How to Check the Health of your Hard Drive

Hard disk failure is possibly the worst thing that can happen to your computer and it often occurs without giving any warning signs.

Test Your Hard Drive for Impending Problems

hard diskYou may however run certain tests on your computer beforehand to get an idea about the current condition of your hard disk. This should in turn help you decide whether a replacement drive is necessary or not.

Step 1: Check your hard disk for errors

All recent versions of Windows include a utility called Chkdsk.exe that can check your hard disk for any bad sectors.

You may either run Chkdsk from the command line (see details) or launch Windows Explorer, right click the drive that you wish to examine and choose Properties. Switch to the Tools tab and click the “Check Now” button under Error checking. Select “Scan for and attempt recovery of bad sectors” to perform a thorough disk check.

Step 2: Understand the sounds of your disk

Do you sometimes hear strange sounds coming out of the CPU box? Well, if the hard drive is making those sounds, it could be an alarming situation and your best bet would be that you turn off the computer before any further damage is done to the disk.

But how do you distinguish between sounds coming from a hard disk with noise that’s made by the fans or the power supply? Here's a useful page where you can listen to recorded sounds of various hard drives that have lead to a crash. If your disk is making a similar sound, get a replacement quickly.

Step 3: Catch errors before they happen

Disk Checkup is a free hard disk monitoring utility that displays tons of diagnostic data about your disk. While the level of detail it provides may easily confuse even tech-savvy users, just ignore the numbers and keep the utility running in the background.

It monitors your disk’s temperature, read and write error rate, etc. and will alert you when the values of any of these parameters approach dangerous levels. These may be signs of an impending disk failure. Disk Checkup is free for personal use.

Step 4: Thoroughly test your Hard Disk

SeaTools is free diagnostic tool that can completely test your hard drive regardless of the OS installed on it. The tool is provided by Seagate but it works with non-Seagate  disk drives as well.

To get started, you need to download the ISO image of SeaTools for DOS and create a bootable CD. Now boot the computer with the CD in the drive, accept the license agreement and run a long test (the full scan). If any defects are found, a list will be offered at the end or after aborting the disk scan.

Other computer vendors /disk manufactures including Samsung, Hitachi, Toshiba (Fujitsu), Western Digital, Lenovo, Dell, etc.  too offer diagnostic tools that work only with their own brand of hard drives. If you are having frequent computer problems (like system hangs or fails to boot up), you may run these tools to confirm if the problems are hard drive related.

Important: While these tools can help you diagnose your hard drive's health, they are still no good substitute for regular backups.

How to Troubleshoot a Stop 0xC0000218 Error Message

A Stop 0xc0000218 error message means that a necessary registry hive file could not be loaded. This error message can occur if the file is corrupt or missing. To resolve this issue, you can reinstall the operating system and restore the registry files from a backup. The registry files may have been corrupted because of hard disk corruption or some other hardware problem.

This error message can also occur if the driver has corrupted the registry data while loading into memory, or the memory where the registry is loading has a parity error. In the latter case, turn off the external cache and check the memory chips. 

To resolve this issue, follow these steps:
 
-Start your computer by running the Recovery Console, run the chkdsk /p command on the drive, and then restart your computer. -Test to determine whether the issue is resolved. If the issue is resolved, do not complete the remaining steps. If the issue is not resolved, go to step 2.
 -When Windows loads, press SPACE BAR when the "Load Last Known Good" message appears.
    Complete a parallel installation, and restore the registry files from a tape backup. To do so:
       - Reinstall Windows in a separate folder.
       - Restore the damaged registry hive from backup. This procedure is specific to the backup application that you used to make a backup. Consult the documentation of your backup application or consult the vendor if you need assistance. Typically, this procedure requires you to restore a system state backup to an alternate location, and then copy the appropriate registry files to the %SYSTEMROOT%\System32\config folder of the damaged operating system.
        If you do not have a tape backup, include the backup of network servers and production workstations.
    NOTE: If Windows is stored on a FAT partition, you can restore the files by using another computer and by copying the registry hive files to the %SYSTEMROOT%\System32\Config subfolder.
If the Stop error message was caused by a hardware problem (for example, bad sectors on the hard drive), the drive may require a low-level format, repartition, reformat, and a restore of the entire system from a tape backup to clear up the problem. Although this would be the most drastic case, if the Stop error message was caused by a physically bad sector, the sector must be relocated with a low-level format.

