Help: Unknown weird booting problem

[Zack Nguyen]

So for some weird problem, whenever I turn off my PSU (the switch on the PSU), after I turn it on again, my PC wont boot. The fans are spinning, but the screen doesn't display anything. I had to unplug a ram and insert it again to boot. If I don't turn of my PSU, I can boot just fine.

An additional information is that I have bent my socket pins on my z97 motherboard before I see this problem, I fixed the pins myself, stress tested my cpu with prime95 and things seems to be ok. I do not know whether the problem is the psu, the cpu, the motherboard, or the ram 🙁(

My system spec:
CPU: I5 4690k cooled with phanteks tc12 dx
VGA: R9 290 watercooled with corsair h60
MB: Gigabyte Z97x ud5h BK
PSU: FSp Aurum Pro 850w
2 120gb ssd and 1 1tb hdd

Temps on both CPU and VGA are ok, CPU max at 65 degree C at 4.3 ghz in prime 95, VGA peak at 60 degree full load
