Intel DP67BG - Case is causing a short - need help!

post #1 of 17
Thread Starter 
I am having the worst time ever with this motherboard. I haven't been able to get it to post since I got it on Monday. All that I usually get is the power button flashing continuously when I turn on the power supply, along with a slight clicking noise coming from the area near the power button. I am pretty sure that this means there's a short somewhere. At first I thought it was my Hyper 212+ that was causing a short so I reinstalled the Intel stock cooler. I can get my board to power on successfully when I breadboard it, but the minute I try installing it in my case it will not power on and I just get a flashing power button. And it takes a long time for the board to be able to turn back on. I have to take out the CMOS battery and wait at least 3 or 4 hours, probably longer. I have tried just waiting an hour and reinstalling the battery but that doesn't work. I don't know why it takes so long for the board to be able to post again after I have the battery out.

I thought that maybe the I/O plate was causing the short so I reinstalled the motherboard without the plate and it still wouldn't power on. Now I am thinking that I must have a short occurring between the standoffs and the screws. This board needs 10 standoffs but I only have the typical 9 standoffs in my case. Do you think not using one of the standoffs is causing a short? Also maybe my screws are a bit too large? I am using the same screws with my Crosshair IV and I have never had a problem. I also used the same screws in a previous rig without any problems.

I guess the only way to find out where the short is is to try installing one standoff at a time and powering on each time to see if it starts. That's such a total pain in my rear! If I use cardboard washers between the screws and the top of the motherboard would that be OK? Do you guys have any other ideas what the problem may be? Should I try to RMA with Intel?

Also my case isn't a problem because I am using it now with my Crosshair without any problems. I only have one case so I need to reinstall my Crosshair every time I am done testing the Intel DP67BG.

I would rma just to get a non intel board but thats just me.

try this. line the entire case floor with card board or rubber so that no metal might be touching the case. I had a short problem like this once and it was cuz the mobo was somehow touching the metal of the case just barely.

once the wall of the case is lines install and try. if no luck start with standoffs with just the four corners (these shouldnt touch anything other than pcb). see if that boots. If it does install one standoff at a time after that to see if it will boot. Also you say ur using 1 less standoff than the mobo has holes for. Where is the location of the hole that has no screw/standoff?

The standoff hole that I am not using is the one circled in yellow.

I hooked up my Intel board outside of my case again and it worked, of course..LOL. I even installed my video card and RAM and I even took the opportunity to update my BIOS. Guess it's off to radio Shack or someplace close by to buy some motherboard standoffs and screws. UGG

Its not a massive problem if you're missing a standoff, but I would switch the missing spot to say the bottom right, because the hole you have circled holds a lot of the weight from the graphics card.

Something I did when my old TRUE was shorting out my board: cut a ziplock bag into a sheet, and poke holes in it so that it lines up with the standoff holes. Cheap, effective, antistatic sheet between the board and the motherboard plate.

have you examined the backside of the motherboard with a magnefying glass? there might be a bad solder job on a trasistor or something, or a small peice of metal that was supposed to be trimmed that didnt. intel isnt exactly known for the quality of there boards so it would not suprise me if there was a defect of some kind on the board itself.

Thanks for the help guys, especially for the zip-lock bag idea! I hooked up my board again, today, outside of the case and it worked. So I then installed it in my case and turned it on and once again it didn't work! Go Figure! Anyway I will try using a ziplock bag later tonight and see what happens. Unfortunately it seems like I can only troubleshoot my board just a couple of times each day because after it shorts out in my case it takes HOURS before it will turn on again for me. I have to take out the CMOS battery and leave it unplugged outside of my case for at least 4 hours. I don't know why it takes so long for the board to recover. I thought maybe an hour at most would be long enough but it's not. Is it normal for a board to take that long to recover?? Anything that I can do to make it recover quicker?

next time it shorts out. take it out of the case but leave power button connected. Remove the battery and press power a bunch. This should help to get the power outta the board sooner. I am only guessing at thats why it wont restart as the cmos isnt fully reset yet.

did you get this sorted out yet? let us know if you need additional assistance. nothing more stressful then a board that shorts itself out. you might look into using a different kind of standoff. something thats non-conductive (not sure if this even exists).

if after fully examining the back of the board with a magnifying glass and examining the standoffs/standoff holes you still cant get this solved, i would rma the board.

also i dont recommend trying to power this thing on while its in the case anymore until you get this sorted out. there has to be something making contact where it shouldnt. examine your mother board tray with a magnifying glass as well. check, and recheck your standoffs are in the correct spots, check that multiple times.
