model: asus m6n
cpu: intel 1400 mghz
video: ati radeon 9600 mobility

I run lubuntu 12.04 lts.

The main problem is that today my computer froze several times when browsing (facebook, datamation, ibm devworks - regular stuff) and I had to poweroff and boot to get it working again. It essentially bricked the whole machine.

It could be caused by several things I think. Video card failure, drivers not working properly, kernel panic, the RAM perhaps.

I didn't hear any warning sounds like beeping of any kind.

At the moment it has been working as normal for hours again without any problems.

Is there any way I can view error logs to trouble shoot this sort of thing? Maybe my asus is just reaching the end of its life after 13 years.
