Hi,

I am pretty new to linux/ubuntu so please have mercy....

I installed Ubuntu 10.04 on a relative old laptob... one of the centrino single core no HT cpu's 1GB ram... ATI mobility etc.

It runs very well, however if I leave it on overnight it crashes to such a state where the I have to hard reset the laptop. I don't even know where to start to look for the problem.

I have played music and videos installed stuff removed stuff, even got a virtual box running win 7 (slow as hell, but still), basically stuffed around alot for hours and hours without any hic ups, it is just when it is in idle for a long time (and me not looking) that it seems to crash.

I have disabled the screen saver, set the power management to never shut down or sleep in AC or battery mode.

Any ideas?

Thanks

Think it might be faulty hardware.....RAM comes to mind quickly, but could also be your motherboard or CPU that wants to retire.

Are you fully updated?

Try:

Code: 
dmesg | tail

Once you are back on your Ubuntu right after a crash.

Lol Spot on kingrob

BravoDrie as kingrob has said it could be quiet a few things, to rule out RAM or Swap issues do a "sudo swapon -s" and "free -mot" in terminal and paste the results please.

What about any specific information, how does it crash ? Is it just dead and unresponsive or does the laptop shut off ? Are there any steps that happen during the crash ?

Is Laptop mode enabled ? Type "cat /proc/sys/vm/laptop_mode" in terminal, 0 == disabled, 1 == enabled.

Check logs for errors ?, what the results of "dmesg" and "lspci -k" in terminal

Other than that from what you have mentioned so far, it could be one of many other reasons too so would be a matter of elimination. Hope you can post more details and good luck.
