Question Since yesterday, my PC has been crashing non stop. It was a couple times yesterday but it's every second now. I think it's the PSU.

So my PC is relatively new. A year old.
So whats been happening is that today, my PC crashes every single time after I login to windows or even on the login page. Like instantly restarts in 10 or so seconds Everytime.
I did the basic diagnosis.
First I cleaned the inside and took everything apart and put it together, no change.
I ran chkdsk on my ssd and no errors. I reinstalled windows again and formated my drives.
I reset the bios.
I watched the temps in the bios since I can't do it after logging in cause it crashes.
I ran windows memory diagnostic but PC restarted during it, like crashed.
Happened once with chkdsk too.
Sometimes after it crashes, every light on my PC flickers for a couple seconds like they're not getting enough power and 10 seconds later , it launces and restarts again.
Tried individual ram sticks, no change.
Tried safe mode once, it didn't crash on there and it didn't crash when I was in the bios. Every other time, no matter what it is, it just restarts again and again.
What am I missing? What else could it be?

Corrupt OS install.

Already tried to reinstall. No change

Maybe it is a bad PSU. Weird thing is, usually the PC would shut down if that was the case. Not restart.

Specs?

That's what I meant by restart. It fully shuts down, power turns off to all parts, 4 seconds or so later, it starts again

It starts when YOU turn it on or it starts up by itself?

And "Corsair 650W" narrows it down to about ten different PSUs. VS, CX, CX-M, CS, Vengeance, TX-M, RM, RMx, RMi, HX, AX....

Update, it crashes Everytime now. No matter what. I mean even in bios, windows recovery tool. Doesn't matter what it is, after PC boots, it restarts anywhere between 10-30 seconds later. It restarted on its own all this while, however it's not doing that anymore. Now it just stays off until I manually power it.
Vengeance.

Well, if you think it's the PSU and obviously it's still under warranty, have it swapped out and see if that helps.

Fixed. Changing the PSU fixed the problem.
