    Trying to build a system for my brother. I put the 3200+ Athlon XP CPU in and with the heatsink. It turns on for maybe a few seconds and then turns off.

    People were saying heatsink but I have tried it on 2, one is the ALK-800A, then some CoolerMaster one. I have to admit the CoolerMaster was originally from my 2100+ setup but still, it's all copper.

    I do notice when I remove the CPU, it stays turned on. I know pretty sure this CPU works as I tested like hours before I put it in my brothers. Cant do that now since it was a quite a drive back home from college.

    Jumpers? Settings? Anything?

    Some things to check.

    1 The hsf is installed correctly. If you install it backwards, the hsf will rest on a lip on the cpu socket. This will not allow heat transfer and the system will overheat in a matter of seconds.

    2 The hsf is plugged in to the correct header on the board. If there is no fan signal, some boards will shutdown.

    3 Have you tried for a post outside of the case? Your system may be grounding to the mounting.

    I was going to post pretty much what crjdriver said. I know you've tried two different heatsinks, but that behavior is suspicious for a heatsink that's not on right allowing for overheating and shutdown.

    Edit: Just wanted to make sure that you are using a thermal pad or thermal grease. The retail AMD setup comes with a pad already on the heatsink. Probably you are doing this, but just wanted to make sure.
