Diagnosing Computer Hardware Faults

When your PC goes wrong and you have lost all hope the normal final sTAGe is to reformat your Computer and start versions of fresh. This will most likely resolve any software issues, remove viruses or any other nasties and give you a clean start. But what happens if you have already reformatted and the problem still exists?

Diagnosing Computer Hardware Faults

This means, most likely, you have a hardware fault. This is where problems can start.

Diagnosing a Computer hardware fault can be a right pain as any of the computers components could the causes. Unless you are intending to replace the enTire machine you need to carefully diagnose with what components the fault lies with.

I would advise you look at the computer into these main areas to analyse.

Memory /RAM

Power Supply

Hard Disk

Motherboard

This isn't a definitive list, obviously depending on your issue ie if your issue is that you don't get sound then it could be a sound card issue, similarly if you don't get a display then graPh Meter and check the volTAGe and current coming out.

Hard Disk-this can be one of the worst problems to have as if your hard drive does fail, unless you have been responsive and done regular backups of your most valuable data, you standto lose it all. Hard disks can go at any time and usually you will hear a harsh sounding clicking noise that is coming from your computer. If this is the case you need to probably replace the hard disk. Get someone who then knows what they are doing here to try and recover your old data for you.

If none of the above solves your problem then you could possibly be looking at the fault being with the motherboard or any other Plug in cards or devices you have. Remove everything to leave only the very basics. Take out all sound cards etc and any other PCI devices that are not essential. If you have more than one stick of ram then leave in only one and see if the problem resolves.

Windows was designed to perform a "Physical Memory Dump" when your Computer hits an error or problem. This basically means that whenever Windows hits a problem that's too big to overcome, it simply hits the "panic" button and restarts. But instead of restarting immediately and risk corrupting all your settings and files, your Computer attempts to maintain the integrity of your system by "dumping" your currentsetup to your hard drive. This error is characterized by a blue screen and restart from Windows. It's caused by two very common problems.

The first cause of the Physical Memory Dump error is actually the hardware of your PC. This error is initially caused by the incompatibility of certain pieces of hardware on your system. If you have just upgraded any hardware or have installed some new hardware, then you should remove it and revert back to your old setup immediately. Computer equipMent is extremely complicated and it should come as no surprise that various components from different manufacturers don't work with each other. You should find replaceMent upgraded hardware if you're getting the physical memory dump all the time.

Different Types of Human Memory

The process whereby memories are forged into the Mental system is a remarkable one that is often misunderstood. But by studying the nature of memory, we gain a higher insight in to the intricate workings of this most vital aspect of the human brain. Some compare the human memory to a tape recorder-yet it is not so simple. While memory can serve as a retainer for key data that we want to "re-play" over and over again, it is a more dynamic and complex mechanism. In addition to storing information, it also allows us to recall feelings, sensations, images, as well as carry out basic functions such as talking.

Different Types of Human Memory

Since human memory is such a complex system, it cannot be nailed down to an exact science. In fact, cognitive psychologists working in thefield of memory often have disagreeMents. What has been established is that there are three main types of human memory -sensory, short term and long term-plus a fourth related faculty called the working memory.

When we speak of "sensory memory," we are referring to the few split seconds that follows the initial perception of an object. If you are able to briefly look at something and immediately memorize its details, then that is an instance of sensory memory. Usually, in these cases, when you are only able to see something for a few split seconds, you might feel like you saw a lot more than you are able to describe.

Some of the data that is perceived in a sensory memory will subsequently be transferred to a short term> memory. We call short term memory the ability to recall something from several seconds to a minute ago.

There is also a type of memory that is referred to as working memory. It can be viewed as a form of short term memory, in that it refers to the limited store that is needed in order for certain Mental tasks to be performed. Whereas short term memory is rooted in duration, working memory is defined by purpose. Baddeley's Model of Working Memory defines three components to this type of memory -the verbal store, the visuo-spatial sketchpad, and the central executive, which determines control and rehearsal.

Finally, there is long term memory. Unlike short term and sensory memories, which disappear in abrief amount of time, long term refers to memories that can be stored for a period of up to several years. Psychologists disagree on how long term memory works. Some argue that a long term memory remains in the brain forever, but this is impossible to prove, as there has never been a human being who has lived forever!

While it was once thought that there was no real determining factor between what made in short term memory and long term one, research has since established that the brain contains numerous systems of memory and that information is constantly being transferred among these various systems. Hence, the ongoing research in to the mysterious nature of how memory works.
