I started with an overheating CPU. It would boot to the bios, quickly heat up, and shut off. I checked the AIO speed in the bios and it said N/A. I was able to get to the bios and update it. It crashed once during the update but I was able to install an updated bios. I still had the overheating problem but was able to boot into the bios. I figured I had a bad pump for the cooler.

Got a new cooler (CORSAIR) and installed it. Now the motherboard has a solid yellow light and will not boot to bios. Before, the lights would cycle and I would get into the bios.

When it was in the case:

I have tried only using one stick of RAM in multiple slots.

I have tried resetting the CMOS without the battery.

Without the hard drive.

Out of the case:

I decided to take the MOBO out of the case and completely start all over (reseated CPU, all cables, RAM, etc) Still stops on the yellow light .

No video card.

I have also tried to flash the bios with the button on the back of the motherboard. The light doesn't light up or anything.

I also noticed that with my old cooler, I only plugged in the 8 pin connector. Then I added the 4 pin. Both configurations were able to boot to bios (8 and 8+4). When i took it out and set it up on the box, I only had the 8 pin and I got a red light which indicated I didn't have enough power for the MOBO. I added the 4 (8+4) and that light went off but then the yellow light came on.

Any suggestions?

UPDATE: I was able to use the bios flashback button and it worked just like it said in the manual. Powered on and nothing. Not sure if updates it from the USB but if it did, it is now Bios Version 2604

The cooler fans start up slowly, they shut off, and then speed up to what seems to be a decent speed.

remove and reseat the CPU.

I did that already..made sure no pins were bent and that everything looked legit.

Wonder if the cpu died from overheating sorry I am not more of a help.

It was working fine until I replaced the cooler.

Tried replacing the RAM with another stick from another computer. Didn't change the problem.

I meant that the processor didn't seem to be an issue because I could boot into the bios.
