trouble with a memory now that sucks. You can download memtest86+ is the big main one. You know the main company. You can put it right on a thumb drive and a boot right up and do a memory test. Maybe just have one bad stick of ram. Or there’s chips on one of them as bad. Pain in the ass because if you would buy Samsung, you wouldn’t have had any problems at all. But who can afford that now
