I moved everything from one case to another.
Got "no signal" on screen (from graphics card and motherboard)
Bought new motherboard, same problem
Tried removing one and the other RAM stick
Tried using a different psu
Checked all the cabled many times
Read all the manuals
Cpu is working (gets hot when turned on for 3 sec without fan)
Tried 2 different cpu fans
The pc "starts", the fans spin, i can charge stuff in the usb, eject the dvd
No beeping sound (have no speaker on the pc, should I plug that in?)
And I have tried 3 different screens, vga, dvi, hdmi
One really important thing I did wrong was not to place the chopper standoffs in the new case with the new motherboard (have done that now still have the same problem). Could That brake it?
I didnt put the standoffs in when I moved the old motherboard over to the new case.
Could I have broken both?
All the parts worked in the old case
Thank you all

I think you may have damaged your motherboard by shorting parts out.
Take the motherboard out of the case and put in on a piece of cardboard.
Then connect the minimum number of parts and see if it starts.
You can use a flat blade screwdriver to touch the two pwr switch pins if you do not have a pwr button on the motherboard to start it.
If it fails, replace the motherboard. If it is still under warranty, see if you can rma it.
