Woody get frozen

[520066587150-0001@t-online.de (Jerome BENOIT)]

Bonjour:

My fresh Debian/Woody (two processor) computer experiences freezing
when I want to launch jobs as building a new kernel,
computing funny stuff with Maple 7,...
To restart I have to to reset. 

To quickly solve it, I have tried different kernel
(2.2.19;2.4.14,2.4.16),
but it still freezes.
And I urgently need it to make huge computations.

Any idea ?
Is it Woody really on the edge to be frozen ?
How can we figure out the problem ?

Thanks in advance,
Jerome BENOIT
