Case problems, grounding out?

having a really odd problem. Its some sort of raidmaxx case, a 50$ variety. Now, ive got a GB Ds3 and e4300 installed in it. If i bump the case in any way, remove the door, it reboots. Im thinking maybe something is touching the motherboard tray metal on the underside of the motherboard.

does that sound like my problem? Is it new case time?
 
Easiest way to check stability, (as far as a grounding out issue,) is to pull the board out of the case and set it up on the MB box or something similar and run it for an extended period of time, see if you run into the same issue; if so then you've got a grounding issue which is not related to your case but your board.

I ran into an issue on a 680i board where one of the wleds for the screw holes wasn't clean, (had some runs in the solder,) everytime it contacted with the standoff it would powercycle. Pulling it out of the case allowed me to diagnose this.
 
is this a pretty common issues with cases? or its more of a motherboard thing?

i bought a DS3 from MWAVE, it was a refurb, and im wondering if its a lemon. its been great otherwise. its only warrantied for 15 days, so im thinking ill pull it out and see what happens.
 
will i get the same effect if i pull the board out, and maybe put a screw in each hole, and just attach to the MB tray, only outside the case?

there are no spacers between the bottom of the MB and the MB tray, i wonder if im just missing something on my install
 
I would assume if its a pure short between the case and the standoff's and or case you would be much less likely to get a 'clean boot' more likely a power cycle where it doesn't fully boot but it spins up then stops and repeats.

I don't think this is a common problem with cases, more with the boards... being that its a refurb checking outside of the case would help to determine where the problem is. I would set it on the board box, (not on the case.) another good thing to check would be to make sure you've only got enough standoffs that your using, (if you have an extra in there it could be shorting against the back of the board.
 
i dont have any standoffs installed, maybe thats my problem? there is nothing in terms of hardware between the motherboard and motherboard tray. I seem to remember before this build using these sort of " screw extensions. Maybe these are standoffs? they were about 1/4 long, the screw going through the motherboard hole would go into the top of the extension, and the bottom of the extension would screw into the board.

im wondering if this is the same thing as your "standoffs", maybe this is the problem!
 
If the motherboard tray is completely flat then yes....definitely your problem....miracle you haven't turned your mobo into a crispy critter. Some less expensive trays have the standoffs built into the tray.....small bumps on the tray with srew holes in them, if so then the standoff will make your board sit too high to use the I/O shield.

if thats what your talking about, i havent had any installed, so the bottom metal parts of the board have been in contact with the metal tray, this my problem ? :)

i found 5, that should be enough.

This is a MAJOR problem ! You will need motherboard standoffs that should have came with your case. If you don't have them you will have to get some there are a few basic types.

1. They screw in and on the other side have a hex-head that is threaded so you can screw your motherboard's screws into that.

2. They have a square hole in the case and kinda snap in a square standoff with threads that allow you to screw your motherboard's screws into that.

3. something similiar just take your motherboard out and look at your case, it's best to find the standoffs that came with your motherboard.

Seems like you don't understand that connecting everything on the back of your motherboard electronically is very, very bad! You are lucky that it still works. The only place that should be touching metal to metal is where the screw connects to a metal "standoff" that connects to the case. All the standoffs do is connect the motherboard to the case on little legs so it only touches where it should.
 
yes i do understand metal on metal is bad. It was an older case, thus no little packy with hex standoffs. When i was building it, i thought something wasnt quite right. anyhow, its fixed.
