Hi all, I recently had a problem with inserting my ram, but I got some help from the community. So I thought I would ask for assistance again. Ok here's the problem I have everything installed and plugged up and when I turn on the PC all the fans spin the gpu lights up but then after a few seconds it shuts of and shortly after that it comes back on and it stays like that. My TV can pick up that there is a signal but when I change the input there is no picture.
Here are my specs:
Core i5 -7400 LGA1151
1 stick of 8gb of G.Skill Aegis DDR4 ram
A XFX Radeon rx 480 8GB of GDDR5
A Wistern Digital 1TB hard drive
And a SeaSonic s12 2 bronze (520W)

The fans are just the stock ones were mounted in the case.

Here is a video to show you what's going on.

took out the gpu tried it didn't work. Switched the ram over to the other port, no dice. I'm just going to take the mobo out and redo the build. I feel that would be the best way to check everything.
