Seemingly no motherboard output after changing case

Hi all,

I am having an issue with my custom rig and would really appreciate any tips.

I bought the NZXT phantom full tower (as my old case was literally decaying) moved all the components across and when I turn it on all of the fans start up, LEDs turn on, CPU fan is on, motherboard lights are on.....but no output to monitor and my mouse does not light up.

Something is stopping output from the motherboard, and I have absolutely no idea what it is. Everything worked before moving it across.

I used the standoffs in the right place.

I also benchbuilt it with bare bones, same problem. I also used another motherboard (thinking the mobo mightve been damaged somehow whilst moving it across) but same problem.

Any ideas?

I don't think so. I don't hear any beeps, and there is no output to monitor.

The lights on the motherboard turn on when the PSU is switched on, and then once the machine is turned on via the case power button, the fans/LEDs/cpu fan all turn on. Simply no output to mouse/monitor.

I tried that when I benchbuilt it and unfortunately the same outcome every time :/

Everything seems to be pointing towards the cpu as the problem (as this is the only component I can't swap for another to check), but I can't see how the cpu is knackered just from moving into a new case - everything was working fine until I swapped it over.

I did, and took care with the other motherboard too.

It's a really odd situation- I really hope it isn't the cpu, but I just can't seem to figure it out! I took it to a pc repair shop and they couldn't find a solution.

They guessed at cpu but they didn't have equipment to test the it, nor did they have a spare to check if that worked.

I re-sat the cpu and unfortunately no luck. I think I'm going to have to take it somewhere where they can test each component and put a a different cpu in.

I really don't want to buy a new i7....
