Ubuntu – Ubuntu 14.04 64bit – computer shuts down by itself


After I installed Ubuntu 14.04 64-bit on my Lenovo ThinkPad T61 today, I could boot up Ubuntu without problem but after I run the Software Center, Additional Driver, or Firefox, the computer will shut itself down. Could it be possible that the 64-bit version is not compatible? I used to use 12.04 32-bit without any problems.

I don't think that's the likely cause, if your computer was incompatible with 64-bit linux (x86_64) it would not boot at all. I would check the fans, it may be overheating. You might also check the power settings.
