No post, no lights butt remains powerd on

[Caazje]

So i got my new i5 4690k in the mail, and when i went upstairs my pc was showing a black screen. while powered on.

So i rebooted it and still nothing, no post and no lights on my mouse and keyboard.

I replaced my 4430 for the new i5 4690K and still nothing. 

I tried the old cpu, without the gpu, with one stick of ram. i got a post, second stick of ram, that worked.

I put the gpu in it worked. i completly assembled it, and no post no lights....

So now i don't know what to do.

For some reason it isn't stable anymore, what are my options?

 

All the specs:

Msi z87m-G43 Bios v2.9

i5 4430

R9 390

16GB 1600MHZ DDR3

RM750i

Take the whole system out and build it on a test bench (cardboard box will do)  plug in all the components (but dont use the i5 keep that safe until we know what's going on) 

 

You're most likely installing a bad device be it led stip hard drive/ssd or one of the 10`s of other parts 

 

let me know what happens when you build the test bench

I tried it with 1 stick of RAM and no GPU and the 4430. It booted.

Put the other parts in one by one and see what makes it not post

i tried the second stick of ram in slot 3, no post. in slot 2, post.

i also got a post with the gpu...

So with all the parts back in place it seems to be working again.
