14 - okay. You didn't follow the manual and instructions provided with your motherboard?

Yes there is a specific way you'll need to connect the wires

A popping sound from your power supply would mean its either dead, dying or is shorting -> bad for your components. A generic power supply is bad since it can either go out with a fireworks show, set your house on fire or leave you with a sad smiley. It might've lasted all these days with your previous card but even we are not sure...


thats the part where i had trouble, i don't know where the p+ and the p- , and the powerswitch etc went. the part where i took note of is when my other case had a "power reset" cable, and this case didn't
 


yeah, but i also notice that my motherboard has no light to it. does it mean that my motherboard isn't receiving power and i fried my whole computer?
 
^ Very helpful information. NOT.

zestou,
is it possible to pass on what sort of a chassis you're trying to perform the transplant and having issues with the power button? [strike]In any case I'm going to assume the chassis a cheap case with unlabeled connectors.[/strike]

You can trace the cables from the power button upto the connectors and that will help indicate which ones are which and you may need to open up the cases front panel to help with your tracing. Colored cables usually help as well got a pic of the cables?
 


We're not up to there yet. My guess is that you haven't plugged the cables from the case into the correct spots on your motherboard.

Your motherboard manual should show you where to plug what connector. The connectors from the case should have stamped on them what they are for. This needs to be married up with the info from your motherboard.

 




motherboard: asus h81m-e
cpu: i3 4130 3.4ghz
ram: 4gb ddr3
gpu: gtx 650 ti 1gb
storage: 500gb
2 case fans, 1 normal cpu fan.
powersupply: generic 550w (but it was able to run a gtx 650 ti)

btw I'm using a nzxt s340 case
 
I apologize, I mistook that you swapped to a cheaper case and thus couldn't read the connectors labeling. According to the manual for your mobo pin 2 and 4 are Power+ and Power - respectively.

Provided the connectors for your cases' front panel are labelled Power+ and Power -

* Generic? That would require some screening through our eyes 😉
 


can you please explain that? I'm only 14 years old not knowing that you meant exactly haha. btw, i notice a popping sound from my power supply after putting the power cable into it. this only happened after i switched cases.

also, are you saying there is a specific way to put in the power connectors on my motherboard?

Zestou,
I've received your PM but I thought You and anyone with a similar issue will find it beneficial and helpful.

If the S340 chassis doesn't have the reset connectors then I think you can;
a| contact the case manufacturer, NZXT, or the people who you bought the chassis from and notify them of the issue
b| you won't require a reset button since most hardware won't be causing an issue we once used to see back on Windows 98 and XP :)

As per your PSU - remove and replace immediately. In order to figure out if the existing hardware is working you'd need a donor PSU and connect it to your system to check it out. If not then you're flying blind. If the components don't fire up with a donor/new PSU - then you've lost them to that generic unit 🙁
 


i'm freaking out man 🙁 I'm getting my computer checked up today and ill message you what happens
 


Hey! turns out that everythings fine! considering this was my first time dismantling a case and putting it in a new one. the guy told me that i just put the P+ and P- and etc in the wrong place. my computer is working fine now :) ill learn from my mistakes
 


after the guy fixed the wiring there was no more crackling and popping
