[COLOR][SIZE]Slow or Freezing Windows 7[/COLOR][/SIZE]
System Start-up packed with too many applications (Start-up overload)
As you continue to add applications to your computer, many of these applications are setup to automatically load when Windows boots up. Additionally, these applications can add themselves to a hidden area of your Windows Operating system; the registry. In extreme cases, this can cause your computer to practically freeze.
Limiting the number of applications loading themselves at start-up frees up memory, which can speed up your computer considerably and increase overall system performance.
Spyware
Malicious applications that bury themselves into your Windows registry and core file system can cause a lot of computer issues, especially a slow computer.
These programs are usually installed unintentionally and without permission of the user. Spyware can cause a variety of issues such as security breaches, but are most notably known for the ability to slowdown your computer when surfing the web. e spyware programs must be removed as soon as possible to return your PC to top running speed, and before they damage your file system.
Bloated and Corrupted Windows Registry
The Windows registry is like the gatekeeper of your operating system. Corruption or a registry overload can result in a variety of pc performance problems, including poor application startup times, slow Windows start and shut down, and inability to resume from computer hibernation/sleep mode.
Cleansing, optimizing, and compacting your Windows registry can drastically improve your computer’s performance by fixing a variety of issues.
Hard Drive Fragmentation
The fourth most common reason for a slow PC is a fragmented hard drive and file system. Over time, as you install, delete, and move files around your hard drive, you computer’s hard drive slowly degrades and becomes fragmented. This causes files to become scattered into bits and pieces all over your computer’s hard drive. Windows has a built in tool to help you with hard drive defragmentation.
Remnants of uninstalled programs
Even if you uninstall applications properly, sometimes remnants of the uninstalled program are left behind. These remnants occasionally can affect the speed of your computer. Not surprisingly, these remnants are left to disrupt and waste space inside your Windows registry. This residue of old program registry entries sit their clogging up your PC’s core.
Insufficient RAM
It’s very typical for your computer to not have enough short term memory (known as RAM) to process all of the applications you’d like to run simultaneously on your computer. The only way to increase your RAM is to buy more of it since it is hardware.
Hard Drive full with windows and internet temp files
If your hard drive has less than 5% of free space, there’s a strong chance your computer will perform at a dramatically slower speed. To fix this, free up some space by removing old documents you no longer use or programs that are no longer needed.
