Praedor, The kt3 ultra with via kt333 chipset should do 133Mhz FSB (266) with no problem. What is your cpu voltage set at? Also, like I mentioned, your power supply might be marginal- especially on the 3v and 5v lines. John's point on another older card causing this is valid too, but then your multiplier on the board should kick in if that's the case to lower the FSB to the pci/agp cards.
I've been reading (and did a lot before when I got my ultra 2)- these boards generally overclock very well, and you should not be having this problem setting it to 133. Take a look at your PS, and see what it's rated at. I've seen a weak PS cause many weird problems like this before.
