[ChokeShot GG]

Heyy guys!

So recently i decided to take apart my whole pc and re-do it cause my cable management sucked the problem i encountere is that when i was done and started re connecting everything back together i forgot the atx 12v 2x4 connector but i had my graphic card hooked up and my pc started for a second and stopped then i hooked the atx 12v 2x4 connector but nothing not even 1 second start when i took it off and i took the graphics card off too and reconnected the atx 12v 2x4 connector but nothing not even the 1 second start it does with the graphics card hooked in ... What could it be and what can i do?

Does your MB light up? maybe a faulty PSU or MB.

What are your Specs?

When i say it starts for a second i mean every fan turns on

My specs are gigabyte z77 mobo with a gx lite cooler master 750 w psu i5-4570 cpu and gigabyte gtx-560

Anyone?

[William12h]

Maybe try cleaning the CMOS and updating the BIOS.

Check everything is connected correctly.

Is your PSU modular etc? check they are correctly connected to the right bits.

PSU isn't modular and i'll check the other possibilities thanks i hope anything of this works

[William12h]

Do you not get any POST? do you have a internal speaker that can do the POST beeps?

Check the HDD cables too.

Edit: just looked and your MB has dual BIOS, try the other BIOS.

I have a thingy attached on the motherboard for the beep but nothing that thing goes off after 2-3 seconds pc starts for only 1 also how can i access the bios since i can start it for 1 second and without the atx 12v 2x4 connected?

Silly question: did you connect the 4+4 12v cable to power the cpu?

I'm a newbie so i'll just tell you what i did i just took a 6 pin cable from my psu and putted it into my motherboard 4+4 12v input

[ChokeShot GG]

So, you connected a 6pin cable to a 8 pin connector?

as far as i know my psu doesn't have an 8 pin connector soo yeah? :ppp

[ChokeShot GG]

lol, i don't think so

If you connected a 6pin cable to a 8pin connector you may have shorted the cpu.

Find the 4+4 pin cable and connect it to the 8pin connector located in the top of the mobo.

So i will take 2 4 pins and put them in the 4+4 am i right?

[ChokeShot GG]

Yes!

Oh gosh it works now .. I thought of that but i remembered that the previous time i hooked only one cable! Oh well thank you so much both!!!!

[ChokeShot GG]

I'm glad to hear it works now

Usually, the 6(+2)pin cable is for PCI such gfx cards, and the 4+4 pin cable is for the CPU.

Good to know from now on so i will stop being a complete idiot with that connector cause it always..ALWAYS gets me ! :po
