Re: Get "CPU changed" message at boot-up
The number of AthlonXP processors seems to have some sort of coordination with the clock speed. I'm not sure, but if I remember correctly, my AthlonXP 2400+ (2.0GHz) died, and they replaced it under warranty. However, it came back to Best Buy with an AthlonXP 2600+ (2.13GHz) CPU in it, but I think it only recognized as an AthlonXP 1600+. The guy at the Geek Squad counter changed the motherboard jumpers and set the speed up to 2.13GHz, and the CPU changed to AthlonXP 2600+. However, I could be entirely wrong, and it may have read AthlonXP 2600+ 1.60GHz, but I thought the number did change.
Check the clock speed of the CPU (see if it changed), and maybe look at the jumpers.
