I got myself a new CPU, Mobo and ram and after installing it and when I turn it on, it goes on for a split second then shuts down, it does the same things when I let go of the power button aswell.

I have tested the gpu, ram and HDD and those don't seem to be the problem. It isn't a standoff short circuit either The only time it would stay on if I unplugged the CPU connector which then the whole system would stay powered on.

Specs:
G4560
biostar H110MHC
1x8gb Samsung ddr4
550w gigabyte power supply

Any suggestions help

You probably got it up and running, i'll answer anyway.
This seems like a CPU problem, is your CPU fan properly connected and does it run at startup?
-Check all cpu-pins.
Still not working?
-Try unconect all cables. hdd, dvd, fans etc. exept cpu-fan and monitor.
-Try start with different RAM piece.
-Unmount GPU and use motherboard display outout.

Now you got either a faulty motherbord, CPU or PSU.
Is it running?
Try connect one cable at a time to find you're problem

Thanks for the reply but I already found out that my psu CPU connector wasn't working properly which is odd since it worked with my old Mobo so now I'm stuck with a PSU that doesn't seem to work with my mobo
