kde takes a nose dive

[john brennan-sardou]

Hello,
       I don't think I have done anything out of the ordinary but kde 
and gnome keep taking a nose dive with the message "signal " and 
"Sigserv" all over the place and  I suppose Sigserv means signal for the 
serveur and of course this only happens in graphic mode. My video card 
is a winfast with a nvidia gforce fx on it. It seems to me that the 
problem is here. Also each time I try to "yum" into livna I get a 
segmentation fault. I should add that this computer contains an above 
normal quantity of via parts (which I deeply regret but life is like 
that) Any ideas how I can get out of this one please?
