I ended up shutting it down and replugging cpu didn't work any more, and i was baffled why it did the first place, on my way to check everything again it does seem video card has some sort of contact issue with it's slot, i also tried in other slot, it didn't even work there, and if i screw the card like i am supposed and was for all the years, it doesn't seem to work, so i left it without screw and started the pc multiple times and it works.
I didn't rule out motherboard issue despite never having one, i am just a user so my experience is limited, i had countless power supplies die on me, this doesn't look like that kind of issue, and playing around with other parts didn't have any effect.
Thanks, i just keep my eye on it, if it keeps going just without a screw that works for me, if not ill be closer to actually replacing the correct part instead of being told to buy a new pc in store
