Ubuntu: Ubuntu 13.04 random crashes



Question:

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.

Images:

System info:

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

OS is 13.04 64bit

EDIT

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.


Solution:1

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.
