    Default EP45-UD3P Fried. Urgent help please!

    Hi all,

    I am building my first system and I have(had?) the Gigabyte EP45-UD3P.

    I installed the processor, heatsink and ram outside the chassis and then installed the motherboard with screws at 9 places(as is shown).

    I did not use any spacers, washers or such. On the reverse side of the board, there is metal strip that I assumed keeps the gap between the motherboard plate and the board.

    When I started the box, nothing would start. I thought that some screw is short. So, I removed all the screws and just placed the board on the plate and started it. Voila, it started just fine.

    At this point, I assumed that if a screw is short, the box won't start.
    So, I then put one screw and started it. Started fine.
    I put another. Started fine.
    I put one more. 'Phattttt'. The chip on the left of SYS_FAN2 gave a spark and got fried.
    The board won't start anymore.

    What did I do wrong? Did the screw short the board and cause this?
    Or is it something else altogether? Is it the PSU? What options do I have now?

    Can somebody please help me?

    Thank you
    Nilesh

    I dont want to be a doombringer ,but with only 12v running thru your mbrd a "phzzzit" and a spark sounds terminal.The chip to the left of the sys-2 fan header..? little black one with sata 2 stamped on it?

    Your mbrd should work without even being in a case as long as everything is connected up properly.Ie it doesnt need any screws at all.

    You could try connecting everything up with the mbrd outside the case again or just leave the mbrd suspended on the sheet of sponge that came with it to ensure there is no electrical contact with all the little solder spots on the mbrd,but then theres a risk of damaging the other components,if they havent been already.
    I dont know what you mean by a metal strip between the mbrd and the backpanel of the case.There should be no contact at all between the back panel of the case and the mbrd except at the 9 suspension points.

    The mbrd mounts on 9 metal "pegs" which are supposed to provide clearance between the mbrd and the case panel.the screws go into these pegs/posts and so the mbrd is held a few mm cear of the back panel.
    You usually have to insert these little pegs to line up with the holes on your mbrd before screwing it to them

    Some cases come with a little packet of brass posts that thread directly into the back panel,others with posts that need a nut recessed into the back panel before they can be screwed in.

    Im assuming you knew all this and didnt try and screw the mbrd directly to the back panel?
    If someone tried this there would be lots of pfzzt and sparks.

    Best bet would probably be to return to supplier for a replacement or refund "its not working".
    Altho were not supposed to discuss rma's etc on the forum.
    I just hope its only the mbrd thats gone.

    Also before next build google things like "how to assemble pc components","how i built my pc",that sort of thing..just to be sure.

    Or even "rescue" a fairly modern pc from your local recycling centre and pull it apart just to see how the parts fit together and the mbrd is attached to the case.

    I'd check the finish of the case where the screws go (don't know the name for them in english) they are a bit above the plate and should feel smooth with no metal coming out from them.
    Otherwise it may be something on the board, check the area of the hole that caused the problem, both front and back side of the board.

    Unhappy Re: EP45-UD3P Fried. Urgent help please!

    Thanks a lot for responding.

    Sorry if I am sounding like a noob, but from what I know, the circle around a hole on the board is kept isolated right? As in it doesn't directly connect to any circuitry on the board?

    The screw set I received did not have any pegs/posts.

    Oh well, guess I am screwed. :(

    You did not get any of these... Brass Standoff

    IF you didn't that is/was your whole problem... but if your board is fried not so much ne more. Newegg?

    I didn't get any of those. :(((

    Yes. Newegg. I have bought a 1 yr replacement warranty as well.
    Will I get a replacement?

    I am very worried abt other components though. I don't have any warranty for those (and it's beyond 30 days) AND I have no more money to buy new stuff.

    Gosh, this is a very bad day for me.:(

    Those stand offs should have came with your case I believe if you ordered one. On your other parts just have to wait and see. Did you try it again out side of UR case? May just need to purchase the stand offs or get them from the case manufacture (if new case).

    I don't know this but I think Newegg resends out items that have been previously returned. JMO

    Not being able to see the case or know what brand it is ..perhaps the "standoffs" are built in already? Usually tho when buying a case they arent already fixed on because different motherboards types(size format ,full atx like yours,or mini or midi atx) have different mounting points.

    Yes the holes in the mbrd the screws go thru are isolated theres no circuitry near by and the screws arent needed for "earthing" .Theyre just to hold the mbrd steady and to keep all the solder/contacts on the back clear of the metal behind.
    Even with the "standoffs" there is a chance of contact with the back of the mbrd with flexing etc.
    Some people put the sponge that came with the mbrd behind it (psycho 101's tip) or maybe some thin cardboard with holes cut in it for the pegs.

    If the case doesnt have them or they didnt come in the screw packet.. it would seem v bad marketing.

    Depends on the case. In mine the holes for the screws are like small bumps that are few milimeters above the plate, not need for the stand offs.

    I have the Cooler Master Elite 330.

    As Kick said, I figured the holes are electrically isolated AND if you check the 4th pic in this link
    Newegg.com - Computer Parts, PC Components, Laptop Computers, Digital Cameras and more!

    you will see metal strip in the center. I thought that is there to prevent the solder/contacts from touching the metal behind.

    So, I did not use any standoffs.

    I think what happened was, when I tightened the third screw, somewhere the board touched the plate and it blew! :(
