CentOS - Sep 2008 - Strange browser displays with 5.x on Dell GX-260

I had been running CentOS 4.x for quite some time with no problems. 
Apparently I stubbed my toe when installing CentOS 5 final.

Symptoms:  various web sites are not properly displayed in Firefox 3.0.1 
(or predecessors).  In particular, cnn.com and any calls to Google 
display with a screen full of ascii characters rather than images.  When 
I look at "page info" within Firefox, it shows "quirk" mode
rendering
rather than "standards compliant" mode.

BTW, I'm running the same version (in fact, using the same DVD iso) on 
my home machine, a Gigabyte system I've cobble up, with no such problem.

Any ideas out there?

Thanks,
Dick

Only a "WAG". I'm using Firefox 3.0.1 on CentOS 5.2 (32 bit) and
just
looked at CNN (International and U.S. versions), with, as you see
at home, no problem(s). Possibly a Graphics issue? Did you "Upgrade"
from CentOS 4.x to 5 or did you do a "Clean" install?  BTW, I had
issues with Firefox 2.x, with Gmail.com for example, that went away,
after I upgraded to CentOS 5.2 and got Firefox 3.x.  I think there
were major library changes, from CentOS 4.x to 5.0 and if you
Upgraded, something may be awry. Possibly remove Firefox and then
install again, in case something is corrupted. GL
