Hello i would like help with adding support for AMD's Mobile Athlon 4000+ CPU (socket 754) on the ASUS motherboard K8N-E . It is an older system of mine and i would like to get it up and running. Before trying this CPU the system was working with a slower Sempron 2600+ CPU which is running fine with the board. 

Well, when i put the 4000+ the PC powers up (the fan is spinning) but does not boot, there is nothing on the screen and there are no beeps coming from the speaker. I have tried clearing CMOS but with no results. 

Now, I found on the internet that the ASUS boards K8N and K8N-E Deluxe work with mobile Athlons and AMD Turion CPU's. Both these boards and the one that i have (K8N-E) have an identical PCB (Deluxe has an added SATA controller with 4 more SATA ports) which you can see from the pictures that I've linked. The chipset of the K8N is Nvidia nForce 3 250 while the K8N-E and the Deluxe version have Nvidia nForce 3 250Gb chipset.  I also found that the DFI LANPARTY UT nF3 250Gb, with the same chipset, officially supports this and other mobile CPU's but it has Award BIOS.

Unfortunately i couldn't find official site for this motherboard but i found the site that has modified BIOS for this board and some of this modifications include Power cycles that would get Mobile CPU's to post so maybe it's worth checking out.

I would love to get this machine running and I am a noob at this so any help would be appreciated!

Ok, I will as soon i put it in the Motherboard.
Sorry it took so long, I didn't have a spare HDD so I had to run Windows from a USB flash drive so it took some time to get everything running. 

Here are the screenshots of CPU-Z:


Sorry I can't help.
