The ones that normally go are the electrolytic types .. aluminium cans
with black(usually) printing. The electrolyte is a liquid and tends to
dry out over a number of years use in a warm environment. Swelling,
(usually of the flat top), discolouration, oozing electrolyte.
The next most likely candidates are tantalum capacitors, which tend to
be little black rectangular block. When they fail, they tend to blow a
corner off of the moulding, or sometimes just a small hole/crater.
Most of the rest will be ceramics, which are usually trouble-free.
Gordon.
So I've had a look at the capacitors, and I can't see any that look
broken. I've also done some more investigation and found the following:
if the computer locks up and I then run memtest on reboot it finds
errors in the same memory locations each time. However if I reboot
cleanly it doesn't find errors. The fact it finds them in the same
locations would indicate to me that it's a memory problem. However, I
also ran the mprime torture test, and that failed on both the memory
intensive test, and the test that doesn't use much memory. Which would
tend to indicate that it's not a memory problem.
I'm now trying a kernel parameter that should stop it using the "bad"
memory to see if that fixes it...

Hi Leo
If your memory is on more than one card, try removing them one at a time
and booting up. That's how I identified the dud memory in my PC.
But I expect you've already tried that. :)
