Ubuntu drives me crazy. Since I upgraded from 11.10 64-bit to 12.04 Ubuntu crashes regularly. One time the crash report tells me that Skype is the faulty app, another time it was Opera, and today the crash report tells me Xorg crashes.

I read that it can be caused by a faulty upgrade so I made a clean new installation of 12.04 32-bit. But the error is the same. I had a look in the log files with a friend but we did not find a answer.

This morning the crashes happened like this:

  1. Boot
  2. Auto-start Thunderbird
  3. Start VLC for radio
  4. Start Opera
  5. Working a while (30 minutes)
  6. Starting Skype

2 minutes later, the system freezes, the monitor turns black, a login screen appears and I enter my password. The desktop comes up again and the crash report pops up.

Possibly a hardware problem? CPU, motherboard? –  Jakob Jun 2 '12 at 8:14
    
Like Jakob said, could be a general hardware problem. One place to check would be your RAM to see if it is going faulty - bad sectors on RAM make having a fully stable system running any OS almost impossible. You can check your RAM's health by running memtest86+ from the GRUB boot menu. –  Christopher Kyle Horton Jun 2 '12 at 19:12
    
Tes you memory modules. You can do from grub, executing MemTest. It will take a lot of time, but probably this is the source of the problem. –  Luca Jun 5 '12 at 19:31
    
if evrything was ok while he was using 11.10 then bad memory modules are less possible to be a cause of his problem. –  Alen Jul 1 '12 at 21:34
