(bold represents upgrade)

 

I’m doing a massive upgrade, and now whenever i connect the build to power (not even turning it on), it flickers for a split second and then goes dead, the on button doesn’t work.

things i’ve done to try and fix it:

-reset mobo battery, no response

-swapped around ram, one at a time, each slot, no response

-checked my front header connections, shorted front header power pins with screwdriver, no response

-made sure my gpu was in properly

-checked if my psu was working, by doing the corsair method and then putting all my old parts back, still worked

 

and no, i didn’t assemble this on carpet, i did it on a wooden table, and in the video its on a thick plastic sheet

 

so is the mobo bricked or what?

Remove GPU and see if you get any beeps if not then go below. 

Try to re-seat the CPU again and see if that works.

 I had a mobo, with a CPU combo and it refused to boot until I re-seated the CPU again.
