Output of lshw

Adding to the above all background processes continue to run such as Fetchmail,
Procmail, SpamAssassin, ClamAV and so on. I have been able to get to a log-in
screen with CTRL>ALT>ESC and log-in and do a 'sudo reboot'. My system is Ubuntu
14.04.2 LTS on a Dell OptiPlex 780 with 4Gb ram. The kernel I'm running is
3.19.0-031900-generic #201502091451 SMP Mon Feb 9 14:52:52 UTC 2015 x86_64
x86_64 x86_64 GNU/Linux. Throughout the day I see this in my syslog, not only
when the system locks-up:

Feb 22 18:00:46 localhost kernel: [ 9088.033815]
[drm:intel_crtc_cursor_set_obj] cursor off
Feb 22 18:00:46 localhost kernel: [ 9088.033821] [drm:g4x_check_srwm] SR
watermark: display plane 92, cursor 2
Feb 22 18:00:46 localhost kernel: [ 9088.033822] [drm:g4x_check_srwm]
display watermark is too large(92/63), disabling
Feb 22 18:00:46 localhost kernel: [ 9088.033824]
[drm:intel_set_memory_cxsr] memory self-refresh is disabled
Feb 22 18:00:46 localhost kernel: [ 9088.033826] [drm:g4x_update_wm]
Setting FIFO watermarks - A: plane=40, cursor=2, B: plane=2, cursor=2,
SR: plane=0, cursor=0

I'm attaching the output of the latest dmesg output, lshw and dmidecode. If I
can provide any other information please let me know.
