I just upgraded 12.04 64-bit. When I run some code in matlab, the computer is always dead or it restarts. I couldn't figure out the reason.

Although video card on the motherboard is only 32MB, I have Nvidia video card and choose primary video card to be other in BIOS.

Can you give me some suggestion? Maybe first, I can start with some test to see the health of computer.

You could install memtest, and run it from the bootloader. This will detect hardware issues with the main memory. If matlab hits a defective memory section, which would normally not be used, this can easily cause the problems described.

Also keep a watch on memory usage and CPU temperature while runnung matlab. If the memory rund full the OS kernel normally starts killing off processes, normally this doesn't cause a cold reboot though. If the CPU overheats this can be the cause of system freeze or reboot.
