Could anybody help me?

I built a new computer: ASUS A8N-E motherboard, AMD Athlon 64 3200+, Sonata 2 case with 450 Wt power supply.However, the first boot failed: no beep, nothing in the monitor.

All the fans work, "power" button turns the power on but cannot turn it off (even after pressing it for 4 seconds as instructions say), "reset" button doesn't work either. I did the minimal boot: only CPU, memory (2 sticks) and videocard. Everything is brand new. I have checked all the connections several times, re-placed CPU 4 times - nothing!!! No beep!!!

I had the same problem a couple weeks ago with ASUS A8N5K. That time I made a decision that the motherboard was bad and I replaced it for ASUS A8N-E. However, the same sad story...

Could anybody help me???

Thank you for your time.

Hi,

Have a look at this guide and see if it helps

Have you tried out of the case as the guide suggests?

Could you provide a link to the case and psu?

Is there a case speaker connected?

Could you possibly try another video card without purchasing another?

Thank you for replying me.

The good news is that it boots.

I followed to instructions I found in the Internet... I put out my mobo and power supply out of the case and put it on the table, I removed CPU, memory, videocard and all connectors. Then I added 1 memory stick, CPU with heatsink and cooler and videocard connected to a monitor. And... miracle happened - in 20 seconds I heard so long-expected beep and my monitor became live. I couldn't beleive.

Then I thorougly put all the construcion into the case - no problem any more!!!

I have no idea what was wrong initially. I repeated those steps several times but without videocard...

Another thing is that the beep appears after 15-20-30 seconds, so maybe I was not patient enough in some of my previous tests after many failures when everything was installed in the case...

Again, thank you very much! I think all the user guides should start with recommendation to make a minimal configuration on the table and test boot.

I normally do that with all new builds at least that way you are sure the main components are good.
You could have had some kind of case short or something was not seated correctly

Your welcome glad the guide helped and your fixed up.
