Ubuntu: Ubuntu 13.04 random crashes


I'm having a problem which seems to get worse as time goes on.

I'm having random crashes (image links at the bottom), It used to happen about once a week or so, but now it happens a few times a day. I had this one 12.04, and hoped that upgrading To 13.04 would solve it, but after a few months with 13.04, it's still happening.

Sometimes it's general protection fault, sometimes page fault, sometimes, something else, And it's on different processes too. Mostly chrome, but not just.

I ran MemoryTest for the night but that didn't seems to do anything.


System info:

Lenovo B570, Intel i3-2310 @ 2.10 GHz 64 bit, 8GB RAM

OS is 13.04 64bit


Something I forgot to mention, and might be important. My machine is dual-boot with Windows 7 Professional 64bit.

Even though I hardly ever log in to my Windows OS, maybe once a month if at all, I didn't seem to have any crashes or anything inside Windows

Any suggestions? I don't want to format my computer if I can avoid it.


Looks like overheated or faulty hardware. Could be the CPU or RAM. Is your machine excessively hot at any place, when the crashes occur?

Test RAM

Install memtest86+, reboot and run it from the grub boot menu. One pass should be enough.

Test CPU

This one's more difficult, because there's no good CPU stress test in the repositories. A simple one would be to run this for a few hours:

sudo apt-get install stress  stress -c `getconf _NPROCESSORS_ONLN`  

Check package integrity

Another possible reason is a corrupted commonly used shared library (think libc). You can check their integrity with debsums.
