posting issue Motherboard will not POST

[erockio]

I am desperate for some help at the moment. I bought a new motherboard to replace my old one since it was getting a bit dated. The new board will not post, no matter what I do. I will get fan spin, LEDs, GPU power, it will pass the memory check and then the diagnostic light for the CPU will stay red forever, I have let it sit and churn for a while hoping it would post but no luck. Here is the real kicker, I know the board works because it posted multiple times for some unknown reason after I shorted the reset pins a couple random times with a screwdriver, and then I rebuilt the rest of the system thinking it was good but it wouldn't post again after.

 

Troubleshooting I have done:

-Swapped PSU

- swapped memory, tested each stick in every slot

-tested the cpu in another board, works perfectly

-tested my memory with another board, work perfectly

-unplugged everything non essential and it still wouldn't work.

-reset CMOS

-removed CMOS battery 

-tried varying degrees of pressure on the CPU from my aio cooler

-unplugged board and CMOS and let sit for hours

-checked for ram comparability with my board, should work just fine.

-bought a secondary CPU eps cable to power the four pin power slot besides the 8 pin which should be plenty on its own in theory
