Open the box again and check the cpu heat sink. If it is not getting very warm, it could be loose or poorly sealed with thermal material. That could make for intermittent heating problems. You might have to remove and remount the heat sink.
I don't see anything to give me any definite clues.
But here are a couple of questions that might yield a clue:
Has this machine sat unused and not plugged in for any
length of time (could be the CMOS battery is dead/dieing)?
I bought it in January and used it every day since then. When it
was a windows box, I would have it running for several days at a
time doing my usenet harvesting.
When the machine is locked up, can you do Ctrl-Alt-F2 and
get a console (Ctrl-Alt-F7 to get back to the GUI)?
I can't do anything with it. I can't get to a console. I can ping
it when it's working normally, but when it locks up it doesn't
respond to pings or anything else. When it locks up it stops
everything. If I'm watching a movie on it when it locks up, the
audio stops and the last frame is on the screen until I push the
power button long enough for the machine to turn it off. I have it
and the other box plugged into a netgear router. There's a light on
the front of it for each computer that's plugged into it. When I
download using this machine, it's light on the router blinks. When
the machine locks up, it's light stops blinking.
Also I opened it up and checked for dust bunnies. There was a
little dust, but not enough to cause any problems. Today I opened a
terminal and sensors -f. I get results that vary between 40 and
60F. I do believe I'm not getting an accurate reading because it's
not that old in here. Also I shut the machine down and checked the
heat sink for the processor. It wasn't even warm.
What, exactly, do you mean by "locking up"? More
specifically, can you be sure that the machine is locked up or
could it just be the display? One way to test that theory is
to ssh into the machine from another machine and run some
application that does updates like top or htop, or a looping
script displaying the time every few seconds. If the machine
seems to lock up but the remote machine still shows ongoing
changes, then it is not the whole machine locking up.
I have an HP Pavillion p6-2003w pc. This tinyurl http://tinyurl.com/b36tanr takes you to
a page at HP that will give you details about what's in it if
the following isn't enough.
The problem is that it's been freezing at random. It was
really bad on Kubuntu 12.0.4 64 bit. It was like the bad old
windows 3.1 days. I never knew when it would lock up.
Sometimes it would run all night without any problems. Other
times it would lock up a few minutes after I rebooted it the
last time it locked up. Sometimes the image on the monitor
would just freeze. Other times the monitor would go to a
background of either blue or gray with thin vertical lilnes.
I upgraded to Kubuntu 12.10 64 bit and it was a little more
reliable. Once it locked up and when I rebooted it, the sound
card no longer worked.
Is there some bug with this machine? Is there some problem
with ubuntu? I'm wondering because last year my other
computer behaved similarly. I posted the problem to this list
and someone told me my problem was a defective nvidia card.
They made a bunch of chips that didn't get along with
something in windows versions after xp and versions of ubuntu
after, I believe 8.04.
