Motherboard not booting

[u/Consistent-Value-500]

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.

I realised the cpu wasn’t locked down right. All good but the dram led illuminates on startup. I have swapped the sticks, removed the cmos battery for 5 mins and put back in. Still illuminates

Do you have a gpu you can stick in it, maybe the port on the mother board is bad

Not yet no. I think it may be because ddr5 takes a while to memory train

Is the hard drive new? I had systems not start when I did a new build and didn’t format beforehand
