Computer does not POST

[Perzival31]

A couple of weeks ago my computer stopped working, I had an old case and power supply, around 450w. A Gigabyte GTX 960, i5 4690k and a MSI Gaming 5 Motherboard. 8gb of Kingston fury ram. A 480gb Kingston SSD and a 300gb old hard drive. Then it stopped working, it did not post. It would turn on for a second then turn off, the fans would spin during that time as well. I thought the power supply could have been broken so I bought a new EVGA Supernova gs 650W and a new case while i was at it, a fractal design s. I installed all the new parts and it still did not work. So I ordered a new motherboard, an ASRock z97 extreme6 and a new NVMe SSD, intel 600p. I also bought a Cryorig h7 to see if I could do a little overclocking. I get all the new parts and put them into the computer, and it works. I overclock the cpu to a safe 4.4GHz and clone the old ssd onto the new one and everything seems fine except the motherboard had some coil whine so today i tried to disable the overclock and the computer stopped posting again like it was doing with the old motherboard. Anyone have any idea what is going on?

Try flipping the CMOS jumper or re-seating the CMOS battery to reset the BIOS.

 

Re-seat all connected cables, expansion cards, and RAM.

I tried that, it did not work.

I tried re-seating the CPU and surprisingly it worked, for like five minutes. I was able to get it to post, but not load into an operating system, I think that may be a bug with Haswell motherboards and NVMe SSD's. But then the computer stopped working again. I re-seated the CPU again and it worked for like thirty seconds. Any idea why this would happen?

There may be some dysfunctional pin/socket connection? Are any of the pins bent?

[Perzival31]

It did not look like any of the pins were bent, they are small though so I could have missed something. Is there a good way to check if the pins are bent or any other dysfunctional thing about the socket?

If I turn the power supply off and wait a while then it will boot, but then will give me a 99 error, which the manual says there is something wrong with the PCIe device, so i took out the SSD and graphics card and waited and tried again and it gave me the same error.
