    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).

    Many crashes are the result of the execution of a single machine instruction, but the causes of this are manifold. Typical causes are when the program counter is set to an incorrect address or a buffer overflow overwrites a portion of program code due to an earlier bug. In either case, it is quite common for the processor to attempt to execute data or random memory values. Since all data values are possible but only some values are valid instructions, this often results in an illegal instruction exception. By chance such data or random values could be valid (though unplanned) instructions. If while successfully executing such instructions the processor happens onto a branch instruction that moves the program counter back a few bytes it would simply repeat those few instructions over and over, being stuck in an endless loop. One might say that the original bug that upset the program counter "caused" the crash, but the actual fault was an illegal instruction or endless loop some time later. The art of debugging such crashes is connecting the actual cause of the crash (easily determined) with the code that set off the chain of events. This is often very far from obvious—the original bug is usually perfectly valid code from the processor's perspective.

    On earlier personal computers, it was actually possible to cause hardware damage through trying to write to hardware addresses outside of the system's main memory. Occasionally, execution of arbitrary data on a system will result in a breakup of screen display. This is widely considered a severe system crash.

    Another cause of crashes is a race condition in communication between processes. One process may send a signal to a second process then stop execution until it receives a response. If the second process is busy the signal will be forced to wait until the process can get to it. However, if the second process was busy sending a signal to the first process then both processes would wait forever for the other to respond to signals and never see the other’s signal. If the processes are uninterruptible they will hang and have to be shut down. If at least one of the processes is a critical kernel process the whole system may crash and have to be restarted

    Apparently it crashes if you used Xanadu or Creatous Corral as the exhibits first name.

    Try renaming it after.

    When the computer crashes, it generally gives some error message. Please post the error message. If there is something like 0x0000XY (where X and Y are numbers or alphabets) post that and a better answer can be received. Also if there is any file like abcdef.dll which is involved, put that also. You can do a search using the error message to find the answer present in many forums online..

    one million) shop your working as much as date with all patches and updates and repair packs, if any, utilized 2) Use purely authorized utility or those from a straightforward source. Many loose utility incorporate advert-wares, undercover agent wares etc 3) Use a stable anti-virus utility (For Microsoft, i'll signify Microsoft protection necessities) and shop it frequently as much as date. 4) be careful at the same time as surfing 5) do not acquire and open e mail attachments from unknown people 6) do not open e mail attachment from people you already know, if do not one from them. 7) overlook approximately on line virus checker, Registry Cleaners, stay reveal screen Savers etc as all of them incorporate malicious codes related. 8) turn on your firewall. 9) shop a stable reproduction of all your useful documents on a distant not trouble-free rigidity or CD or an cyber web FTP region (zipped and password secure). documents you do not shop a reproduction is the suggestions you do not look after. study and engineer your self and discover greater skill. desire you stable success
