Asus A7N8X Versus Chieftec Matrix tower

[IVANHOE7]

My Mother Board will work fine outside of case, once inside it won't post. I replaced the brass standoffs with plastic, placed cardboard under motherboard in case, yet won't post.I placed Motherboard in case on cardboard but not attached and it wouldn't run right but would post. Seems like an evil force is inhabiting my new case. I placed electrical tape around AGP connection around video card, no hardware in PCI slots.

Try taking the power supply from the case and sheild it with the cardboard so it doesn't touch the case. mount your motherboard in the case, plug it all in and give it a try. I've seen it before but in my case, some cardboard sheilding between the brass standoffs worked... ~ The day I think I know it all, i'm changing careers ~

I Tried two power supplies one outside of case that was shielded and it didn't help. I also have cardboard behind Motherboard with plastic standoffs

Have a close look at where the peripheral connectors come through the back. Anything look fishy? If that case has a removable back atx plate, mount the board in the case, but without the back plate.

The only other contacts with the case that I can think of is with the video/ports/audio... have you checked to make sure you have the right plate in the case for your MB style? Can you make sure these contacts are fitting right and not touching the board? I've seen times that the metal tabs fold into the usb ports too. hard to see unless you're looking for it. that's the only other thing I can think of.
There has to be contact somewhere.

Try taking the plate right out of the case and mount the board again making sure that the video/audio etc are not touching anything... ~ The day I think I know it all, i'm changing careers ~

Are you wiring up all the front panel headers when the motherboard is in the case? could one of these be wrong?
I have to say I haven't had very good experiences with the Asus A7N8X, out of the first few we built none would run properly (I won't even list the things we tried) but trust me the wholesale supplier was happy that we had tried everything before he agreed to accept the whole order of these mainboards back.
I still think many issues with this motherboard are down to memory type/make and bios revision but we tried all sorts of combinations before we gave up on them.
Gone to the Leadtek and Abit Nforce2 boards now and can hapilly report no problems to date (only built 3 with the leadtek and 2 with the Abit) so early days yet.

I have only video card attached with electrical tape around metal and have remove plate for USB, mouse, keyboard ETC. Still doesn't work. In fact it starts acting funny with Motherboard partly inside sitting on cardboard

Finally fixed it by putting rubber washers under the plastic posts, it then worked in case lying on side,but wouldn't right side up. Finally I taped Valcano fan upward on case since gravity was putting downward pressure on CPU. Should have got lighterweight cooling fan.

This all sounds very unsatisfactory and definately NOT a permanent solution.
You could cause irreputable damage to you processor because of inadequate heat transfer to Volcano heatsink/fan.
Something is faulty and needs changing, either the motherboard, case or power supply so don't try to make do, get it properly diagnosed and the offending hardware replaced. Martin Replying helps further our knowledge, without comment leaves us wondering.

My computer's CPU is running cool since I taped my fan to case, it was a gravity problem not a power supply, case, or mothboard problem. Just a Volcano fan problem. So if anything I need to get a lighterweight cooling supply paparazi.

You have totally lost me!
I didn't understand a word of what you just wrote.
Anyway good luck and i hope all is well.
