Why: Why Computer Crashes - Part 1


why computer crashes
You are looking for a true reason why computer crashes because you have become frustrated with your freeze computer and want an effective solution which can speed up your PC and prevent your PC from being crash. You know every issue can be fixed out but with a proper and right method.

Before going towards the primary concept, I would like to tell that there are several factors why a technical system freeze, the main and core reason behind is the negligence and carelessness you do with your device. Mentioned concerns and factors are going to help you to keep your PC secure it from being facing continuous errors.

You might be facing this one??

Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."
You have just been struck by the Blue Screen of Death. Anyone who uses Microsoft Windows will be familiar with this. What can you do? Most significantly, how can you avoid it happening?




01. HARDWARE CONFLICT: 


The biggest reason why computer crashes is due to components issue. Each components system conveys to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, 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 set up effectively, two of them may end up giving the same IRQ number. When the individual tries to use both devices as well, a crash can occur. The way to examine if your PC has a components issue is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.

Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).



02. BAD RAMS: 


RAM (random-access memory) problems might carry on the blue display of loss of life with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem that is sometime the ultimate question: "Why Computer Crashes?". Sometimes it may mean a part is broken and will need changing or replacement.

But a fatal error caused by RAM might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) RAM with 60ns RAM will usually force the computer to run the RAM at the slower speed. This will often crash it if the RAM is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the RAM. This can make it more stable. Another way to troubleshoot a suspected RAM problem is to rearrange the RAM chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling RAM try not to touch the gold connections, as they can be easily damaged.

Parity error messages also refer to RAM. Modern RAM chips are either parity (ECC) or non-parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad RAM. This may be due to free memory problems often linked to old Dos-based programs.


03. BIOS SETTINGS:



Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.

A 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 SD-RAM has a CAS latency of 2. Setting the wrong figure can cause the RAM to lock up and freeze the computer's display.

Microsoft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).


04. HARD DISK DRIVES:



If you face that, 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. Go to

* Start-Programs-Accessories-System Tools-Disk Defragmenter

This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.

The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).

Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimization. This can be adjusted by going to

* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.
When Hard disks are too full, it will be the main cause why computer crashes? 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.
Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to

* Start-Programs-Accessories-System Tools-Scandisk

Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.


05. FATAL OE EXCEPTIONS AND VXD ERRORS:



Fatal OE exception errors and VXD errors are often caused by video card problems. 

These can often be resolved easily by reducing the resolution of the video display. Go to

* Start-Settings-Control Panel-Display-Settings

Here you should slide the screen area bar to the left. Take a look at the color settings on the left of that window. For most desktops, high color 16-bit depth is adequate.

If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to

* Start-Settings-Control Panel-System-Device Manager

Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.

If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.

The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.

Another useful way to resolve video problems is to go to

* Start-Settings-Control Panel-System-Performance-Graphics

Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).

Look up your video card's manufacturer on the internet and search for the most recent drivers for it.
