According to my source, he claims that it does but I thought I'd ask since I assume a dying hard drive and a computer's motherboard are separate issue.
The motherboard has no moving parts, but the electronic components (chips) do generate heat. As long as the system has a resonable airflow, the components are designed to withstand temperature changes.
Most chips don't really heat up much and the ones that do, CPU, North Bridge, GPU, etc., they had been designed to withstand wide temperature ranges. For example, here are the temperature ranges for my system:
The ambient temperature was around 20-22 degree Celsius. Note that the temperature for the internal hard drive is pretty close to the ambient temperature, while the external drive is running much warmer.
The CPU and the GPU on the other hand are 4-8 degree Celsius above ambient temperature, which isn't that bad. Playing some games and/or heavy use of the computer can easily push the temperature for the CPU and GPU to the 50's range, which is about 50% more than the idle temperatures.
If it's true that turning on/off the computer would damage the motherboard, using it beyond idling would downright destroy it in a very short timeframe. I for one who has some doubts that it's true...
You are correct that the HDD and motherboard is a separate issue. One the other hand, the power supply could cause damage to the HDD, even if there's no storm in your area...
