DAMN. WHAT ELSE? The mobo i have is P5N E SLI (Asus bought in 2007, 0401 BIOS)

Now I have another issue. My mouse/keyboard freezes immediately at login window and the only option is to reset or POWER OFF.

I have a Logitech optical mouse/keyboard and a 2nd USB mouse. Both work fine in my laptop. Batteries just changed. I tried several times
to plug/unplug, boot/reboot, but nothing happened. If I continuously move the mouse during OS load, I can see for a few sec (3-5) the pointer
moving. But immediately freezes. All USB options from Advanced in BIOS are enabled. Thanks!

P5N E SLI is ready for Linux and 2.4 Kernel or later.

If I reboot with no mouse/keyboard plugged, BIOS lets me know. > plug in mouse/keyboard>DEL>BIOS>F10>load Ubuntu>
move mouse and keyboard arrows during boot >login comes up: mouse and keyboard freeze after 2 sec.

I can see the keyboard is functional too because it changes the user but immediately freezes.
I won't update BIOS, I don't think this will solve anything.

I apologize but I don't know anything about SATA controller. I have some RAID options... I don't see anything
about SATA controller in the manual. Maybe I am missing a line. (?)
Anyhow - this new issue upsets me more now. Is still my mobo?
Can I do something to see grub load info? How? thanks a lot.

UPDATE
Well, I tried it last time for today and it worked. BUT I logged on a different account and I got this message:

I chose not to, since I don't know what this is. I read some posts and it looks like a bug that comes and goes, waiting to be fixed.

Will continue posting with my new happenings. I gave up SATA for now. Will try and learn more BIOS but...still cannot see anything regarding
more SATA options. Will continue look in this one too.

It's been 3 months or so since my last post. I did not purchase a new PS. I did check all my connections step by step and nothing was bad. My last resort was to reinstall the OS. But this time I also created a new OS image at a very low speed.
I was not surprised to see that the installation went on WITH NO PROBLEMS (At the very beginning the 1st 2 attempts couldn't install bootloader. I fixed that issue from Ubuntu help website). Now, after the clean installation, everything was recognized and works good for months. Many thanks for your ideas.
