Gonzalo, I used to have that problem. My computer would freeze in Windows when ever playing a 3d game. I found it would freeze spasmodically using Linux. The problem was with my mother board and a buggy ACPI component. Now I have ACPI modules installed and I have not experienced a freeze.
Hope that helps. BTW, I have not tried other cards I have a Nvidia GeForce 4. > Hi All, > > I'm experiencing complete (and random) system freezes every day or two. > I've not found a pattern yet, it happens at random.
