BIOS "freezes" a few seconds after started

Hello,

I have just set up a HTPC-setup in a streacom FC5S cabinett. The setup is based on a Asus F2A85-M LE motherboard with A4 5300 CPU. The streacom is a fanless cabinett which uses heatpipes to take away the heat from the CPU.

Anyway, I finally finished the installation with almost no problems, and when I first booted up i got in "POST"-mode a error message: "CPU fan error!". (this is no surprise since I have no CPU-fan.). I pushed F1 to enter BIOS, which is functioning for about 5 seconds before the screen "freezes" and I am not able to do anything. When I mean functioning I mean that I am able to navigate in the menu.

I now have to reboot the computer to get back in, and same prosedure, it happens again. I am able to see that CPU-temperature, RAM-temperature etc is on low level ( 36-38 degrees before the screen freezes).

I have tried disconnecting and connecting everything again, and I have also disconnected both optical drive and harddrive with no change. I have also tried with both of the RAM-modules separately with no change.

Anyone who has any idea what could be the problem here?

Sorry for my badly written english, bere with me :)

The CPU Cooling Block requires thermal paste. Did you use any? It isn't included with the case but can be purchased separately.

Hi, yes I used thermal paste at all the contact points specified in the instructions that followed the streacom cabinet and the heatpipes. Including in between the CPU block and the heatpipe-block.

Power Supply - Quietpc.com recommends using a fanless picoPSU which can provide up to 160W of power. This is more than enough to power a CPU that has a TDP of 65W.

If you read the motherboard manual, you will see that the recommendation is for a minimum 300 watt with at least 15 amps on the 12 volt line. The system may be unstable or not boot up if the power supply is inadequate.

Hi, I must admit i read this after I connected it all. But it does not make sence compared to what I've read on other forums etc. My impression where that this motherboard is well suited for this kind of buildt.
