I would like to share to fellow vogoners a very special situation encountered!
In one of my old systems I tried to upgrade the cooler from stock to an aftermarket one.
Specifically I am talking about the following configuration:
Athlon XP 3200 with original AMD cooler.
Abit AN7 with nforce2 ultra chipset
2*1gb Corsair CAS2
80gb SATA HDD
The CPU was running quite hot with the stock cooler - 55degrees at full load. I bought a brand new Arctic cooling copper silent 3 designed for socket 462 and installed it. The system starts and immediately shuts down with no beep and post code 9A. tried everything from starting the system barebones with just 1 memory module and the graphic card; change memory, CPU, graphic card and nothing. The system will not post!! I tried all the original components on another socket 462 system and they ran just fine! I thought the motherboard was toast so I put a Duron with the stock cooler and the system started right away!
I fully assembled the original configuration with the stock AMD cooler and BINGO - beep and post all the way to Windows XP! I tried the same cooler on another socket 462 board with the same results: no POST even if the fan was runnning just fine!
The conclusion: just use original coolers from 15-20 years ago and put a case fan and not to mess with modern up to date ones!
