New PC Build Issues! Help!
I recently bought a loads of stuff to try and make my own pc, some of my friends have already done it so I thought it would be nice and easy (except I forgot I had never done it before myself).

On the first go round I simply went ahead and stuck everything into the case, hoping that when I pushed the power button it would work straight away, this did not happen.

After some failed attempts at getting my pc to work I have decided that my motherboard has a short circuit when it is the case. Is it very easy to fix this as I bought some washers earlier to try and seperate the two but cant see a way of using them? I have used the spacers that came with the motherboard but they are metal, is this normal?

p.s. A general question that I have is why will my pc only boot up when I have single stick of RAM instead of 2?

My pc specs:

Case: Xclio Windtunnel
Motherboard: Gigabyte MA780G-UD3H
Memory: OCZ2G10664GK
Processor:AMD Phenom 2 x4 940
Graphics: ATI Radeon HD 4890
PSU: OCZ stealthxstream 700w
Hard drive: Western Digital caviar black 640GB

If you installed the motherboard without using the standoffs that came with the chassis then you are shorting out the board.

I did use the standoffs but we have the problem anyway. I am still in the process of changing things around so I will update when I know exactly what is going on.

Since you installed memory that is NOT on the approved list for your board, you are in effect a beta tester. Here is the approved memory list for your board.
http://www.gigabyte.com.tw/FileList/...a780g_ud3h.pdf

Next what OS do you have installed ie vista 64bit, xp 32bit, etc?

Does your board detect the correct amount of memory during post?

I have 64bit Vista, when I put in the 2gb the pc starts up fine, but when I have 4gb in it beeps.
I think it does not recognise the extra RAM, does this mean I wont be able to use it?

During post, how much memory does the board "See"
Note gigabyte boards have a splash screen that you can disable in the bios setup to allow you to see the post data.

If you see the post screen, you should see a memory count. Post what it says. Note if your post screen goes by too fast to see everything, you can hit the "pause" key. This will stop the post process and let you read the screen. To continue post, simply hit any key.

I believe that I dont need to worry about this any more. Last night I tried putting in the extra 2gb again and for some unkown reason it worked!!

I dont know how long this will last but the problem seems to be fixed for now.

Is there any major difference between 64bit and 32bit, because I can't seem to find out which one I am running (it should be 64bit) but under screen resolution it only says 32bit max.

I have read that 64bit has a lot of problems with compatibility.
