Designers of repairable critical systems and associated peripherals, and quite cognizant of the 2nd law of thermodynamics, will determine and declare an approximate lifespan of their product. They have labeled it 'mean time between failure' (MTBF) with the value of time (typically in hours). As a USAF technician, and later as an aerospace engineer, it was 'the rule' to document/monitor and perform maintenance or component replacement after a system had been operational for 'x' number of hours.
In conclusion (and in 'general'), the simple fact is : if a part has been designed to operate for 'x' number of hours, it is going to be around longer if it is 'turned off' periodically.

Thanks for all your replies everyone. As there were no really strong views either way, and there seem to be pros and cons with both shutting down overnight or putting into sleep - I think I'll carry on doing what I'm doing; ie. shutting down fully at night.
Thanks for your very comprehensive reply, iko22.
I wouldn't have considered components such as power supplies, etc. I have an Acer Aspire (model no. M3910) desktop pc, approx. 5 years old. Should I be considering upgrading the power supply now, or is the original one that Acer fitted OK? Or should I just upgrade to a quality PSU if and when the PSU I have now fails?
I don't know what is inside the Acer M3910, to be honest. I'd assume that it contains a simple generic 250W supply. You'd have to open the computer case to find out. Computer Manufacturers usually use these to keep the costs down. If I'm right then I'd look at replacing it right away with a suitable 80 PLUS certified supply, in order to give your components the most protection. Make sure the one you are buying contains OCP (Over Current Protection), OVP (Over Voltage Protection), UVP (Under Voltage Protection) and SCP (Short Circuit Protection).
Hope that helps.
Always shut down when the computer isn't going to be used ! Use a ssd to quicken boot and shutdown and enjoy lower energy costs, less heat and less strain on the PSU. Mobo, hard drives......on and on.
Thanks to all for your replies. As always, really appreciated.
If I do replace the power supply, are there any recommended brands or suppliers?
