Things You Must Know To Avoid PC Crash Part 2

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. 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 optimisation. This can be adjusted by going to
* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.
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.
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.
5 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 colour settings on the left of that window. For most desktops, high colour 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.
6 Viruses
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. This is why it is a good idea to create a Windows start-up disk. Go to
* Start-Settings-Control Panel-Add/Remove Programs
Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.
A virus scanner requires a list of virus signatures in order to be 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.
An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Norton AntiVirus 2000, made by Symantec ( www.symantec.com).

Improve performance by defragmenting your hard disk


Fragmentation makes your hard disk do extra work that can slow down your computer. Removable storage devices such as USB flash drives can also become fragmented. Disk Defragmenter rearranges fragmented data so your disks and drives can work more efficiently. Disk Defragmenter runs on a schedule, but you can also analyze and defragment your disks and drives manually. To do this, follow these steps:

  1. ?id=microsoft.windows.resources.shellexecutetopiciconClick to open Disk Defragmenter.

  2. Under Current status, select the disk you want to defragment.

  3. To determine if the disk needs to be defragmented or not, click Analyze disk. ?id=18abb370-ac1e-4b6b-b663-e028a75bf05b If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

    Once Windows is finished analyzing the disk, you can check the percentage of fragmentation on the disk in the Last Run column. If the number is above 10%, you should defragment the disk.

  4. Click Defragment disk. ?id=18abb370-ac1e-4b6b-b663-e028a75bf05b If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process.
Notes

  • If the disk is already in exclusive use by another program, or if the disk is formatted using a file system other than NTFS file system, FAT, or FAT32, it can't be defragmented.

  • Network locations can't be defragmented.

  • If a disk that you're expecting to see under Current status is not showing up there, it might be because it contains an error. You should try to repair the disk first, then return to Disk Defragmenter to try again. See Check your hard disk for errors for more information.

Maintain Your Hard Drive.


I completely agree on defragmentation being an oft forgotten or neglected job. A lot of users defragment only when the system has already slowed down and they check the HDD and find it running out of free space and very badly fragmented. It takes much longer to defragment infrequently than regular defrags keeping things smooth and short. In fact there are programs which can be set to defragment very efficiently automatically which need no inputs whatsoever.

Why Disk Fragments a problem?

Any storage action on the magnetic disk like creating, deleting, moving, updating and copying files will lead to fragmentation and consequent performance loss. As time goes by, this accumulation of fragments on your hard disk becomes bigger and bigger. As the hard disk reads and merges these separate fragments every time you open a file, they will eventually cause problems such as system slowdowns, PC crashes, slow startup and shutdown, and will even shorten the life span of your hard drive. That is why defragmentation is so important for your entire computer system.



Advanced Defrag – The better and easier defrag solution!

You may find various defrag programs in the market, they may look the same, but many of them lack of ability to
effectively defrag all the MFT (Master File Table), they will automatically skip certain system files with extensions
such as DLL, INI, COM etc during the defragment thus left remnant fragments after each defragment action, it can
also easily get halted while defragging which is very user-unfriendly.


Advanced Defrag rectified all the cons above from these defragmenters, and the efficiency is even better. Its advanced
defragment arithmetic not only enables you to fast defrag, but also defrag completely and thoroughly. If you would
like to give your PC hard disk a completely care and experience the most efficient defrag technology, Advanced
Defrag is the perfect choice for you.



How it works?

Your hard disk controls a magnetic head which searches the areas where the parts of the required file are located,
reads the data and transfers these fragments to the disk cache or EMS memory. The time this takes is called the
average seek time. The average seek time of most hard drives is less than 9.5 millisecond. The Advanced Defrag
program is able to collect the various fragments of each file and store them very quickly into contiguous space on
the hard disk which greatly reduces the seek time of the magnetic head. Better file reading and writing speed is
provided as a result. It does make a difference if you have got used to work and play with a fast and smooth system.
It also helps to prevent premature hard drive problems and retrieve the data in the event of a drive crash.
