I recently got a new Ubuntu 10.04 desktop at work. However, the machine crashes every few hours, and the video output would stop. I suspect the issue is related to the drivers, so here is the "lspci -v" output:

Anyone know what might be happening?

Based on your data, you are using a sandy bridge based chipset.

Since ubuntu 10.04 came out in 2010, and sandy bridge came out in 2011, you are using an OS that is older than your hardware. Drivers will not even have anticipated what the technology is in sandy bridge.

Running older OS on newer hardware usually leads to problems (especially linux where the drivers are usually made by the community and not the manufacturers).

Try using a newer version of ubuntu

I updated to Ubuntu 12.02.1 LTS last week. No more crashes so far. :-) –  Danny Chia Jan 22 '13 at 22:00
