Weird things needs something explanation

[Advanced Vending Machine]

hi i need some help for my pc

i just got new case but weird things started happening when moving in it, the case is Core X5 from thermaltake and the old case is HAF912 Advanced from cooler master

 

now to the issue, power on fan spinning led on cable double checked but no signl on the monitor, i tried many solution but nothing worked and from here nothing make sense, i moved everything back from the Core X5 To the HAF912 and well........ there is a signal there is the Bios..... moving back to the Core X5........ No signal......... i don't know what to do

Everything fully seated? All standoffs installed? That is odd.

before there were some stands that weren't attached correctly(loosened) and i replaced them twice and removed the extra(6 standoff in the case)

i will try to move the standoff from the old case to the new one and i will post if everything is working

still not working

edit: i will take it to someone who can diagnose the problem

it's Alive! finally

the problem seemed quite stupid, the case places the motherboard horizontal and it seems the problem was the ram it was not installed correctly the backside of the ram didn't look big or angled but i tried to push it down and it clicked....... literally clicked not when first insert it just click and then i tried on the other one and it worked the pc started like normal

 

conclusion: i need an eyesight test
