I'd go along with that. 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...
