I have a Barton XP 2500+/333 on an Asus A7N8X Deluxe motherboard. Every time I plug in my CD burner, the bios clocks the processor down to 1.09ghz (1100mhz). I turned on the voice alert, and it said "processor failed due to overclocking". As soon as I take out the burner, it works fine. I'm stumped.
