Computer diagnostics in IT world covers almost any troublesome topic about computer hardware or software issues. Whether your computer is running smoothly or you are already experiencing some slow down - either way the sooner you do the necessary computer maintenance the better. It's the same with cars - the technical failure diagnosed in the early stage can be fixed and removed without much trouble, while leaving it as it is might lead to your auto breakdown. How to make simple computer diagnostics?
Well, you don't necessarily need to go to the local computer repair shop - you can do it yourself.

Things You Will Need

First you have to find any faulty hardware issues be it your video card, USB slots, or memory crashes.

1. This method is quite simple and facile:
Go to your desktop and right click on "my computer" icon.
Select "Properties" and go to "Hardware".
Select "Device manager".
In the newly opened window you have to see all your hardware parts and all of them must be without any exclamation or question marks. If there are any - it means there are some problems with this hardware part. Drivers could be missing; just check if everything is OK.

2. Hirens Boot CD is a powerful tool to diagnose any hard drive, RAM, Processor or whatever problem you might be experiencing.
It is best to use it as a bootable CD and run all the diagnostic tests. It covers wide range of hardware and software problems, even some powerful antivirus tools are included.

Concerning the software issues there are usually malfunctioning programs, old files, registry cleaners and computer viruses.
1. For the first three I would recommend using Tune up Utilities. The program is not a freeware, but you could use it for a trial period and it does not cost a fortune. I would definitely recommend it to anyone wishing to maximize the performance of a PC.

2. Referring to viruses it's a bit easier to find some free antivirus tools and utilities. The most popular and working is AVG antivirus software. The AVG process does not load too heavily on a computer memory while it is working in a real time protection mode.

However, it is not that good and does not find or fix all the viruses in your computer. Therefore, you still have to use some additional software.

3. My advice is to try Super antispyware tool. I have recently been attacked by a Trojan virus which could not be removed even by the AVG. Having tried almost everything, I decided to use the latter - and it worked. It is free software if you want to scan your computer manually. A small charge and upgrade is applied for additional functions - schedule and real time protection.
4. There are many online computer diagnostics tools available on the internet, just try to surf for them – you will find lots of free tools and useful info there.

To sum up – use the latest drivers for your hardware, clean up and defragment your drives once in a few months, check them for errors, update and run your antivirus and pc tune up programs and there will be no need to bring your computer to a repair shop.
