I, too, agree that this might be a problem with the processor
overheating. If your motherboard reports temperatures over ACPI, you can
obtain the current temperature like this:
cat /proc/acpi/thermal_zone/THM/temperature
If you want to see if this is a real problem, try doing the following in
at a prompt: (it's one line)
while (true) do cat /proc/acpi/thermal_zone/THM/temperature >>
~/temp.log; sleep 20; done
Leave the terminal open and use the computer as normal, and when it
crashes, check ~/temp.log to see if it shows too high a temperature. If
it does, you might have to check if your fans are working/covered with
dust/blocked.
The blinking lights signify a kernel panic. A likely source of the
kernel panic is a fault in the wireless driver. Is your kernel image up
to date? Could you try removing the iwl3945 module and using just wired
ethernet for a while just to see if that's the problem?
sudo rmmod iwl3945
