Hi :
I guess the same as Rick in this case. It might be a BIOS problem.
You can try a patch for your video chipset (intel 852/855). Try this URL
http://www.chzsoft.com.ar/855patch.html
download the 855patch.tar.gz and do something like ;
tar xfzv 855patch.tar.gz
cd 855patch
make
su
cp 855patch /sbin
/sbin/855patch 16384 // or 10000 (this solved my problem).
^^^^^ ^^^^^
Then reboot and stare at !! Good Luck
