Physical Damages of Hard disk

When clicking sound starts coming from hard disk drive, this indicates that hard drive is facing some problem. This only happens when power fluctuate while you are working on the computer. This shows that your hard disk is physically damaged.


Some of the hard disks give message when such sounds start coming that some error has reached. Such kinds of troubles are faced by many factors but most common which becomes the primary cause for its failures are given below.

Hard disk head smashed:
Hard disk magnetic plates are used to store the data on the disk and head on the hard disk supports in reading and writing of the data. When head finds any scratches on the magnetic plates; sound is produced when head revolves on the plate to that specific sector for reading or writing data. This needs to be taken care of immediately because if you start fixing the damage then it may result in further disk damage. Immediately shutdown your system and call any recovery experts for consultation. Data stored in hard disk is very sensitive it should be examined and recover in clean room labs.

Bad sectors of the Hard disk:
Bad sectors of the hard disk are areas on the tracks of magnetic plates which get corrupted due to any reason. When head try to read data from these sectors, its all attempts go in vain. Sound heard during the reading of that corrupted sectors which indicates that some of the sectors are failed and damaged.
If hard disk is very old and its condition seems to be very bad; best tip to stream line it again is to scan the whole disk for bad sectors. Scanning process will help in identification of all the damaged or corrupted areas and it will not let hard disk to write any thing on those sectors again.

Damaged Circuitry of Hard disk:
Other than the above two major reasons, additional grounds can be cause of failure of some internal components of the hard disk. It can be out of order spindle; loose head of hard disk, wrong placement of head and any disconnected connection of internal circuitry.
This is always seen that after clicking sound of your hard disk it freezes or stop working any more. Best solution to fix the damage is to take your hard disk to any famous hard disk data recovery company.

Lesser space of storage:
If stored data on hard disk cross the storage limit of hard disk then hard disk uses the technique of virtual memory paging to do the task which are left to process. Such kind of tasks increases the processing of the hard disk and raises it to exhausted state.
In order to overcome over this problem some extra space should be added, for this purpose RAM and extra hard disk is the best solution.

Top 5 Reasons Why
A Monitor Goes Blank

1. Introduction

Computer monitor problems can be very hard to troubleshoot - I mean, if your monitor goes blank, how do you check anything on your screen. So that's why it's important to have 2 monitors in the house. Usually, if I have my desktop PC's monitor going blank, I'll immediately hook up the video card to another monitor. If the screen remains blank, then it could point to a video card problem. If the new monitor displays an image, then it's probably the first monitor that has run into problems.

A typical computer monitor - don't panic if it goes blank!

Reason 1: Wetness

The number one reason why computer monitors go blank is - wetness. Believe it or not, when your computer monitor is exposed to humid air, sometimes water can condense and accumulate in the monitor. This causes the monitor to malfunction and go blank. I've had this happen to my desktop PC at least three times before. What you need to do is to leave the monitor alone for some time and allow the water to evaporate. That usually solves the problem.

Reason 2: Faulty Graphics Card

The next reason why your computer monitor goes black is due to a faulty graphics card. The best way to detect this kind of problem is to connect up a new monitor to your PC, then check if you have a blank screen. If you continue to have a blank screen, then it's likely your video card is faulty.

Reason 3: Faulty RAM

This one is less obvious and less common, but it can happen. You might sometimes get bad RAM modules which prevent your PC from booting up even to the basic BIOS startup screen. To detect this kind of problem is more troublesome, you might need to remove those RAM modules and insert them into another computer.

Reason 4: Loose Connections

Another reason why your monitor goes blank is due to loose connections. The connection from the monitor to the mains is usually a culprit, as is the connection between the monitor and the video card. Check those connections before you declare your computer monitor as faulty.

Reason 5: A Short Circuit In The Motherboard

And the final reason why your computer monitor goes blank? It's possibly because of a short circuit in the motherboard. This is the most undesirable outcome of course, as you might have to replace your entire motherboard. However, it's possible that this can happen - so keep your fingers crossed and hope it doesn't happen to you.

Conclusion

And there you have it, the top 5 reasons why your computer monitor goes blank. Make sure you do a mental check of the above points the next time your monitor goes blank - don't be too quick to declare your monitor as faulty. Until next time, happy computer building!
