Not enough information here, Sandy.

Which version of Ubuntu are you running? (meaning off which boot menu 
are you running "memtest").

Instead of doing this memtest from the boot menu do it from the 
installation CD. Tell us what the result are.

For my limited knowledge, I suspect that there is problem with the RAM - 
"insufficient low memory".

What shows up when you check the BIOS settings? Waht does the BIOS show 
as basic memory and then the rest? Do you have BIOS configured to shadow 
video and whatever? How big is your "video window" (for the videos card) 
set in your BIOS?



ATTORNEY:  The youngest son, the 20-year-old, how old is he?
WITNESS:   He's 20, much like your IQ.
