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!

I was having exact same problem for last couple of weeks. I was doing a new build with a Z790 and had plugged the atx cables in backwards. 🤔 Only took two weeks of trouble shooting to figure that out.
Double check the power connections and the cpu installation. There is nothing you did that should cause this power issue.
 
Yeah, but still lets check the least obvious things that came to my mind.
1. Reseat CPU
2. Check if that cables from your case don't cause shortage, you said about RGB's, that it stopped working
3. All those cables that you connect at the bottom, maybe one of them got loose?


Intel from 12th gen and AMD from 7000 series support only DDR5 ram. Depends what do you wanna upgrade to. DDR5 ram is also more expensive than yours.
Ohh okay, I thought you meant I had to buy new ram if I buy a new motherboard for my old cpu

I reseated all the power cables yesterday. And i haven’t touched them during installation of my upgrades
 
So I tried the paperclip test, the psu fan spins for like a split second and then it turns off, a second or two later I get the click noise that my psu makes when it shuts off, the fan spins like the rest of the case fans in the case did for like a second. I’m guessing this indicates that my psu is broken and maybe not the motherboard! I did check and my psu from Corsair does have i think the temperature controlled fans, however it shouldn’t have the clicking at the end right?

Edit: I tried it again a couple of minutes later and now nothing happens, perhaps I should try getting a new psu and try to see if that solves it?

I’m omw to pick up a new psu to see if that could solve the issue, are there any known problems with plugging in a new psu to a mobo or other parts that potentially could be fried already? I wouldn’t want to damage my new psu by potentially plugging it in to broken compenents?
 
Yesterday I think I accidentally killed Some components by plugging in a cable incorrectly. After some further trouble shooting I found that my psu has stopped working, I’m omw to pick up a brand new psu to attempt to see if that works, in other words try and see if the psu is the sole problem or if the motherboard etc has taken a hit too. The test I preformed was the paper clip test which showed signs of life att first, spinning for a split second before shutting off never to turn on again.

Are there any risks with plugging in a new, working psu with components that may or may not be fried?

Not really. Just swap.

Thank you, just bought a new psu and omw home to test it, I’m scared to death other components are broken tho. The mistake I believe I made was not finding a 5v D gnd add header on my mobo and plugging it in to a fitting cable hanging losely in the back, I’m scared that it might have passed through the mobo shorting something on there. Is there any precautions I should take when trying the new psu? Say unplugging everything from the mobo and attempting to run with only like the mobo power pin and the cpu pin? No fans etc since they might be fried from the incorrect cable connection I made

You won't know what is damaged until you swap to a known, good PSU. Improper cabling is definitely a way to zap components.

Good luck.
 
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?

Did you replace ALL cables with the new PSU?
Basically, the motherboard cables, cpu cables, pcie for graphics card and a power cable for the case are all connected to the new psu with the new cables included with the psu. The old cables from my broken psu are still connected to all the drives but they are not plugged in to any power. The point here was not to get my pc completely up and running and working just to see if my new psu solved the old problem which it by the looks of it has. I doubt me not having my drives powered would have anything to do with my graphics card not working atm right?
 
Correct.

Now, check to make sure you have the GPU power cable installed in the correct port on the PSU and you have the cable direction correct also.
Okay, my gpu power cable is hooked up to the one of the cpu & PCIe outputs on the back of my phanteks amp gh 750W. The end that is plugged in to there is labeled H1-08 the other end hooked up to my gpu is labeled PCIe, is that correct?

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.
