What do we actually mean by System Crash?

Question

and how does system crash happen and is there any way repair the Operating system after that.

Answer 1

System crash normally because the OS can't run the necessary files due to virus, missing files, incompatible hardware or software and so on. To repair it, you need to find out the root problem first before doing something. What I do before I do something "big", I will create backup so if there's something wrong, I just restore form backup file

Answer 2

A system crash can mean any number of things, and it can also be caused by many different factors.



Probably the most common is when your computer just locks up, forcing you to reboot using the power/reset button. This is often known as the computer "crashing". This usually happens when too many applications are running at the same time; a collision of bits happens within the processor and the computer ceases to continue operating.



More serious "crashes" (as in, when the computer won't switch back on properly) can be caused by corruptions in the core operating system files. In windows, this often leads to a BSoD (Blue Screen of Death), in which an error code is given. The operating system can be corrupted by viruses, bugs in programs, or just the user modifying/deleting files that are required, such as elements in the Windows Registry.



Another factor that can cause a BSoD is the CPU overheating. This is more of a hardware problem, as the CPU either has dried thermal paste, or the heatsink is not properly attached.



If a computer fails to start after crashing, most Operating Systems have a "Safe Mode", which can be accessed by pressing certain function keys when the computer is booting, (usually F10). In safe mode, the operating system only loads the necessary drivers and files, therefore any viruses or programs affecting the operating system will not start. This allows the user to remove anything stopping the computer from functioning properly.



If, in Windows, the operating system has become corrupted, a Windows repair disc, with recovery console (downloadable from the microsoft website) can be used to restore any files that have been broken. The operating system should then boot up fine.

Answer 3

from what ive experienced some people say system crash, when in fact the system is just 'hanging' because of something preventing it from shutting down (usually anti virus), when the whole thing freezes up randomly, or when it does actually 'crash' with the whole blue-screen-of-death thing which is caused by a whole load of things like, dll files being missing or corrupt, viruses screwing around, etc or because your hard drive is screwed and is having problems finding certain files (usually important ones).



if you need to repair the operating system, then you need to have the OS master disk. some retailers give the master disk with the computer some dont. dont use the manufactorers disk though.



if you have the master disk, then just boot from disk, choose the language you want to install windows in, then click next. on that page it will have an option to repair windows. click on that and then click past the next page, and the click repair.



that should replace the missing files or any corrupted files.

if you dont have that disk, microsoft should be able to send you it out, or if you google it, you'll more than likely be able to find the repair only version of it for download (for vista you can anyway)



other than that, computers can crash simply because the motherboard is screwed, the fan isnt working therefore its overheating, corrupted usb drivers, power failure, power surges..........the list goes on and laptops are more suspectable to full out crashes too.

Answer 4

Generally any time something happens that renders the computer unusable, we call it a system crash. And 99.9% of all system crashes are resolved with a reboot.



Repairing the operating system could be as simple as a reboot (see above), reinstallation (for a file corruption error) to major surgury (for a hard disk failure).



Do you have more details?

Answer 5

A crash in computing is a condition where a program (either an application or part of the operating system) stops performing its expected function and also stops responding to other parts of the system. Often the offending program may simply appear to freeze. If this program is a critical part of the operating system kernel the entire computer may crash (a system crash).

Answer 6

If this ever happens, which i pretty doubt that it's going to ensue to u because of the fact basically some a million who by no potential used a working laptop or computing gadget ought to crash that computing gadget by potential of no longer understand what he/she is doing. anyhow if have been to ensue.... whilst the computing gadget is booting up, consistently press the F8 button on your keyboard and choose the 1st decision "risk-free Mode" and then do a device fix there.

Answer 7

Depends on how much damage it's done. There are programs you can buy to try and restore your system.



If your computer still runs, go to Start--->All Programs--->Accessories--->Tools---->System Restore---->pick a date
