Fedora 4 on Dell Optiplex GX270 Graphics Hangs after update;

[Mirco Scaramucci]

Hello guys,
For the first time I have been experiencing a vey weird problem with my 
system which is a Dell Optiplex GX270 Pentium 4 2.60Ghz, 64Mb Intel 82865G 
integrated graphics, Cmedia CMi8738 sound card.
I have installed Fedora 4 several times and never experienced this problem 
before.
Everything is fine during installation and all runs fine until I perform a 
kernel update and complete update via yum.
I am actually using the yum.conf downlaod from the fedorafaq.org website 
which has always worked perfectly for me.
Only the last couple of times I had to reinstall Fedora after the updates I 
rebooted my machine to log into the new kernel which I think was the 
2.6.12-1447.
I didn't pay too much attention to the other updates so I do not know wheher 
the Xorg configuration was being updated as well.
I did not enable any particular repo during the yum update just a basic yum 
update from basic repos.
After rebooting the machine the kernel gets loaded into ram, udev starts and 
after finishing loading the graphical screen attempts to load but 
unsuccessfully as all teh colours are scrambled and I get blue and red lines 
all over the screen and the boot crashes there.
This problem never occured before during the 10 .000 times I installed 
fedora.
I tried to install othe verious distros to find out whether it was a problem 
with my graphics card but they all worked fine even teh the 3D feature 
enabled.
I also tested verious 3D games and they all worked fine.
Has anyone experineced anything like it/
Is there any updates I should avoid installing to safeguard the 
configuration.
Please HELP. fedora is my very favourite distro, I would say the best but I 
do not seem to be able to jump start this HORREDNOUS PROBLEM.
