Slow PC? - Now Make Your Computer Faster
When you use a new Windows system, no matter it's Vista, XP or even older systems, it will run slower and slower over time. Because there are tons of problems accumulating when you implement a process or task, and you just don't notice it.
Many things can cause Personal Computer runs slow. Junk files, unnecessary startup programs and corrupted or missing registry keys have great impact on computer performance. Many people underestimate the effect of those factors to the Personal Computer performance.
When your hard disks are stuffed with too many junk files, the data access speed could be very slow. That is the reason why it takes you a long time to open a Word document file, audio or video. You should clean up some unnecessary files from hard disk and save limited space. This could improve the data access speed to some extent.
Too many start up programs can also slow down the Windows boot. The more start up programs you enable, the slower Personal Computer boot up. It takes time for Windows to access the data and registry key value of the program. To speed up the Windows startup, you should disable some unnecessary programs.
One of the most important parts in Windows XP and Vista is the registry. Registry stores the data which is vital to Windows and all programs. when you install a program, the data must be stored into registry before you can run it. If one registry key of the program is corrupted and missing, you probably cannot run it.
If one registry key of Windows system is removed or changed by some accidental or illegal processes, it will lead to the computer running slow, Svchost.exe error, ActiveX error, DLL error, blue screen or even crash. It is vital to regularly clean up invalid keys and repair the corrupted keys.

What is SATA Hard drive?
Every computer stores the information saved in its memory on its hard drive. A hard drive is a set of disks held up on a central spindle, and each disk is made up of many tiny magnetic bits. An antenna, called a read-write head, encodes information onto these disks by using an electromagnetic flux to change the magnetic polarity of the bits that make up the disk. The more disks a hard drive has, and the more bits on each disk, the more memory space is available in the hdd. Different computers are specialized for different uses, so there are also different kinds of hard drives that are compatible with different kinds of computers. The three types of hard drives that you are most likely to encounter are SATA hard drives, PATA hard drives, and SCSI hard drives.
SATA hard drives, otherwise known as Serial ATA drives, are the cheapest variety of hard drive on the market. They are the newer variety of Parallel ATA hard drives, or PATA drives, which used to be the most common type of hard drive. Within the past two years, the SATA drive has almost completely taken the PATA drive's place as the most common hdd. The SATA hdd was designed for high bandwidth applications, such as multiplayer video games and video editing, so it is much faster and performs more efficiently than the traditional PATA drive. Also, SATA hard drives are easier and less costly to manufacture than PATA drives, so SATA hard drives are much cheaper in stores. The cable used to plug in the SATA variety of hard drive is more advanced than that of the PATA hard drive. The plug the cable uses to connect to the motherboard is smaller and cheaper, and it is easier to plug in without damaging the connector pins on the motherboard. Some of the newer models of the SATA hard drive do not work with the older cable ports on a computer's motherboard, so you may have to buy a SATA adaptor cable.
SCSI hard drives are of an even older design than the PATA hard drives, but they are still used today because they function much faster. They cannot hold as much information, and they are far more expensive than their SATA counterparts, but if you spend a lot of time on fast-paced network servers, or use other high speed, high bandwidth applications, you may want to consider using a SCSI hard drive.
The most important thing to remember when you are buying a hard drive is to get one that is designed for the motherboard your computer uses. If your motherboard and your hard drive are designed to work with each other, they will be more efficient than if you use an adaptor cable.

Computer Freezing - The Right Way to Fix It
There is almost nothing as frustrating as a computer freezing up on you. This can be especially disturbing if it happens in the middle of something important like writing an important document, doing your taxes or in the heat of a computer game. As the medicine commercial goes, you need relief and fast.
Causes of Freezing
There can be many causes of freezing up. The most common ones are:
- computer overheating
- viruses or trojans
- registry problems
- Windows corruption
- video driver problems
- a faulty program
- flaky RAM
- hard disk going bad
1. The rule in computer problems generally is that the latest change caused the problem. If you recently installed some new software or hardware, uninstall it and see if the problem goes away. If it does, then the new thing is the cause. Check on the Internet for any known problems with these things or contact the vendors for repair suggestions.
If this doesn't apply, Windows keeps track of errors in the event viewer. Click start->run, type eventvwr.msc and enter. Click on system and look for any error reports in the right column. If there is a link in the error report, click on it to get the details. The link will often provide you with a possible solution.
Do the same for application and the other choices on the left hand side until you find something that applies to your problem.
If you found the cause of your error, follow the suggested steps to correct the problem.
2. Computer overheating - Check to make sure your fan is not being blocked. It would also pay to open your case and clean out any accumulated dust or junk.
If you open it, make sure to unplug it first. Additionally, you should touch the case to release any static electricity before touching anything inside the computer.
3. Viruses or Trojans - Make sure that you have quality Internet security software such as Norton 360. Download and run Malwarebytes to get rid of any malware that you might have.
4. Registry Problems - Use a high quality registry cleaner to correct these problems. I have found JV 16 utilities to have one of the best and safest registry repair utilities.
5. Video driver problems - update your driver to the latest version going to the device manager and getting the latest version.
6. Windows corruption - If your Windows operating system has gone bad, you need to repair it. The type of repair that you can do depends on your operating system version Windows 2000, XP or Vista.
7. Other causes - The causes above are the most common ones.
If you always have the problem with a particular program, contact the vendor. You can easily find their support by Googlingsupport contact.
RAM problems can be checked out by using free memory diagnostic programs.
If you suspect that your hard disk is going bad, do the following Click Start --> My Computer. Right click on the disk you want to check (usually C: ). Select Properties. Click on the Tools tab. Under Error Checking, click Check Now. Select the Automatically Fix File System Errors option, and the Scan For and Attempt Recovery of Bad Sectors option. Click on Start.
