Homebuilt computer won't power on for unknown reason

[ShootyMcFace]

I recently built a computer with my brother, and after installing Windows and all the drivers on it, we powered it off and moved it to the room that it would be used in. When we plugged it into the power in the new room, it would not turn on (no lights, no fans, no output of any kind). What is wrong with the computer? Please help

Is anyting maybe shorting the motherboard out?

Did you accidentally turn off the switch on the back of the PSU? Is there any chance it's plugged into an outlet that doesn't work or requires a switch to run on the outlet? What is the model number of your power supply? Any chance something got knocked loose inside?

As far as I can tell, nothing was knock loose, and all switches that should be on are on, but still no boot.

The PSU is a Rosewill Capstone 750w 80 Plus Gold
Here's the link if you need any more info about it: Power Supply

Try a different power source (plug it in another socket).

Yeah, I'd try it on a different outlet and let us know. If it worked fine when it was moved, it should work fine now. That's a very good PSU so it's doubtful that it took a shit from one room to the next. Try plugging a lamp or something into the same outlet that it's on now to see if it works.

Tried that, still no boot

Can you post apicture of the system, maybe one of us can spot a problem

I moved it back to the room where it was working, but now it won't boot there

Have you tried powering it on with the reset button instead of the main power button (if your system supports it)?

Sure, sorry if they are shit quality (took them with my S3)

Yes

 

[Bossyfins]

Can you try with another PSU?

 

[ShootyMcFace]

Can you try with another PSU?

Unfortunately, no because I don't have an extra one. Do you think the PSU is the problem?

 

[Bossyfins]

Maybe, On the back of the PSU, is there an LED?

No

Try the PSU paperclip test to see if it is dead.

 

[Bossyfins]

Yea, try that. IF the systems fails to power up, you most likely have a dead PSU

 

[smorizio]

make sure the mb not screwed down to the mb tray and shorting out. make sure you use the right stand off and screws so the mb not shorted out. try posting the mb outside the case see if it posts fine and there not a dead short in the case.

 

[Bossyfins]

I doubt its shorting because it powered up before he moved it.

Just did paperclip test, and no response from the PSU

 

[Bossyfins]

Dead PSU.

I recommend either an XFX, EVGA b2/G2/P2, SeaSonic, or Antec PSU.


Stick by these PSUs, and you will never be sad, well maybe once it dies.

Would this be a good one?
Antec 750W

That hurts. but atleast you now know the problem part.
Just as a word of advice, check out your power outlets for proper earthing and supply before powering it on with a new PSU next time, just to be sure.

Thanks for the tip, I will take it. The outlets should be grounded, but I'll also check out a new power strip while I'm at it
