Hi, new user here looking to see if I can get any opinions on an ongoing problem I am having with my PC build. As the title suggests when I power on the PC all fans spin for 1 second then PSU clicks and powers off only to repeat again 1 second later.
Originally had this problem with the following, where the system worked for about 1 month before failing to post anymore:
i5-4460
Asus B85M-G
Corsair AX760i PSU
Corsair DDR3 ram 2x4gb
Samsung 850 EVO SSD
After this I did troubleshooting with 3 PSU's, 2 more ram sticks and another intel lga1150 cpu and still couldn't get a post so ended up buying a new mobo (gigabyte GA-H81M-S2V).
With this mobo the system worked for a few days before the problem resurfaced. I also switched the SSD and still no luck but no longer have access to spare ram/cpu/psu to test with.
My question would be where do I look next as its exactly the same issue as before and changing ram/cpu/psu did not get a post with the previous mobo so I'm hesitant to blame one of those this time, but also mobo seems v.unlikely as I have actually now tried 3 mobos whilst testing this problem. Have also been told that a cpu failure in this case is unlikely.
As a heads up am testing this outside the case with only cpu and ram (each stick 1 at a time or together in each slot) and 4 pin cpu/24 pin power connected and cannot get past boot loop. Have also cleared cmos and am powering via touching pins.
