maybe memory is overclocked? Try to test your memory with memtester
from a desktop session. This helps me to find the issue in memory.

Public bug reported:
I have randomly system freezes on Ubuntu 12.10 64 bit since I installed my
system on a new blank ultrabook (Wortmann Terra Mobile 1450 II) in December
2012.
When the system freezes no mouse , no keyboard, no REISUB is possible. The
screen is corrupted and did not update.
I have already tried the following 3.8er kernels in the past:
3.8.0
3.8.0-rc3
3.8.0-rc4
3.8.0-rc5
3.8.0-rc7
3.8.0-944_drm-intel-nightly-2013-02-15
But I had no luck. All show the same behavior. That was the reason why I
continued with the official version 3.5.0-25.
But from now I will again work
I installed 3.8.1 now. I will report it if the situation improves.
