Understanding LCD Display Dead Pixels

A liquid crystal display (LCD) is a thin, electronic flat panel used to display information and images. It includes monitors for computers, televisions, instrument panels, and other devices ranging from aircraft cockpit displays, to every-day consumer devices such as video players, gaming devices, clocks, watches, calculators, and telephones. LCDs are simply everywhere now.

Its major features and benefits are: lightweight construction (compared to Plasma displays); portability (in the case of smaller displays); the ability to be produced in much larger screen sizes than were practical for older Tube (CRT) displays; and perhaps most important, its much lower power consumption.

The problem that Windows 7 has is nothing new. In fact, a slow computer is something that has been plaguing Windows systems since the invention of PC’s… but there’s a specific problem inside Windows 7 that is the main cause of its slow speed. This issue is so common that it’s estimated that 95% of computers are slowed down by it… and it’s most likely to be the cause of your slow PC today. And fortunately, you can fix this problem with a simple method.

The reason why most computers run slow is all to do with a part of your computer called the ‘registry’. This is a database which lies at the heart of Windows and stores all the settings and personalization options for your PC. It’s a central storage facility for Windows, which gives your system the ability to ‘remember’ various different settings that you might have on your system, such as which email addresses you use and even what color theme you have. It’s a very important part of your computer, but the registry is also one of the main reasons why your PC tends to run slow.

Ever since Windows ‘98, when the registry was first introduced into Windows, it’s been causing computer to run slow. And it’s all because of how important it is. The registry is so important that Windows *needs* to use 100’s of files from it constantly. This is okay, but it makes your computer confused and makes it save many of these important files in the wrong way; causing them to become corrupted and extremely hard to read.

This corruption of the registry files is one of the biggest causes of slow systems – because these files become so difficult to read. Your computer needs to read the files from the registry to make it work, but if they are unreadable, then your system cannot do that in a timely manor, making it run slower. This is still a problem for Windows 7 and the bad news is that since the more registry files that become corrupt, the slower your PC runs.

The most likely reason why your computer is running slow is because of these corrupted registry files – they prevent Windows from being able to process the files it needs, resulting in it becoming slow and unreliable. The trick to fixing this problem is to use a registry repair tool, which is a scanning utility that looks through all the registry files and then fixes any of the damaged ones that are in there. Getting these tools to speed up your PC is quite easy – you just need to install one and it will show you what to do. And if you can get a cleaner which is able to fix the most registry errors, you’ll be able to get your computer to run like new again.

If you want to Speed Up Windows 7, then one of the best ways to do it is to use a registry tool. This will scan through the registry database and fix any of the damaged or corrupt files that are slowing it down. You can Click Here to speed up Windows 7.

For years now I have been using AVG as my antivirus program and occasionally (always on others machines) I will use a couple of different antispyware programs to clean up a computer.

At work we use McAfee, which is a bit of a resource hog although it seems to be easy enough to deploy and update so in the enterprise it is incredibly popular.

Lately I have seen that Microsoft Security Essentials is all the rage. Some of the guys at work are installing it, using it, and raving about it. so when my brother in law got a new laptop that was preloaded with a trial of Norton Internet Security I told him to try the free Microsoft Security Essentials. Seemed like a good plan and I had a guinea pig as a tester.

Well things seem to have worked out. My brother in law did the Norton uninstall and the Microsoft Security Essentials install was just two clicks from the home page at Microsoft and after the update everything was done in about 10 minutes. Read the rest of this entry »
