How many times have PCs, smartphones or tablets been “frozen”? Surely it will have happened often and for the most diverse reasons. Panicked by the malfunction, the first thing that comes to mind to do is to switch off e restart in the hope that things will be right. In fact, that’s exactly what needs to be done in most cases.
Because it really works
In the most serious cases in which it is not possible to manually restart the device, we are forced to press and hold the power button: after a few seconds, the PC or mobile phone screen turns off. At that point, after waiting at least a minute before restarting the machine, as if by magic everything is solved and the reset was successful. This method works in most cases even for much more sophisticated (and expensive) machines. A normal pc plays a lot functions at the same time: we open programs, install or uninstall software, leave the browser open for hours (perhaps with dozens of windows and as many sites) but, in addition to our direct actions, we must consider all those operations that the machine carries out “in the background” (in autonomy) to continue processing data and commands. As these are very complex devices, it is more than likely that something will get stuck every now and then.
The 3 reasons why a pc crashes
As computer experts say, there can be three main but common cause that block our device: a bug in the code of a program that leads to a loop, an overload of the RAM (the temporary memory that the computer needs to work) or a small unexpected error that unexpectedly blocks operations. In these cases, the only thing to do is to interrupt the work with the “do-it-yourself” method we talked about earlier: turn off the system and then turn it back on. But be careful: this procedure does not solve the underlying problem, it is just a way to get out of a blocking situation. “Sometimes turning an electronic device off and on again at least temporarily resolves a malfunction. Electronic devices based on microcontroller or processor are generally very complex. The complexity is such that the presence of bugs is practically unavoidable, so much so that for many there is the possibility of updating the firmware, applications or the operating system according to which devices we are talking about“, says Marco Brembati, a graduate in computer engineering at La Sapienza in Rome, who answered the question of many users on It.quora.com.
Other cases of blockage
In other cases, the effect of the on-off cycle is simply to decrease the temperature of some “distressed” components and allow them to function until they heat up again. “I would also add that in other cases, in addition to switching off, a reset to factory settings is required, as some parameters are stored in a permanent memory (FLASH or Disk) which resists switching off. This is kind of what happens when you reformat a computer or reset its BIOS“, underlines the expert. It is important to know, then, that restarting the computer is different from turning it off and on again and is defined as a” soft-reset “: it restarts the system, but it has not been completely stopped. net break to all computer components, power must be completely removed.
Many technicians recommend turning off their devices from time to time for the same reason: to allow the computer or smartphone to take a break from the many operations it has opened at the same time. Turning it off – for a few minutes – frees up RAM from pending processes and your computer, smartphone or Smart TV can become more efficient once turned on again.
