Hello,
I will explain my problem,
I had a functional setup, then I bought a new case, and while changing my components into my new case, I believe I reconnected everything properly. However, when I turn on my PC, the fans, hard drive, and LEDs light up for about 2 seconds and then shut off immediately.
I have no idea what to do now; I think I have done the necessary tests with 1 RAM stick and then both, I completely removed my graphics card, disconnected the hard drive, and checked the BIOS battery which was dead. I found one that is half full... I hope that’s not the problem... What I don’t understand is why it was able to start before if the BIOS battery was dead...
So right now I have no idea what the issue is, and I need my computer quickly...
Thank you in advance for your response!!
Feel free to ask me your questions

Good evening,
Regarding your change of case, an idea immediately comes to mind:
Have you CHECKED THE NEW CASE to make sure you didn't leave a fastener of that type (see link) UNDER THE MOTHERBOARD... I mean where it's not intended. If that's the case, you are certainly causing a short circuit on the MB.

You must leave only the spacers that correspond to the mounting holes of your motherboard. Imagine if you leave one that is not aligned with a hole... this spacer could very well touch the circuitry of the motherboard. I'm saying this for your own good. Remove the motherboard and CHECK that all the spacers are properly aligned with a hole... after that, you'll know for sure that there are no errors on that side and we can try other avenues.
By the way, have you properly reconnected the power cables = 24-pin connector + a 4-pin or 6-pin depending on the motherboard model?

Check that by moving the motherboard, you haven't shifted the CPU cooler. Make sure the four fasteners are properly in place and that the cooler is firmly seated on the processor.
If the processor is SLIGHTLY off-balance, it will lead to an IMMEDIATE overheating of the processor, which will protect itself by shutting down the system.
Otherwise, any PC will start without the BIOS battery; it’s only there to save the time, date, year, and any changes you’ve made in the BIOS. If the battery is dead, you’ll boot using the default BIOS settings.
Also, check that your system hard drive is properly reconnected to SATA port No. 1.

Did you properly connect the power/reset buttons and LED????.... only leave the POWER button and try again

I just checked and the fan on my processor seems to have come off, the four fasteners have been removed if I'm not mistaken!
I have connected the SATA port to SATA6G_1!
But nothing works, it still doesn't start. For the connection of my buttons, I only connected the Power SW; I had tried with all the connections properly plugged in and now I'm leaving just the Power SW...
I'm lost...

You mean the heatsink was no longer making contact with the processor ... if that's the case, you may have "fried" the CPU.

I only see this as a solution because we have gone through EVERYTHING and believe me (I’m not young anymore) I have assembled many machines and we have gone around.. yes, if the radiator has come off the processor, that could be the cause of the failure to start and in that case...!
If... there’s still the power supply... did you take the one you had or is it a new PSU?

Ok, go check online to see how to properly reinstall the CPU cooler mounts.
Otherwise, it doesn't take too long... you take apart the power supply, motherboard... lay everything on the table and make your connections like that on the table (not a metal table, right?)
To start it, use the tip of a small knife that you place on the pins (where the power button connects)... if it starts, there's a grounding issue... or something else with your new case.

In this case, you need to find another power supply.. and never remove the CPU cooler to "see" if the processor is hot.. first of all, if it is really hot you risk burning yourself and you also risk frying the processor which won't have had time to dissipate the heat.
Another thing that worries me too, when you say: I even tested 26 pins without plugging in the 4 pins.
First of all, it is not 26 pins but 24.. let's move on.. what worries me is that you tried by only connecting the 24-pin connector.. by doing this test, it prevents the processor from being powered correctly and if the requested current is too high, it will pass through tracks (circuits) that are not meant for it and that is not good for your motherboard.
In any case, do not put anything back in the case .. unplug your power supply and go to a repair shop so they can test it.. it only takes 2 minutes with this type of device

If the power supply works properly, everything suggests to me that you made a.. mistake (to be polite) somewhere.

When I say to find another power supply, first test yours before buying a new one... it might be... (and I hope) that it's your power supply that's failed.
In fact, a power supply costs less than a motherboard + a processor ;-)

Yes, regarding the pins story, I must have gotten confused.
I went to a computer store to bring my motherboard, so they will keep it until tomorrow afternoon when I will pick it up, and then they will give me the verdict. I'll keep you updated on the progress...
To come back to the story of the pins, I was powering my motherboard with the large connector that has a total of 24 pins + another 8-pin connector next to my processor.

Well, there's nothing left to do but wait for the verdict, hoping that the problem is with your power supply; otherwise, you'll have to buy a new tower... like this one for example

Hi Sergio39,
I successfully retrieved my PC in its new case, I asked it what it did, and it said that it didn’t try to understand, it just took everything apart and put it back together, and it worked on the first try, so it doesn't have much idea about the problem...
In any case, this new case works perfectly with all my components, but aside from a few connectors from the case (fan) that the technician doesn't know where to plug in... they are all powered, but we don’t know what they are for.

Hello,
in my opinion, if nothing has been changed, you must have got tangled up somewhere with the buttons/leds... it just can't be otherwise.
Anyway, the main thing is that your new case is operational.
As for the connectors, if they are "Molex" they can correspond to front lighting, and if they are for fans, later you can buy a "fan controller".
Best regards... and thanks for the feedback... don't forget to mark your post as "resolved".

Thank you for your quick response,
The case has already been used so the black spacers for my case were already in place, I just moved them to fit my motherboard format which is an ATX if I'm not mistaken, so I left them there... should I leave them between my motherboard and my case, reassure me..?
