New hardware, dead computer

Hi!
I have started building my new computer now, but it doesn't boot. I have tried my PC analyzer card, and i get the following error code:
A3: Soft error display complete. Going to set the keyboard type matric rate.
I have no idea what this means, but my VGA monitor is connected, and a working keyboard is connected. I use the following hardware:
Motherboard: MSI K9A2GM-FIH (new)
RAM: 2x Crucial DDR2 PC4200 2048MB (new) and 2x identical used 1gig rams
Video: Integrated
HD: Samsung 500gig, used
Old HP DVD rom
New PSU

I have hooked off every buttons and so exept for the power button.
The screen is blanc, and I have NO idea what to do.... :-o
thnx in advance :cool

 

Btw, I use an AMD 4400 am2 processor, but this is an AM2+ mainboard. But doesn't am2 cpu work with am2+ mainboards?

 

Lets start at the beggining.. When you start the machine is there lights on the motherboard and are all fans starting ?? is your activity light (usually red) on the front of computer on.. is it stable or does it reach a point when it starts to Blink. Check that your screen cable is well in its sockets and tight disconnedt and reconnect if it makes no difference try another cable.. Try that then post back. here is info on the bios error codes......

The fans are starting, but I haven't connected te activity light. I have tried the screen on my laptop, and it works fine. I use the VGA port on the mainboard, and I don't have another video card connected. I get error code A3, and I found a list of AMI error codes on the analyzer card homepage. Code A3 wasn't listed there, so I have mailed AMI to find out what the error code means. It doesn't make any difference with or without RAM and drives. All cards, front panels and so are disconnected, so either the brand new mainboard is broken, or the used CPU is broken. I am going to get another CPU to try with, but any other suggestions are appreciated

 

Could this possibly be as simple as it halting because it doesn't recognize the keyboard? Is keyboard ps2?

 

I was thinking about the same thing, but I have tried with a PS2 keboard (working) and wothout keyboard, and it is no difference.

 

Have you got a Video card you could put in and see if any visuals come up ??

 

Only the one integrated in the motherboard. I don't get any output on it, and I don't have any pci-e cards rolleyes

 

Have you connected the 4 pin extra power cable to mobo. yellow and black cable near your back panel connectors.

 

I hope this is not your problem in the links below but if you pan through there it may give you an answer. Do you have the manual that gives you the max cpu voltage ??

Listen to Toke and AMI since I know little of POST.

Just want to give you a link of error codes. It looks like the various tests are done in order to complete POST and hand over control to BIOS. You are halting near the end with A3. There are however several keyboard checks/commands before A3. What this means I don't know.

The extra 4pin plug to the CPU is connected. But after looking around i found this:

I was told it was a 4400+ AM2 CPU, maybe replacing this would to the trick :confused
And I don't know too much about the PSU, other than it is a 400W. A friend will bring a brand new phenom to try on friday. If it doesn't work I am returning the mobo and buy a new one with a new CPU.

 

Is my 4400+ a 125W CPU? And I looked on the website were it was bougt, and found this: https://www.komplett.no/k/ki.aspx?sku=343333&view=detailed#ProductTabs
The guy i bought the 4400+ from said it fitted both AM2 and AM2+ motherboards. :mad
I will get a phenom to try on friday.
If not I will return the motherboard

 

The power is plugged in, but I think the old 939 processor doesn't work with my motherboard. It isn't more than 80W or so... New phenom processor ordered, and maybe it will solve my problem.
Thnx for help everyone
