Broken CPU Fan header preventing POST?

Rik1254 · 10 Nov 2015 at 22:42

I've been having some issues with my motherboard lately and I've seemed to have tracked it down to my CPU fan header.
Nothing will work on that header (all other headers spin the fans/ water pump), but I don't have a multimeter to test for current.

Originally I thought I cooked the CPU, but that works in another unit fine, same with GPU and RAM. I've tried a complete barebones 1 stick and iGPU and still no POST.

The board has debug LED's, but it says it's ok (no fan or heat errors).

I did have some problems when I reset the computer, it took around 130 seconds from clicking restart back to windows on a Samsung 830 SSD. Maybe it's related?

Anyone have any ideas?

Have you tried disabling rpm monitoring for that header in the bios?

I get no display at all, so I can't even get to BIOS

what board the z77 in sig?
if so try,
imple Plug & Press - Hardware-based BIOS Flashback
A truly revolutionary hardware-based update solution. USB BIOS Flashback offers the most convenient way ever to update the BIOS! It allows users to update new UEFI BIOS versions even without hardware such as a CPU or DRAM installed into the motherboard. Just plug in a USB flash drive containing the BIOS file, and press the BIOS Flashback button for 3 seconds with the power supply connected. The UEFI BIOS will then automatically update without requiring further interaction.