WJView Error on Start Up

Wjview lets you view window-based Java applications. A possible cause of the error message is if Wjview attempts to start an application on your system that no longer exists. To check this, perform the following steps:
1. Start Msconfig.
2. Select the Startup tab.
3. Scan the list for any entries that contain "wjview."
4. If you find any "wjview" entries, try disabling the Wjview startup
component and locate any associated folders identified in Msconfig that you
might need to delete to determine whether that solves the problem.
To delete the "wjview" entries rather than disabling them (and to check
under non-XP OSs), perform the following steps:
1. Open a registy editor (e.g., regedit.exe).
2. Navigate to the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run
and
HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Run registry
subkeys.
3. Remove the invalid "wjview" entries.

Note you can save the registry key first by:
On the File menu, click Export.
In the File name box, type SaveKey, and then click Save.
Or create a system restore point prior to editing.
Note: If the registry key is not there, you can simply create one by going
edit > new.

How to Fix DLL Errors

What is a rundll error?

Rundll.exe files are systems process directly related to your computer's Windows Registry. All Dll files are a part of vast library that contains code and data that is shared by many programs. This helps to produce speed and memory efficiency in your operating system by reusing the same code or file to run many functions by various programs. An error occurs when program aren't allowed to access this code.

Why do you have Rundll Errors?

Windows uses rundll files to load programs, files and applications. If the dll file is missing or corrupted, any application using that file cannot be loaded. This will produce a rundll error. The reason why the file has gone missing is often linked to spyware or a virus. This kind of malware often tries to hijack the files being shared by the rundll file. The other programs sharing the file then do not operate efficiently or wont load at all.

 

- Reinstall The Program

In some instances, DLL errors are a result of a problem with an individual program. Generally, you can pinpoint the program that's causing the error because when you try to use the program, the DLL error pops up.

For example, if you're receiving DLL errors every time you try to run Microsoft Word, you're almost certainly dealing with a problem with Word. Reinstall the program then head to the software manufacturer's Web site to search for program patches or updates.

Often reinstalling the program does the trick because when you reinstall the program, you're also reinstalling the DLL file.
    

-Run Your System Restore Utility

The system restore function is often a lifesaver, especially when it comes to dealing with DLL errors. Initiate a system restore, making sure the restore date is prior to when the DLL error occurred. A system restore should correct the DLL error.

Unfortunately, however, there will be times when a DLL file will make it impossible for you to get Windows running normally. Should that be the case, start your computer in safe mode then run the system restore.

-Run a System Virus Scan

If you have an anti-virus program – like Norton Anti-Virus or McAfee – run it. If you don't, get one as soon as possible , and run it on a regular basis.

Often, you can find the source of your DLL problems with a simple scan. It's common for DLL errors to occur as a result of spyware and viruses. Anti-virus programs will locate and eliminate problems, which should fix your DLL error.

 -Check For Updates & Download Them

Sometimes DLL errors occur when you install a new program. For example, you might download FrontPage and start receiving DLL errors. When that happens, head to Microsoft's Web site and look for any program updates. If there are updates, download them.

If you don't find any program updates and patches, you should uninstall the program. It's likely the DLL error will go away when you uninstall the program.

Still, you'll have to deal with the problem of not being able to run the program properly on your computer. To help solve that problem, contact the software manufacturer's technical support.
    Search Online For a Solution

Every computer user has to deal with DLL errors, so you're not alone. In fact, some computer experts recommend searching online for the answer to your DLL problems.

For example, you may be getting a DLL error telling you a particular DLL file is missing. In that case, head to your favorite search engine and search for a download of the missing DLL file.

If you're getting a WMPDXM.DLL error, go to Google and search for "WMPDXM.DLL download." Oftentimes, you'll receive dozens of hits. Choose a site then download the DLL file, and your problem should be solved.

Ultimately, while DLL errors can be annoying and time-consuming, there are numerous simple ways you can fix the problems. The key is understanding what you need to do and taking that action to ensure your computer begins to run smoothly again.

How To: Delete Un-Deletable “Access Denied” Files or Folders in Windows

Windows98/200/ME

 Many times when trying to remove an unwanted program, especially a piece of adware or spyware, you may run across a file that is undeletable by any normal method. When you try to remove it you'll receive the error message shown below telling you "access denied" and explaining the file may be in use. You may also receive one of the following messages.

-Cannot delete file: Access is denied
-There has been a sharing violation.
-The source or destination file may be in use.
-The file is in use by another program or user.
-write-protected and that the file is not currently in use.

the easiest way to remove an undeleteable file is to boot to a DOS prompt and manually delete the file. Before you do this, you'll want to make a note of the location of the file including the entire path to it. Follow the steps below to delete these types of files.


