If you mean switching off without shutting-down properly - it won't destroy the hard-drive - but it may cause errors. The hard drive is a flat disc, with a sensor that reads and writes information to it. When you shut-down the computer, it moves the sensor to an unused part of the disc, and cuts the power to the disc's motor.
The hard drive saves all data on your computer and will stay saved after the computer shuts down. RAM will temporally store data but will be deleted after shut down.
turning the computer off
no you are shutting the coumpter down whats the point?
Yes, it should stop all shutting down actions by your computer if the system is overheating.
Have you tried shutting down all programs, then shutting down and re-starting your computer ?
No.
many reasons but just scan your computer to be on the safeside
You have a virus. Or it is continuously overheating?
Using the "start" button to shut down your computer gives your system a "heads up", if you will, that you are shutting it down. Shutting a computer down abruptly could be destructive to the system if you shut it down in the middle of an important process.
It depends on the type of information. Data saved to the hard drive or solid-state drive will remain intact after the computer is turned off. However, information stored in temporary memory (like RAM) will be lost when the computer is powered down. Always save your work before shutting down to avoid losing any unsaved changes.
When my computer would unexpectedly shut down on its own it turned out that the processor fan was bad and the computer was shutting down due to the processor overheating.
Re-booting your computer will refresh everything without shutting it down completely.
