In desktop computer have several hardware we can upgrade. But before that, you need to know how to upgrade. Read this guide before you do so.

A ) Upgrade CD-ROM Drive
- In desktop normally casing have 4 tray for cd-rom drive. If your HDD using SATA, You have no problem to use 4 CD-ROM drive. Just set which one CD-ROM number 1, 2, 3 & 4. CD-ROM number 1 & 3 set the jumper as master and CD-ROM drive number 2 & 4 set the jumper as slave.

IDE cable

B ) Upgrade HDD
- We will upgrade HDD if your capacity is not enough. However the old HDD still can use. You need to know what type and RPM speed your old HDD. Example, your old HDD IDE type and 7200 RPM. Please buy the new one with same type & RPM speed. Now days many HDD have 7200RPM and using SATA type. If your old HDD 5400RPM and you buy new HDD 7200 RPM, your computer will follow the lowest speed. One more thing, if you plan connect your new hdd with the same IDE cable with old HDD, you need set jumper. Old HDD (operating system inside) as a master & new HDD as a slave. It will different way to set jumper depend on how you want connect your HDD (related link). To set jumper, please refer top op hdd diagram.

C ) Upgrade RAM
- Before upgrade, there have several things you need to know. First, what type & frequency of memory you used now. Second, how many RAM slot you have & lastly how many megabyte max you can put. For example, now you using 1gb DDR2 PC5300 RAM. So buy same exactly the old one. Some of motherboard support more than 1 frequency example PC5300 & PC6400. Yes you can buy PC6400 too but your computer will follow the lowest RAM. Your lowest RAM is PC5300.

DirectX 10 for Windows XP

Since Vista launched, all computer user's excited with DirectX 10, especially computer gamers. But DirectX 10 only for vista. As Microsoft has announced that the DirectX 10 currently support to Windows Vista only. Now days DirectX 10 can used by winxp user too. How ever it's still in development process. But Alpha version has released and it's not the original of DirectX 10 from Microsoft.

However, Cody Brocious the Alky Project leader has released a full preview of DirectX 10 Alky preview compatibility libraries for Microsoft DirectX 10 enabled games. These compatibility libraries allow the use of DirectX 10 games on platforms other than Windows Vista , and increase hardware compatibility even on Vista, by compiling Geometry Shaders down to native machine code for execution where hardware isn’t capable of running it. No reason for gamer to change or upgrade the OS and video card(s) to play the latest games.

Here are some pictures sample to difference’s from DirectX 9 and DirectX 10 on images quality.

DX 9 scenery from Flight Simulator X

And a rendering of the same scenery with DirectX 10

If you’re serious computer gamer, i highly recommended you give a try download on Direct10X for windows XP and install it. Then you feel the differences especially on the images rendering and images processing. However, Do it carefully !!!!

Download Speed

Some of us having problem with download speed and not sure what happen. There have several reasons why speed connection very slow or lagging. But you need to know why this happen. As we know many country using copper wire as a material but some others country using fiber optical which less resistant and internet connection very fast.

Speed connection depends on many factors such as:

1. Platform
- Different speed of download using torrent in platform windows and platform linux is very big. I got this information from my best friends and he had try using two different type of operating system. The result is:

Windows platform: download speed not very good
Linux platform: download speed better than windows

But I'm not sure how big the different is but I will check with him later.

UPDATE: according to my friends, if using torrent & using windows platform average speed around 5kbps to 10kbps but if using linux platform average speed around 100kbps to 150kbps. It's look likes almost 100% more fasters speed download if using linux platform

2. Application
- So many downloader applications nowdays but I prefer using IDM. I tried it by myself and
IDM claim that IDM application 5X more faster with any applications. Yeah thats true.....

3. Package
- Need more speed? Don't use below than 1mb speed. If you using 512kb, so you know why your internet line slow and you know your mistake.

4. ISP
- Some of Internet Service Provider is very slow even you used 1mb or 2mb internet connection. So please survey before you subscribe with any ISP's.

5. Server source
- Some server source set a limited speed to a free user and more faster to paid user. So if you want faster than before, pay the price and enjoy with the speed. But depend on server, some server very high speed download for free user. So don't asume all servers are same spec and same setting.

6. Download time
- You need more speed download connection? Download anythings you want at night till morning. Internet traffic is really good that time. You need to know what peak time of internet connection. Normally start from 8AM until 6PM internet traffic very poor. So don't download that time.

Open Office / Ms-Office

Now days, many peoples using openoffice because it alternative application from ms-office. Why? you need spend a lot of money if you want to buy ms-office but different situation with openoffice, it's free. Many advantage if you used openoffice example:

  • it's free
  • compatible with almost all systems platform
  • can create pdf file using writer (knows as word in ms-office)
  • can open word, excel & power point file
  • can install in any languages even in malay

But problem start from ms-office launched new application MS-OFFICE 2007. This problem just because of file type. In ms-office 2003, file word using *.doc extention but in ms-office 2007 word using *.docx

So the problem is, openoffice can't open the *.docx file, even excel & power point file (ms-office 2007) . In ms-office 2003, the problem is openoffice can open any files but sometimes all setting is mess up.

So how to solve this 2 problems? It's simple, download and install word viewer, excel viewer & power point viewer on your computer. This application can view those file but can't edit or add anythings. Most important is, you can still view the files and can printout.

The second problem is, we can't view the ms-office 2007 files. It's simple, just install "file format converter" and after that you can view all ms-office files. Still same, can't edit or add but can still view & printout.

DIY: Network Cable - RJ45

Before we start, several tools must have near you.

1. Cable network
2. Crimping tool
3. Cutter
4. Network tester
5. RJ45

Make sure how long you need for the cable. Example if the distance is 10 meters, cut the network cable to 11 meters. We need more because if you make mistake we can do it again with same cable.

Cut & remove cover of network cable. Remove it around 2cm

As you can see, my crimping tool have cutter on it. Cut it off

After remove, it's will look like this


Make cable look like this (see the picture)

As picture show, some is short and some is not

Cut the edge of cable and make it same.

This is the result

Manage the all color cable same as note above. Don't make mistake in this stage

Put in RJ45 soket after you make sure it's manage as diagram above

1 small slot for 1 small cable only, so please careful on this step

Put it into crimping tool and crimp it harder.

See picture above

After finish both side, put it in tester

The other side also put it in tester

Switch on the tester.
If the green lights on from number 1 to 7, thats mean successful.
If the lights on looping number or others number light is not come out,
thats mean you make mistake

If lights not on from 1 to 7, identify which side have problem and then cut it off
and repeat step2 until it's working properly
