Gnome has become unstable

I am running SuSE 10.2 on a Dell optiplex GX400 with an nVidia GEFORCE2 
GTX video card.  I tried to install the proprietary video card drivers and 
erred.  I installed drivers that were too new and no longer supported my 
card.  When I deleted them I found that the open source driver no longer 
worked and X froze up.  I then tried to install 
NVIDIA-x86-1.0-7182-pkg1.run.  I then found out this would not work with 
the 2.6 kernel.  So I installed NVIDIA-x86-1.0-7185-pkg1.run.  This did 
work and I have a working video card driver.  I am left with 2 problems I 
can't figure out.  Frist, Firefox crashes when ever I go to a novell.com 
website.  I am addressing this on the applications forum.  Secondly, gnome 
has become unstable and is constantly crashing and recovering.  I've had 
to switch to KDE.  How do I go about troubleshooting and fixing what is 
wrong with gnome???
