10 Reasons Why PCs Crash
The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.
A printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself. If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen.
2. Bad Ram
Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.
3. BIOS settings
Every motherboard is supplied with a range of chip set settings that are decided in the factory. If these settings are not properly set there chances that PCs wont boot up properly
4. Hard disk drives
After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze.
5. Fatal OE exceptions and VXD errors
Fatal OE exception errors and VXD errors are often caused by video card problems.
Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start.
The action of sending a document to print creates a bigger file, often called a postscript file. Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.and eventually causing a crash
A common cause of computer crash is faulty or badly-installed software.
Central processing units (CPU) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error.
10. Power supply problems
With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.
