Specs : i7 6700k, z170-k Asus motherboard, 8GBx2 Corsair vengeance 2400mhz ram, GTX 1070, relatively new PSU deepcool pf550(bought oct 2023)

From the past week my computer was shutting down on its own and i was getting anti surge trigger warning when powering up again in bios.
This was followed by a storm nearby my area which had led to a transformer change aswell so i thought it was due to that.

Few days ago I had problems turning it even on so i removed a ram module and it worked fine, I even tested it on valley benchmark so my conclusion was one of my ram sticks was effected and the power supply and other components were okay.

Today I find my computer is unable to turn on again even if the ram stick removed, although I have to say these ram sticks have been the bane of my existence every time I move or clean my computer I had to readjust then 3 to 4 times until I see the boot screen again, maybe the storm was the final blow my ram couldn't handle.

My question is how do I be sure that the ram sticks are causing this problem and perhaps not motherboard being faulty(maybe it has loose slot instead of ram being faulty), I have tested my ram in multiple slots, it works in 1,3 slots sometimes(yes I have to re seat it alot) but never works in 2,4 no matter how many times I re seat it, does that mean my motherboard slot is faulty? or perhaps the PSU although I have stress tested it and it was able to handle full load for quite some time.

I have no problem buying a new set of ram but I'm a little worried if my motherboard is faulty there are no models I can replace it with, i can only find motherboards smaller than atx and which do not support overclocking, Please Help me, Should buy new ram or would that be a waste.

Hello, due to the warning message that you have received, I would first troubleshoot PSU, if you have a spare one, try that. Also make sure that you have a good surge protector/smooth AC power. Another thing to try is checking for any shorts on the case and motherboard, perhaps even bench testing the setup.

If you can get the system to POST/boot, you could run memtest86 on the RAM, to make sure it is stable/no errors showing up there. Lastly, if you have eliminated memory and power/electrical problems, then I would suspect the motherboard. At that point it might be best to start looking at a new platform upgrade.
