What will you do if Quick Time asks for a CD to run a normal video file ?

In some cases when you try to open a multimedia file with Quick Time player,it asks you to put a CD into the CD drive to open that file although it is on the hard disk. The quick solution to this problem is to put any CD into the CD Drive, but the real reason for this problem is that you have added a file that was on a CD or DVD  to the favorites menu and for an unknown reason ,the program must check if this file is exist on the CD before opening the file you want open at that moment. So, you should remove the file from the favorites or delete all the favorites by this method: open the folder " Documents and settings " then "All users" then open " Application data " then "Quick Time".
Search for the file " quicktimefavorites.qtr " then delete it. Restart your computer and this problem will completely disappear.

Seagate FreeAgent XTreme 1.5TB on the top of external hard disks

Seagate introduces the best external hard disk for 2008 and it's really amazing and you can called it "all in one". It has all what you need in an external hard disk ,the large capacity ,the smart appearance ,the flexibility that allows you to lay the HD on its side or stand it upright and the long warranty. You can also connect it to your computer by 3 ways ( USB 2.0 480MB/s ,Firewire 400 or eSATA 3GB/s) to maximize the speed of data transfer according to you computer. It has 32MB of cache to increase processing speed and its speed is 7200 rpm for best performance as the higher speeds always make the HD temperature high and this badly affect the lifetime of the device, so 7200rpm is the best speed now. I recommend this product to you , but note that ALL external hard drives may have problems with windows vista 64bit when connecting the device with eSATA and this hard may not work properly with eSATA on vista 64Bit and Western Digital hard drive also do so.
Ranking for this HD: 5/5

How to compress 1 GB to 10 MB

If you have big file or folder which consumes large space of you HDD and you want to upload it to any server ,you will need to use a powerful compression program to decrease its size and I found a perfect one. KGB Archiver can compress file to 15% or less of its original size. It is really wonderful but to do the best compression you should have a large RAMs ,but it can also work with many modes so as to work with little memory. You should try this program and save you disk space.

Corsair Dominator Twin3x2048 -1800C7DFIN just a normal DDR3 RAM

This is one of the first DDR3 RAMs found in markets and it is really good but won't meet your expectations if you think it will deliver incredible performance. It has the overclocking feature, but trust me, some of DDR2 RAMs can deliver a better performance. I know that its freq. is 1800Mhz but its real performance is normal and moreover its price is very high ( about 425$). It achieved 5430MB/s in memory bandwidth test in SiSoft Sandra and some DDR2 RAMs can achieve higher results. So I advice you not to buy this RAMs if you want a very powerful performance for games and other application.

It costs about 2200$ , so it is for the rich people who loves seeing the real full HD videos.

The worst graphics card I have ever seen

I used deffirent kinds of graphics cards but I found that the worst video cards are always the Intel's ones. These cards are slower than the NVIDIA and ATI cards and they cause many troubles with games and also slow your computer. I tried the AGP cards and also the PCIe cards and found that the Intel graphics cards give bad images in games and the they deliver only 60-70% of the ATI graphics cards performance. Intel used to put its graphics cards on its chipset to force the user to use them but now Intel introduced new chipsets without its graphics cards but at high cost. I advise you NOT to use the Intel's graphics cards as they cause high temperature inside your PC and you will find that the motherboard temperature will reach over 45'C while playing games and you will notice that games run slower  than they should. So, the best solution is to use the ATI or NVIDIA graphics cards and disable the Intel one in your PC if it is on your motherboard.

Google Chrome : High speed with big trick!

Everyone now must have heard about the powers of the new Google's browser "Chrome" and its high speed in browsing the web specially the feature of multitabbing. All that are really very good and indeed it is better than Microsoft internet explorer and also faster than Firefox ,but it has a big problem. This problem isn't inside the program itself ,but it is in what google do with its browser.The Federal Office for Information Security in Germany has warned  German people from using Google Chrome as it allows Google to reach to the personal informatoin of its users and that is what Google said in the item No.1 of Google Chrome privacy policy which give Google all rights to get to your content and publishing it. So, I advise you not to use this browser and Firefox will give you what you want: the speed and the security.

UHARC v3.06 a very powerful compression program

I tried many programs to see what the best compression program is ,but I found that WinRar isn't the best one. If you try UHARC ,you will find that it has the best compression ratio specially for files and huge games and  its compression of the multimedia files is better than any other program but not very good like other types of files. One of may friends tried to compress a 4 GB game with it and compressed it to 650MB!
You should try this program and it is also a freeware. Download it here.
