I have a problem and can't find a solution. I'm really new in linux system, so ask me for whatever you need.
My computer shut down suddenly when I ran some programs (like if I take out the electric power), clustalo tool was the first time, uninstall it, try to turn on the computer and have to use fsck on /dev/sda1 to start correctly. Next time it shut down when I try to compress some big files with pbzip2..., it's happened to me several times and some of them I have to start with the liveCD. So I thought the problem came from RAM. I checked with memtest86, but no errors were found. Maybe some corrupted data?
The computer is Fujitsu, it has 64GB RAM and 24 threads, several hard disks of 2T and is pretty new, less than a year. I use it for bioinformatics purposes and I install lots of tools, but have installed programs such as chrome, skype or dropbox too.
Any ideas? I had looked for a solution but I can't find a similar issue around
Could be when a program ask for more threads than possible? I ran pbzip2 -p16 two times and Ubuntu shutdown again... I hope one of the processes stop or wait,... not a system crash
Just now (10:38:41) I ran "pbzip -p20 my-file" and the computer shut down. When it start again I went to /var/log/syslog and copy the entries around that exact time:

not sure what I'm looking for...
I've tried another approach because only shuts down when asking for many threads. I've run memtest86 multithreading and it fails when is about 55% performed and with no messages, just shutdown and reboot.
