PC Not Booting

[mowzeh]

So I just had a huge surge from a passing thunderstorm and now my PC is not booting. Well not normally anyway. Initially when the surge hit everything in the house turned off then back on, so I immediately turned off the power point to be safe in case of another surge. After letting the storm pass I turned the power point back on and the PC wouldn't boot. So I sat of my chair for a few seconds then got up and pressed the power button again and to my surprise the PC booted, the only thing was the PC was not registering the ethernet cable plugged in. So I grabbed my notebook to make sure it wasn't the modem but it worked fine for the notebook. So I decided to shut down the PC and start it up again but it would not boot back up. The only way I could get it to boot is if I turned the PSU switch off then back on and pressed and held the power button for 15-20 seconds then release and press the power button again. This led to the PC booting but only for a few seconds before it would turn back off. The LED on my CPU AIO watercooler is working and for the few seconds the PC boots it posts but then straight away turns off. I have tried re-seating everything and re-plugging all the PSU cables as well as resetting the CMOS and changing the CMOS battery. The problem still persists, to get the system to boot I need to turn off the power supply from the rear of the PC, wait for the LED on my CPU cooler to turn off, then turn the PSU back on and press and hold the case power button for 15-20 seconds then release and press it again for it to boot, but it always just shutsdown after approximately 10 seconds.

Has anyone encountered this and had a solution? I am hoping it is the PSU but my gut is saying it's the motherboard. I am not in a position to be spending a lot of cash and so I want to be precise in determining the problem. It also doesn't help that my CPU is a haswell on a z97 chipset meaning I've got to lay out a big sum of money for a new motherboard.

Thank you in advance for the help.

CPU: i7 4790k
MB: Asrock z97 extreme 4
RAM: G.Skill 2x8gb Kit 2133
SSD: Samsung Evo 840 250gb
GPU: Gigabyte g1 gaming gtx 980
PSU: EVGA 750w G2
CPU Cooler: NZXT Kraken X61

The surge may or may not kill your PC components, you will have to test the components one by one.

Start with the PSU, using the "Power On Self Tester" to see the PSU is fine or not. Then remove the gtx980, just boot the PC with onboard intel iGPU. Next if you can test the RAM, hdd, etc in other PC. Even take out the cpu, and check it ( or the cpu socket) there is any burn mark or not. If you don't any compatible components, and you may ask your friend or local PC shop for help.

sounds like your psu made some parts of your pc go bang.

Thank you for the suggestion, I remembered that I had a software bug error when the PC booted the one time after the bug so I disconnected my SSD and I am now able to boot, I get into the BIOS and am able to load my RAM XMP profiles and all my other hardware is registering. So it's clear that now I need a new SSD and to spend a few hours reinstalling windows and all my other software. I have not been in the market for an SSD for years, are there any recommendations? I am not fussed with ultra fast speeds I'd just like to be able to load things quickly and more than anything have reliability. Thank you for your help. One last question though, when i removed the SSD I had to press and hold the power button then release and press again to boot the first time, but now it boots as soon as I press the power button, is there any reason for this happening?

Spoke too soon, I decided to turn the PSU main switch off then on to be sure, and it is doing the same thing as before. I don't think it's the motherboard though because when it was booting normally I was able to access the BIOS, does this sound like the PSU?

Recommend to buy 500Gb size, like Crucial - MX300 525GB or Samsung - 850 EVO-Series 500GB.

For the 2nd question, during the boot, the PC does the POST ( power-on self-test), it will reset and reload the boot loader code to your new boot device, because the your SSD may have problem, which you said to spend a few hours reinstalling windows and all my other software.
