Comment 43 for bug 271070

I have the same problem,
It takes a long time to load, then
"starting up...
[ 0.004000] Aperture beyond 4GB. ignoring.
Loading, please wait...

Ubuntu 8.10 pancho-laptop tty1

pancho-laptop login:"

i log in and then i get a whole load of information about my last login, and how ubuntu software is free, and how there is no warranty. then i can enter commands.

When it is loading, the screen turns off and on a couple of times.
I have a compaq presario r4000 amd athlon 64. I recently upgraded to 8.10, but it has been working alright since today, and i cannot turn the laptop on.
I am quite new to ubuntu so don't know what to do.
i have looked around, but cannot find anything.
