http://ubuntuforums.org – Hi All I am using a computer having core 2 quad processor and 4 GB memory and I have installed hardy. Now I am facing a non-trivial problem that when I try to run some programs, the computer works for some time and then reboot automatically. This happens when my program uses ~ 100% cpu. Could any body help me to find a solution? Thanks Vinu Vikram (Hardware)
