My computer was running perfectly fine (built in February 2014) and ever since I turned my computer off at the PSU switch it hasn't turned on again (no fans, lights, or noise from the pc).

I needed to turn the computer off at the PSU because it went into deadlock, and I tried holding the power button for 5 second but it didn't turn off at all.
I originally thought the problem was the PSU, but after testing a new PSU, with my system it still has the same outcome as before.

Is the problem to do with my motherboard?
Is it possible that the other components in my system could be harmed?

Original System (before the problem):

New PSU:

Things I have already tried with no success:


I have tried reconnecting all the parts except the CPU and still nothing.

The motherboard is mounted on all standoffs in the case, leaving no standoff touching the motherboard on the back.

I have now tried both sticks of RAM separately and still nothing.

I have now tried booting the PC with only the CPU, motherboard, PSU and one stick of RAM, but still nothing..

I have also reset the CMOS and still nothing

The power outlet is working fine.
