I'm new to linux, I just installed mdk 10.0 with the 2.6.3 kernel on my HP Pavillion ZE1115 with an AMD Duron 1.1 ghz processor. It's working great, except that when there's a heavy load on the CPU the computer overheats and shuts down. I've installed ACPI and ACPID and enabled ACPI on the bootloader through drakeconf and I'm still having the problem. I'm sure I'm missing something obvious, but is there any way to automatically throttle the CPU when it starts overheating?
