Question After upgrading my PC it doesn’t turn on, the fans only spin for a split second, and it shuts off ?

Okay so this might be quite long... so today I bought new ram (ddr4 vengeance 32gb) to upgrade from my ddr4 veangence 16gb. I also bought a new 1tb sata Kingston ssd. And finally a deep cool ls520 liquid cpu cooler. I installed the ram, the ssd and finally the cooler. However for the installing of the cooler I couldn't manage to find the pin for the 5v D Gnd on my motherboard. However I found a cable around the back that fit it. Also a 5v D Gnd. I knew this prob wasn't the best thing to do and I think but I'm not sure but this might be what broke it.

Anyways I started it up and it just sort of stuttered. The fans spun for like less then half a second and then stopped. I immideatily turned the power off and unplugged all other cables from the cooler to the mobo. I realized that I hadn't installed my got so I tried that and booted it again without the cooler installed and still the same stuttering problem. I switched back to my old ram still didn't work. Did I ruin it or is it save able? Any help or tips would be very appreciated!

DO NOT connect those cables to the new power supply or you will risk destroying the drives. Use only the cables that came with the new power supply.
Yeah ik, is it worth changing all the cables now and attempt to plugin all the drives with the correct psu cables and see if that solves it or is unlikely that that would change anything?
 
Wym by following the rest of cables? The one for the cpu is also marked H1-08 on the side that goes the psu and so is the the motherboard cables so I think so yes
Exactly what I was referring to. Thanks!

At this point, following the above warning, connect the drives using the new cables. Get your PC to boot into Windows. If successful, power down and install GPU and corresponding power cable.

If you receive the same warning, make sure power cable is fully inserted into GPU.

Yeah. Pinouts aren't standardized in psu industry and you'll 200% short circuit. Do remove old cables.
Yessir, do you think by doing that and reinstalling drives with new cables that it could solve the gpu problem? (Just to clarify, I haven’t connected the drives to the psu at all, the old cables are still connected to the drives but not any psu, the reason is I thought I would test out the most essential bits first)

Okay, I will replace all my drive cables and get them up and running with new cables and new psu, do you want me to attempt to boot to windows with integrated graphics and if that works, then install the gpu?

Okay so I’ve now got my new psu and it works, pc turns on and runs. However the ez debug vga lights up and my screen displays the ”please power down and connect the pcie cable to the graphics card” I’ve tried reinstalling my graphics card and the pcie cable (which of course is connected already). Only thing to note is that I haven’t connected power to any of my drives, but I doubt that could be the problem right?
Make sure both ends of the PCIe power cable(s) are attached to the GPU and PSU (assuming modular).

Very possible. Higher quality PSUs help to prevent peripheral damage in event of power surge or supply failure.
Okay so I have a bit of an update. I let a computer shop try my gpu and they got it to work no problems. Now I doubt my psu is the problem. I’ve tried two pcie cables and all the different ports on my psu labeled cpu&pcie. They are the same on the psu and fyi my cpu works well. It could also be my mobo perhaps but everything else works completely fine. Fans, lights, ram etc etc. I’ve also tried the two graphics card slots on my mobo still didn’t work. Could it be as simple as me performing a bios update and gpu drivers??? I really can’t find any explanation. The bios thing doesn’t make sense either because why would that happen now?

The PCIE slot could be damaged. Try a different slot for testing.

It we'll see. If it doesn't work it needs replacing which requires removal anyway
Well well, I will be gone for a couple of days, I will bring my gpu with me to try it in a friends system, perhaps update some drivers etc. When I get home I will preform a rebuild outside the case. I will probably ending up buying new cpu and mobo. By the way, there is a pc repair shop, they charge quite a bit for a diagnostic run through but they are very good. If I rebuild the pc outside the case and it doesn’t work, can we be certain of the problem or should I let them have a look anyway? And another question, how would I go about powering on the pc if it’s not connected to the case?

You short two pins on f_panel header on motherboard. They should ne labeled "pwr +\-" or similar.
