24/7 pc never off24/7 main switch never off and 24/7 pc never off
Is a completely different thing...
Then do you all off main switch after shutting down?
I off main switch only when I not at home for few hours or more for safety reason.Then do you all off main switch after shutting down?
In offices, many PCs are left on 24/7 for years.
Fans will usually be the first to go.
24/7 but idle and 24/7 under heavy load all the time will yield different results. Retail hardware are generally not built for 24/7 heavy usage.
Anyway if it is just left idle, there is no reason not to switch it off. It doesn't take long for a PC to boot up nowadays, so I don't see any reason to leave it on since it is just wasting precious resources. You can even set it to go to sleep mode after x number of hours, which is better than leaving it active.
Does it shorten the lifespan of your desktop?
Now I also never off main switch after shut down
IMHO.
e) Windows will have write activities in the background, use HDD as boot up device instead of SSD.
I am not sure if you have tried using Windows 10 on a mechanical drive of late. It is exactly a lot of activities hitting the drive and making the response time unbelievably slow. Perhaps I am spoiled by my SSD, but I cannot remember a mechanical drive being that slow since Windows 7. I believe a good SSD will be able to take substantial amounts of write throughout its lifetime, so I don't think it is something that we need to be concerned about.
I second this. With ssd now, how long does it take to start up? i used to keep mine on due to slow bootup to windows. Now i shut off wth SSD. It is a god sent tech progress.
1 thing for sure like what others said. Fans and the other mechanical parts like hardisk (we all know for what ya.)sure gg 2-3 years based on my 24/7 routine previously. PSU not that bad, 4-5 years average life span.
Alot of people claimed their pc lasted 4 years and beyond. My guess is probably not much usage daily.
