If you're up for it, I'd replace the heatsink compound between the processor and the heatsink.
Often on older machines, the compound dries up and ceases to be effective in transferring heat away from the chip. This causes the chip to overheat and KP. Very common in older machines, both processors and graphics chips.
Definitely check the heat sink compound. A little tube of arctic silver is a lot cheaper than a mini.
A few years ago, an MDD that I bought to trouble-shoot/replace my MDD began locking up hard after about 15 minutes of use. I was going to replace the logic board, but in the process of removing the heat sink, I discovered that the layer of heat sink compound had become something akin to the floor of Death Valley. If that doesn't solve the problem, it might be time to start looking for deals on Minis.
Yep, I'd check into this too. My QS 933 displayed the same sort of symptoms which I pegged to bad memory but when the shop opened it up it turned out that the fan was totally fouled with cat hair. Obviously, this led to the machine overheating.
