Fedora 11 unusable !!!

[Luc MAIGNAN]

Hi geeks,

I caanot work with Fedora 11 on my Dell Vostro 400...

The facts :

- after a while (3 or 4 minutes), I hear the cpu fan starting and at 
this moment, my system hangs up and I have up shut power down...
- I read /proc/acpi/thermal_zone/THRM/temperature but is is correct (40 °C)
- I try to work without ACPI (acpi=off at boot time), but in this case 
my system is too slow... (15 mn to start, too slow after to work...)


Has anyone an idea ???


Any help would be appreciated

Regards
