Building computer. Assembled..No power. Pls Help
i am building a computer and i have built many before, but never ran into this problem.
i started with hooking powercables to everything. no power. then i hooked up the essentials...HD, Mobo. Turn on, no power. i tried the power supply in another computer works fine.
when i turn on the power, nothing happens. no fans spin, no sounds, no nothing. if something exploded i'd be happy cuz at least SOMETHING happened. but no, nothing.
can yall give me ideas on possible conclusions? is the switch bad? how can i tell? is there a way to power it up, bypassing the power switch, to test is the switch is bad?
i am at a loss. any help would be greatly appreciated.

Do you have another video card to try out? Please list all specs: CPU, Motherboard, Memory, Video Card, PSU, etc.

yeah i do have another vid card i could try, but..if the vidcard is causing it, would that cause the computer to not power at all?

It has happened to me in the past and it was the incompatibility of the video card. What kind of power supply are you using with that system?

You said that you tried the PS in another system and it worked. Have you swapped another PS into this one? Generally speaking you are gonna get power to the PS fan or proc fan even if there is no proc on the MB.

make sure you have read the manual for the motherboard and check that you have properly connected the powerswitch from the case to the motherboard.

Did you try all of this with everything out of the case ? just to make sure the MB isn't shorting out.
If you want to bypass the switch then jump the two power switch pins on the MB together with a little screw driver.
Anyway recheck everything, don't put any cards in except the GFX card (try another card like Conan suggest), use only one stick of ram and make sure a fan is plugged in the CPU fan header.
I don't know if you have built a system like that before ? but your going to need a real good power supply.

but conan wouldnt the psu and the cpu fans turn on even if you had all the cards and IDE devices out and just had the mobo plugged in...of course you would be getting BIOS error beeps.
well do you have another psu you can try on this mobo. I've seen stranger. I have a cat5 cable will only work in my pc. found this out trying to troubleshoot my cousins pc hooked up to my router.
by the way nice little rig you got there.
damn started this reply and got on the phone with a custome come back and theres tons of replies. now thats service.

all you need hooked up is cpu cpu fan memory and video card
with power hooked up pressing the power button will start the computer and you should see a display on screen

oh wow. mega response!! thx for the tips and comments and all that. ima go try the things yall have suggested, and get back to ya.

you can also take the mobo out of the case and set it on the table plug in the vid and memory and see if it fires up. I had a mobo that was shorting on the case.
