I installed 64 bit Ubuntu 12.10 recently on a freshly formatted hard drive. My problem is that whenever I open a program like Firefox or Thunderbird there's a pause and then my screen goes black for a second and it logs me out.

The software center works and I can access terminal just not programs. My specs are 8 GB DDR3 RAM, i5 3570k CPU, NVIDIA gtx 670 graphics card and a 650 GB hard drive.

I can run 32 bit version of Ubuntu without problems.

Any ideas? edit: steam also crashes when it opens up, I can log into but when it actually opens up it crashes as well. thevwirdest thing is that ive reinstalled ubuntu like 4 times now, samething everytime. I'm installing it from USB though. also tried re downloading it to USB multiple times. and I tried going into the live USB THEN installing as well as installing from the menu.

Have you installed any graphics drivers? – Seth Feb 18 '13 at 2:03
Yes but the problem happened before and after, and I'm talking directly after a fresh install, still crashes. – user133073 Feb 18 '13 at 3:04
Odd thing is that the Software Center runs! Is your problem only with Firefox and Thunderbird? Which are all the programs that cause a log out and those that don't? Please edit your question with the information. – user25656 Feb 18 '13 at 3:54
