Hello, All!
I am running Linux 3.4.11-2.16-desktop x86_64, openSUSE 12.2 (x86_64), KDE: 4.8.5 (4.8.5) "release 2" on a desktop rig. Very intermittently and unpredictably, the screen will go black. Sometimes it freezes the image, or cease sending signals to the monitor, but these last two are more rare. In all cases the mouse and keyboard are unresponsive, eg cant' even toggle "NUM LOCK" on/off.
I have not found the cause, and think it may involve the GPU since it has been running hotter and hotter over the past couple months. Although when I run diagnostics through windows 7 dual boot no errors are found, either with ATI's software or OCCT. Sometime the problem will occur twice in a day or twice per month. Have only had a couple of crashes on windows in same time frame, but openSUSE is my primary OS.
The last couple times have occurred while streaming either audio or video (with sound) via firefox, but this is not always the case. I have disabled all desktop effects to no avail. I would greatly appreciate help in either diagnosing the problem or ruling out the OS, suggesting hardware malfunction. I have read a couple of similar posts w/ these symptoms, but the issue does not appear to be the same.
I should be running the "RADEON" driver, which was doing better than "fglrx" before the lock ups started.
The last freeze occurred around Feb 6 10:33 on the system clock, so I've only included around that time in the var/log/messages
Hardware info:
SUSE Paste /var/log/messages:
SUSE Paste Xorg.0.log:

SUSE PasteSUSE Paste (CAN'T POST REST OF MMCHECK RESULTS NOW, APPARENTLY "I AM SPAMMER!")
PS: The CPU *may* be overclocked ~16%, but it has not failed a single stability test in years. ;) The GPU is tuned using ATI software recommendations, with fan set to run at 100% all the time.
