I have tested components by unplugging everything from the MoBo and then plugging one by one. Currently the issue seems to be the PSU, MoBo or CPU. The pc powers on fine when the CPU is unplugged from the PSU (4pin). Once the CPU is plugged in and i power it on, after a second or 2 it powers down and powers back up.
I thought it might be a short between the MoBo and case so i detached the MoBo and put it on a plastic box so there was no current possible between MoBo and any metal.
Tried connecting the green and black wire on the 24 pin connector with a paperclip and turning the PSU on and that made the fans light up and stay on, so the PSU is at least not totally dead.
Took out the CMOS batt. but no change, tried the reset button, no change, tried grounding the MoBo to something metal with a paperclip, no change.
Plugged a monitor into the motherboard directly to see if the BIOS is opening at all but no response.
Besides the named components only the fans, power button and reset button of the case are connected.
PSU is 500W EVGA
MoBo is GigaByte GA-H1100M-H
CPU is Intel Core i5 7600K - 3.8 GHz
