Why Did My Computer Fail?

Chances are it was your operating system failing due to any number of reasons.

These are just a FEW of the variety of reasons why operating systems fail. 

Power Related problems: Improper functioning of the System Power Supply can lead to immediate shutting down of the System.


Overheating of RAM: Overheating RAM could lead to corruption of data in it. This can lead to definite crash where reset is a must.


Improper Overclocking: Causes Overheating. Certain Hardware Components are sensitive to heat. When Overheating occurs automatically the system shuts down.


Bad Sectors in Hard Drive: The Hard disk is divided into sectors where data is stored. Some sectors become Bad sectors. Reasons: 1. Prolonged usage - many writes and reads. 2. Manufacturing defect. If sectors in the hard disk, where important system information is stored, becomes a bad sector then it is difficult to load those files, thus leading to a crash.


RAM Issues: Cause: Data retrieval not possible. This is very important as this leads to Fatal Exception Error.


Major Misconception: An application crash in your system does not always lead to a system crash. Generally "Nothing" happens to the OS. It just sends you a report saying so and so application has crashed.

Any OS crash (MAC & Windows) can occur due to either of the two main reasons:

1.      Hardware Problem.

2.      Software Problem.



Corrupt Registry: Before starting any application, the OS looks into its registry. Registry is a small Database where all the information about kernel, drivers and information about applications are stored. Registry can get corrupted due to improper uninstallation of applications, careless editing of registry, too many installed applications etc.  This leads to routine applications refusing to start thus causing the Blue Screen of Death to be displayed.

Improper Drivers: In order to use additional hardware, we need drivers, generally downloaded from the internet. These drivers might contain bugs. These bugs cause the OS to crash. Modern operating systems are released with the option of "Safe Mode Boot". Safe Mode Boot loads only important drivers (minimum). Safe Mode Boot is used for diagnostic purposes to find the driver with bugs.

Virus and Trojan: Common reasons for OS crash. Viruses and Trojans corrupt the system files, "eat up" the memory not allowing OS to retrieve it when a programs stops, changes administrative settings, frequent rebooting without any sign etc.

Thrashing: Deadlock occurs when two programs running require control over a particular resource. Sometimes during a deadlock, the OS tries to switch back and forth between the two programs. This eventually leads to Thrashing where the hard drive is being overworked by moving information between the system memory and virtual memory excessively causing a system crash.
