Belgian Problem : Four Red Lights

Question

Hello everyone,
I think the "Four Red Lights on D-Bracket" problem is back...  ;(
I have been running a MSI KT3 Ultra with an Athlon XP 1700+ (0,18 µm) coupled with a Thermaltake Volcano 7+ for months now without any problems.
But yesterday my system hung after a few minutes work. As it was the FIRST one I got with this card, I was a little bit surprised but finally thought this could happen even to the best ones...
I simply rebooted but then had to realize there was going wrong with it. My system hangs during the initialisation of my SCSI devices... strange... really strange. I powered off my computer, wait a few minutes and restarted it. And guess what? Black screen with 4 red lights on D-Bracket.
I read the manual and found out that my CPU was wrong. That's really strange because I did not modify anything (no overclocking by the way!)...
I tried to find out what the problem could be by removing unnecessary components (like SCSI adapter card, sound card, network card,...), by clearing CMOS (after I read this nice forum), by re-installing my CPU (with fresh thermal compound) but did not resolve the problem  
Another evidence that my system was correctly installed was the temperature I got during the past months : about 38°C
Do you think my motherboard simply died?  8o
Thanks for your help

I've experienced the four red led lights too. It happened right after I changed the BIOS settings for my CPU internal timing from 'Normal' to 'Ultra'. After I saved the setting, my monitor went blank.
I finally solved it after 2 days. I tried multiple times in clearing the Bios to no avail (5x). So even though MSI says the four led lights is because of a 'damaged or mis-installed proc' it's sometimes not the case.
1. I unplugged the power cable from the PSU
2. I took out the CMOS battery
3. I put the jumper on 'clear' bios.
I went to work for a 10 hour period.
When I got back home, I did the steps below per a forum post I read at work.
4. I press and held the case 'Reset' button for about 30 secs (supposely, it would drain the capacitors)
5. Then I set the Bios jumper back to normal setting.
6. Then I press the 'Reset' button for about 20 more secs.
7. I put the CMOS battery back in.
8. I plugged the power cable backup and crossed my fingers.
I booted up and I still saw four led lights, then the lower right one changed to green and I knew I was in business.
My theory is that somehow, the Bios still retained the 'Turbo' settings when I set the jumpers to clear the Bios multiple times. I think over the period of one day w/ out the battery the BIOS made have defaulted back to the normal settings and/or the addition pressing the reset button drained the capacitor and reset the BIOS.
Sorry the post is so long, but I'm just want to share my experience.
Thanks to all who post and share ideas on these forums!
