I’ll be adding new articles all the time. If you have any ideas for new guides – let me know (I’ll make them for you).

Ad 1.Bsods , Computer Problems - Reference Book


During the critic error of Windows OS our computer restarts by itself or displays BSOD
( blue screen of death). This message contains line of numbers which can help with realizing what is wrong in our PC:

0A – operating memory modulus error – Try to check your memory cards with program named MEMTEST. Probably your RAM dice is broken. If you have more than one dice you should check each one of them. This is the way to eliminate working RAMs and find that broken one.

Did you add RAM to your PC ? That might be a problem. Dice may not be compatible with each other so try to remove one of them.

0D – CPU error – Such an error might be caused by CPU’s overheating or its damage.
Check out quality of CPU’s cooling system, try removing dust from ventilator and radiator.

0E – errors related neither to CPU nor to RAM – Check informations above.

When we know entrire line of error’s numbers we can look for it here :
http:// search.microsoft.com/ or www.google.com.

Microsoft’s forums and google are full of information about such stuff.
A lot of users had same problems and got them solved!


http://www.dashboardwidgets.com/showcase/data/57/BSOD-0p6b.png


1. Hardware overclocking reasons :

a ) Overclocked CPU – unskilfully overclocked CPU causes our that PC is unstable, restarts by itself, displays BSODs.
b ) Overclocked graphic card – unskilful GFX Card overclocking may result in deformed display on our monitor, can also cause restars of our PC.
c ) Overclocked RAM – this may cause CRC problems, errors during copying on HDD, PC may also restars by itself.


2. Non-overclocked hardware reasons :
a) PSU – power supply unit – A lot of people, while buying a PC, think about good CPU, GFX card, RAM but they forget about good PSU that can support such a machine.
Low PSU may not cope that PC and it will get ‘stoned’ or reset while working. It’s really important to buy only brand name PSUs because they will assure proper working of our PC.
List of lower PSUs :
Bestec, Codegen, Colorsit, Feel, Procomp, Ropla, TakeMe, Tracer, Tronje, Q-Tec, Impet, Linkworld, Logic , Medion, Megabajt , Mercury, Modecom FEEL, Mustang.
Those PSU will support only slower PCs like those used in offices which don’t require such an amount of power.
PSUs listed below will support stronger PCs used to play games and GFX works :
Aerocool, Akasa, Amacrox, Antec, BeQuiet, Chieftec, CoolerMaster, Corsair, Silver Power, SilverStone, Tacens, Tagan, ThermalTake, Topower, Yesico, Zalman, Enermax, Etasis, Gigabyte, Hiper, HuntKey, Modecom MC, Mushkin, NeoTEC, OCZ, Pentagram, Seasonic

b ) Memory – like above, test it with MEMTEST program.

c ) CPU – probably it’s overheating – check the cooling system

d ) HDD – probably contains bad sectors – check disk with HD Tune

e) Wires and tapes – very often they are getting used by removing/ plugging in something into our PC. They can be simply replaced by new ones.


3. Viruses, spyware etc.
They can also cause a lot of problems on your Pc. Remember to always have an updated database of your antivirus program. You should use antispyware programs as well.
I recommend those : SpyBot Search and Destroy or Ad-Aware.


4. Drivers.
Remember to always download drivers from producers official download site.
Try to keep them updated, but sometimes, when you have problems with the newest version it’s highly recommended to use the older version which works fine with your hardware.

When you are changing drivers you should use Driver Cleaner which will erase trash left by previous driver on your PC.

5. Registry
It happens very often that something is missing in our registry or few entries are broken. I recommend you to use program Ccleaner which contains registry fixer.



Most important advice as for conslusion :
If you havent found help in my guide try to search for it in www.google.com.
It doesnt bite and helps a lot!

Ad 2.Deleted Files , Lost Partition - Reference Book



Even though you deleted important file from your trash bin that doesn't mean it's gone forever!
It is just invisible for you, it can be overwritten later what makes recovering much harder.


1. How to recover lost files ?


I recommend you a program named FreeUndelete.
Run the program > choose a disk you want to look for deleted files on > click Scan.
The program will automatically look for those files which are able to be recovered.
Such a files will be marked as GOOD. Overwritten files will be marked as POOR.
Afterwards you have to choose a folder that you want recovered files to appear in.

Another program you can use to recover files is R-Studio but it's not free but more advanced and in my opinion efficient.

2. How to recover lost photographies ?

You can do it by the same way as described in 1. but you can use other program designed for photos recovering.
PhotoRec is a program which is being ran under DOS. After opening it all disks will appear ( including memory cards).
You have to choose type of the partition :
- if the card was formatted under windows - Intel type
- if the card was formatted under apple - Mac type
You have to choose the device you want to be scanned and format of the files you want to be recovered.

3. How to recover lost partition ?

When your partition has been erased and nobody knows why Partition Manager 8 will help you!
After opening the program click Undelete Partition -> choose the disk and click Next.
After scanning partitions will appear. Mark this one you want to recover then click Next > Finish > Apply.
Partition will be recovered.

Ad 6.Linux – adequate rival for Windows



Linux – from the beginning Linux was controversial for Windows users. Now it’s known around the world and gains new fans every day. I’ll try to present it to you.

Linux’s advantages:

* Stable
* Safe – even without antivirus software
* Free (you have to pay only for some versions)
* Public source code – no secrets about it
* Can be adapted to individual needs
* Made by profesionals collaborating with a world-wide society
* In distribution form contains a lot of useful software from all categories
* Possesses more functions without extra software
* All errors can be analized and fixed by the user or reported to the producer

Now, I’ll describe some of Linux products. I hope that it will be helpful to you. If you are more interested, I encourage you too look for informations in the Internet, because it would take forever to describe them all.

Some of Linux products:

Ubuntu: free product of GNU/Linux made by Mark Shuttleworth with Canonical company. Designers of Ubuntu wanted to make a product simple in usage, functional and with easy software instaling and using proces. Now it’s one of the most popular products all over the world .

Mandriva: one of the leading products for general use. It’s good for beginners and pro users – more popular among beginners and home users looking for a alternative operating system.

openSUSE:
GNU/Linux product sponsored by Novell company mainly used in desktops. It’s a good alternative for Windows XP for a average user. Contains well done grafic configuration tools: YaST and SaX2. openSuse is simple in instalation an usage.

Debian:
uniwersal and stable GNU/Linux product. It has a big mount od packs and a perfect tool for instaling them (APT). Debian is a good choice for a server and a desktop.

Fedora: product for universal usage. It’s also good for a specjal server and a desktop (home or work use). In all those possibilities it will need some changes in default settings – to our personal preferences and needs.

Slackware:
oldest for all working Linux products (first version is from 13 July 1993). Motto of this product “because it works” is a result from a KISS rule (keep it simple stupid). It’s a Debian for pro user, who are not afraid of the console.

MEPIS: another interestign and popular product based on Debian – for rookies. Made in year 2002 by Warren Woodford – MEPIS surprised many users with its functionality and easy usage.

PLD: system for servers and desktops. Popular product among pro user. PLD stands out from other products, because of: poldek, great pack manager, very well writen rc-scripts and default settings.
