did i short my mobo?
Discuss did i short my mobo?
Posted by: lord nikon007
i just bought a new case and moved all my hardware from the old one to the newer one but when i connected everything and pressed the power button the fans lit up for a second and then everything just died. i unhooked the optical drives and tried again..same thing. unhooked everything else and just had the mobo powered and still the same thing.
have i shorted the mobo from touching it too much or something?

You probolly forgot the 4 pin molex power connector. Or the PSU had some charge, but it was not recieving power
Posted by: lord nikon007
yeah i have the 4 pin connector in place as i checked that one like first thing. in terms of the PSU getting no charge what can i do to fix it? will i have to get another board?
Posted by: jerry5739
i would say yes. becuz my first pc i ever assembled was built on my carpet...and it did that same thing u speak of....i RMA'd it and it worked fine afterwards...but that doesnt mean u shouldnt try a few other things first and rule them out ...
Posted by: lord nikon007
but what else can i do to make sure that its not just my mobo thats jacked? i mean its cool with all the advice but what can i do to make sure that thats whats problem

I'm unclear, were you grounded?

i was sitting on the ground...i thought that counted as being grounded? but its not distributing power to the entire motherboard thats why i think theres a short somewhere.
and the screwdriver i used i think had a magnet in it. that affect anything?

Are there any beeps?
Posted by: lord nikon007
no..no beeps..just a flash of lights from the fans and then it just shuts down

Check your processor and bios chips are seated properly, and everything else come to think of it.
Always switch off the PC, unplug and touch the metal case before touching components. Handle components/ cards by their metal edges, normally chrome and not the edge connectors etc.
Doesn't sound good though.
Could be your power supply, as jerry 5739 said. Can you get hold of another to try?
Posted by: lord nikon007
i took all the stuff out and stuck it into a completely different case...smaller power supply by 50W but still should have run and i still got the same thing. fans kicked up for a second and then died.
still think its the power supply or is the mobo really shot?

take out all the extra card and other parts and start from basic. If the bare bones work (IE - CPU/HDD/fans,etc), then add a part. then if that works add another part, etc... until you find out if a part is acually faulty or not. it might just be that something was shorting out your system when completely built.
This very same thing happened to me at one time, and now that same mobo that I thought was dead, is now in my son's computer :)

I agree with Nukem, but you can take it right down to barer bones, pull all the bits out of your case, pop your mobo on an anti-static surface (just to eliminate the chance of your case shorting the board), plug in a video card, PSU and CPU (with HS/F), you don't even need RAM as far as I remember, ditch ALL of the drives and make sure the monitor is plugged in :) then power it up, that should eliminate a number of potential faults.
Add bits one by one, testing it by booting after each component added.
Hope that could be of use.

Did you forget to put those pins on the case behind the mobo, so that it isn't sitting directly on the inside of the case. (I don't know what they're called, but someone must know what I mean)
Posted by: CJJohnson
Spacers, posts, Standoffs, they have many names.
Just a word of caution, an anti-static surface could very well be conductive by nature. Those nice shiny bags that your mobo comes in look metalic for a reason, they are and they conduct electricity.
Just a wild stab in the dark. What position is your CMOS (BIOS) jumper in. I have heard of motherboards being shipped with the jumper in the shorted, or "Clear BIOS" setting. That could cause the problems that you have.

Sounds like PSU ios the first thing I would be changing out!

He already has, it is possible for 2 Supplies to be dead though, unless it is a known good one.