  -Click on Start, Find, Files and Folders
  -Type the name of the undeletable file in the Named or Search For  box
   - Make sure the Look In box shows the correct drive letter
    -Click on Find Now or Search Now and let the computer find the file
    -Once the file is located, right-click on it and choose properties, make a note of the file location. Usually this is something similar to

    c:\windows\system32\undeleteablefilesname.exe

   - Close the search box
    -Locate a boot disk for your version of Windows, if you do not have a boot disk, follow the steps on the link below to create an emergency boot disk.

How To Fix Rundll32.exe Errors

The reasons behind rundll errors are numerous and intriguing. Where do they come from? What are they? How do I get rid of them? These are all very good questions to ask. Unfortunately, no simple answers exist.

Rundll errors can originate from a number of sources including viruses, buggy software, spyware, or drive errors. A faulty installation, one that has not been completed or did not install properly, can also be at the root of the problem. Moreover, an uninstall of a program that has been performed incorrectly or incompletely may also be the cause of rundll errors. Additionally, undetected spyware may be responsible for the rundll errors occurring on your computer.

A rundll32 error is often caused when Windows attempts to load a file but is unable to do so. A message indicating that a rundll error has occurred usually appears on the computer screen. Whenever Windows cannot load a file because it cannot locate it, a rundll error has occurred.

In order to solve the problem, it is often necessary to go through a series of possible solutions or fixes to the problem. The first and most basic step is to do a simple reboot of your computer. If this does not seem to solve the problem, continue to the next possible fix.

If the rundll error has occurred because of a faulty uninstall, the next thing to do is to completely redo the uninstall. How do you know if this is the problem? Actually, you don't, but you can consider it, if you recently attempted to uninstall a program. To uninstall the program again, you will first need to reinstall it. Now, carefully perform a new uninstall of the program. If this solves the problem, you are in the clear. If not, continue troubleshooting.

If you have an up to date anti-spyware application, run it now. Since spyware, adware, and malware are constantly evolving into newer and more insidious versions, it is extremely important to maintain a current version. If the rundll errors continue to occur, attempt to do a clean boot.

 

 

Complete the following steps in order to perform a clean boot on your computer.

  -  Click start to open the menu.
  -  Click run.
  -  Type 'msconfig' in the input field.
  -  Click ok. The System Configuration Utility should open.
    Once the System Configuration Utility opens, choose the selective startup option by clicking in the small circle in front of it. Deselect all but one choice listed below it. It doesn't matter which one, because you will need to do this until you have covered each one of the choices.
    -Click ok.
   - Reboot your computer.
    Once this process identifies the item that is at the root of the rundll problem, you move to the next step. Select the tab at the top of the System Configuration Utility Window that corresponds to the item that has been identified.
   - Deselect all but one of the choices below the tab.
    -Reboot your computer. If the computer reboots without any problems, continue the process of elimination. Deselect different scenarios until you identify the problem. Reboot.
    Once you identify the problematic item, you are finished with this procedure

Install Memory RAM

This guide will take you through the process of performing a RAM upgrade.

This section refers to installing DIMM memory modules into your computer, step by step with the aid of photos.

To install your memory you will need:

    Compatible DIMM memory module/s.
    Cross-point (Philips) Screwdriver suitable for your PC case.
    Anti-Static Wrist-strap

Locating the DIMM slots

 
After removing the cover, the first thing to do is to locate the DIMM slots on your motherboard. fig. below gives you an idea of what you are looking for

Unless you are installing a new motherboard, then your slots will already have at least one dimm module installed. If this is the case, then install the new memory module into the empty slot next to the module that is already installed.

If your motherboard does not have any memory installed, then refer to your motherboard's manual for details about which slot to use.

note: Motherboards vary, although there are three slots in our example, your motherboard may have a different amount of slots

 

Install your new module(s.

• Take your module out of its anti-static bag and hold it by the edges.
• If you have more than one open slot, fill the lowest numbered slot first. If you can't see any numbers on your motherboard, use the slot that is closest to the filled slot(s).
• Line up the notches in the row of gold pins at the bottom of your module with the keys in the DIMM slot on your motherboard. (If the notches don't line up right away, flip your module around and try it the other way. It doesn't matter which side of your module has the black chips or the stickers on it. The important thing is to line up the notches.)

• Use your thumbs to press the module into the slot. Press hard! It takes about 20 pounds of pressure to get the module properly inserted in the slot. This may mean you press harder than expected — but keep the pressure on! When you hear a "click" and both side ejector clips snap up around the module, you know it is installed correctly.

Tip: Try to avoid touching the gold pins at the bottom of your module. You probably won't harm them if you do touch them, but it's better to be safe than sorry
