I think this means your IOAPIC is buggy. It happens on a lot of systems and you need to boot with noapic (this means that the ioapic will not be initialized -- not sure why it's ok with windows, maybe windows ignores the ioapic?).

To permanently enable the noapic option, edit /boot/grub/menu.lst, look for the line that looks like:
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=3f139ec0-654b-4f61-9fc8-7aa8cbb3f738 ro quiet splash

and add noapic to the end of that line.

After a reboot, it should be ok.

Edit: You should also add this the the defoptions line in menu.lst so that it looks like this:
# defoptions=quiet splash noapic

Thanks for the advice.

I have done what you suggested me to do but the game still freezes

I more or less get the same error message in dmesg but now without the APIC error

I have looked through the dmesg file and i have found some messages that i think maybe could mean something

[ 18.512000] Asus Laptop ACPI Extras version 0.30
[ 18.512000] unsupported model G1S, trying default values
[ 18.512000] send /proc/acpi/dsdt to the developers
[ 18.520000] No dock devices found.

[ 19.676000] Failure registering capabilities with primary security module.

[ 20.388000] apm: BIOS not found.

[ 16.784000] lp: driver loaded but no devices found

Does any of these messages explain my problem??

Not that I can tell.

Is this a game freeze of a system lockup? Can you press control+alt+backspace to kill Xorg or control+alt+f1 to go to console and kill the frozen process on the command line?

If it's a game that is hanging, but the system is still responsive, this is likely a library problem or a problem with the game itself. Or it could be a bug in the video card driver. Are you using the proprietary (restricted) nvidia driver?

I have just tested when my computer freezes and i found that the system is responsive to control+alt+f1 and then killing the game.

I used the restricted drivers manager to install the proprietary driver for nvidia.

The system also freezes when i play tremulous. But then it only freezes for 2 sec or so and then it is running fine again. My computer have also frozen while i was using openoffice(Don't know if this is relevant).

Have read somewhere that an APIC error 00(40) could mean that i need to update my BIOS-could this be the case and if it is how do i do it?

This is sounding more and more like a video card driver problem. Or possibly opengl libraries.

You could try reinstalling the nvidia-glx driver. Looking at apt-cache search results, I see nvidia-glx, nvidia-glx-new, and nvidia-glx-legacy. I don't know why there's multiple nvidia drivers (I don't have any nvidia cards). Maybe someone else knows more about this and can help?

I guess I would at least try reinstalling nvidia-glx and seeing if that helps, and maybe remove the old driver and install either the new or legacy driver and seeing if that works better.

To reinstall the one I believe is installed:
Code:
sudo apt-get install --reinstall nvidia-glx
from a terminal.

As for the APIC errors, as long as they aren't showing up anymore in dmesg after booting with noapic, it shouldn't be a problem (ie, there are no errors). Since this problem persists without the error messages, it probably isn't related to the apic. Just make sure to keep booting with noapic.

I updated my BIOS yesterday, apperently i have been using version 2.04 but now i should be using the newest version-300..but little has it helped.
My Laptop still freezes when i play games, and i tried you suggestion with the drivers, and the one that works for my laptop is the nvidia-glx-new. But the system still freezes.

Is it it of any importance that some patches of the screen goes black and other patches goes red, blue etc(like there was some signal malfunction) during boot and shutdown?
-this happens wheter i have installed my video card or not.

This also happens when i boot with Vista, but still the computer doesn't freeze when i play games.

I'm not sure what the problem really was, but i installed ubuntustudio and now i have been playing tremulous for 2 hours in a row without any problems

Thanks for your advice, i have learned something about Ubuntu using them..
