MSI KT4AV 4 RED LEDs WON'T BOOT

Question

Hi.  I recently purchased a new MSI KT4AV motherboard, new AMD Athlon 1.33 Ghz CPU, and new PC2100/DDR266 DIMM RAM, and when I turn it on, all 4 LEDs on the diagnostic bracket light up RED (meaning processor failure).  Does anyone know what could cause this?
My system specs:
MSI KT4AV motherboard
AMD Athlon 1.33 Ghz 200 FSB CPU
PC2100/DDR266 DIMM
420W PSU (+3.3/28A, +5/40A, +12/18A)
Hopefully that's enough to diagnose any problems because it won't output any video, just 4 red LEDs on the D-bracket.
Thanks.

Hello,
When I bought my second KT4AV, I was planning on using an Athlon T-Bird 1.4 I had laying around in it.  It had the exact same problem as you are having, it just didn't work.  I then tried a Palomino 1700+ I had in a another computer that I knew worked fine - it was (and still is) in a K7T266 Pro2-RU - and it didn't work either.
I was thinking the motherboard was bad but I bought an Applebred Duron 1600, and it worked perfectly!  So it would seem that even though they are listed as compatible, the older Athlon T-Birds and Palominos simply will not work.  My advice to you, buy an Applebred Duron, or better yet, an T-Bred XP 2000+.
Sorry if that wasn't what you wanted to hear!
