[SOLVED] PC won't turn on/do anything ?

[ppppcblder]

Specs: https://pcpartpicker.com/list/RdCwdD

Tugging the 24Pin VERY gently makes the motherboard do a bright white flash. Pressing the on button on my case won't do anything, still fans, still cooler, nothing moves.
Please Help.

Dont ''tug'' on anything while the power is on. Go over all your connections, un plug and reinsert all connections firmly. Try removing the gpu to see if you get power then to the motherboard.
