It shows on startup ''a new cpu is inserted in your system'' with asus m2n68-am plus. its brand new.

You might have a combination of several small problems. I would like to know whick processor you have installed. But Here is how to get started:

1) Open the case (after unplugging the PSU, not just turning it off). Use a wrist grounding strap or touch the bare metal on the case frequently.

2) Pull the jumper off the 1st two pins of the RTC. Place them on the 2nd two pins for about 10 seconds. Pull them back off and place them back on the 1st two.

Plug the PSU back up and turn on the computer, pressing delete button when the fans come on.

3) This will enter the set up. Check to see if the correct CPU information is listed now. If not, the bios is not old enought to recognize the CPU.

4) activate Asus Update. Go to the site and update your bios from the site. You will have to clear the bios again after the new bios is updated.

5) at that time the motherboard's bios should recognize the CPU. This happens frequently with Asus boards particularly where you have an AM2 board or AM2+ and you are installing a Phenom AMD PCU.

Let me know how this works. There are other things we can do. This is the only thing about Asus boards I dislike.
