为什么计算机速度变慢
如果您的计算机拥有一段时间，那么有许多问题可能会导致它变慢。其中许多是您无法控制的，但有些不是。
这些问题包括：
- 已安装软件的内存泄漏
- 电涌和正常使用会降低系统组件
- 由于老化和使用导致硬盘驱动器扇区损坏或内存芯片损坏(bad memory chips)
- 没有安装足够的内存
- 启动时启动过多的软件
- (Malware)消耗系统资源的恶意软件和病毒
即使您无法控制正常老化的影响，但您可以做很多事情来加速您的计算机(speed up your computer)。其中包括对硬盘进行碎片整理(defragmenting your hard drive)、执行病毒扫描和禁用用户帐户控制 (UAC)。
但是，您可以对系统性能产生的最显着影响是确保您的内存使用得到充分优化。
1. RAM Hogs：低垂的果实
清理正在使用的内存的最快和最简单的方法是确保没有系统进程消耗所有系统资源。
随着时间的推移，这是一个容易出现的问题，特别是如果您有安装大量软件的习惯。还有一个非常简单的解决方案。
检查任务管理器(Task Manager)中列出的系统进程并查找您不认识的消耗过多
RAM的问题应用程序。
- 右键单击Windows任务栏并选择任务管理器(Task Manager)。
- 单击“进程(Processes)”选项卡。
- 按(Sort)内存(Memory)对进程进行排序，并在列表顶部查找您不认识的程序。
如果您发现任何有问题的应用程序，请进入控制面板(Control Panel)，单击程序和功能(Programs and Features)，然后卸载那些有问题的应用程序。
2.清理启动程序
不幸的是，解决内存问题和释放
RAM通常并不容易。随着时间的推移，您安装并忘记的软件可能会嵌入到您的系统中，但可能不会
经常消耗RAM 。
在这些情况下，这些程序不会显示在任务管理器(Task Manager)列表的顶部。但是，它们是每次您的计算机启动时启动的程序列表的一部分，并有助于消耗您的可用RAM。
- 仍在任务管理器(Task Manager)中，单击启动(Startup)选项卡。
- 按启动影响(Startup impact)字段对列表进行排序。
- 识别(Identify)您不认识或不需要的应用程序。
- 右键单击(Right-click)应用程序并选择禁用(Disable)。
当这些程序中的每一个启动时，它们都会单独吞噬一些内存。它们都在后台运行并消耗您的RAM。禁止它们在启动时运行可以防止这种情况发生。
3. 关机时清除页面文件
每当您关闭计算机时，系统RAM总是会被清除。但是，存储在硬盘上的页面文件不是。
页面文件是物理硬盘驱动器的一个区域，当物理RAM已满时，操作系统将其用作额外RAM 。确保页面文件像RAM一样被清除将在您下次启动计算机时保持清洁和高效。
您可以通过将ClearPageFileAtShutdown
注册表项设置为 1 来启用此功能。默认情况下，Windows 10 将此设置为 0。启用此功能很容易。
- 单击开始菜单并键入Regedit。单击Regedit 运行命令(Regedit run command)。
- 这将打开注册表编辑器(Registry Editor)。导航(Navigate)到 HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession Manager 内存管理。
- 双击右侧的ClearPageFileAtShutdown键。(ClearPageFileAtShutdown)
- 将数值数据(Value
data)字段设置为1，然后单击确定(OK)。
下次重新启动计算机时，页面文件将清除。
4. 检查设备驱动程序问题
随着时间的推移，设备驱动程序会更新，各种Windows更新可能会导致驱动程序文件损坏或驱动程序冲突。这些问题有时会导致内存泄漏，并且您的计算机运行时间越长，可能会导致RAM消耗过多。
确保您的系统没有设备驱动程序问题很重要。您可以使用设备管理器(Device Manager)快速检查。
- 打开控制面板(Control
Panel)并双击设备管理器(Device
Manager)。
- 展开(Expand)设备管理器(Device Manager)中的每个分支并查找黄色解释标记图标。这是驱动程序问题的警报。
- 如果您看到警报，请右键单击设备并选择更新驱动程序(Update driver)。
如果可以，请尝试让系统在线查找最新的驱动程序。否则，您需要访问制造商网站并下载最新的驱动程序。
清除任何设备问题并更新所有驱动程序将确保您的系统运行顺畅，并且驱动程序不会导致内存问题。
5. 减少 Windows 视觉效果
Windows 10 为窗口、菜单、工具提示等提供了许多繁忙的视觉效果。如果你有足够的内存(RAM)，这些视觉效果就不是问题。
但是，如果您使用最少的可用RAM运行，禁用这些效果可以显着增加可用内存。
要禁用 Windows 视觉效果：
- 打开文件资源管理器，右键单击这台电脑(This PC)，然后单击属性(Properties)。
- 在此窗口的左侧，单击高级系统设置(Advanced system settings)。
- 在“性能”(Performance)
部分中，单击“设置”(Settings)按钮。
- 在性能(Performance) 选项(Options)窗口中，选择调整以获得最佳性能(Adjust for best performance)。
您会注意到此设置禁用了所有动画功能。如果需要，您可以改为选择Custom，然后启用任何您离不开的视觉效果。
6.刷新内存缓存
当您频繁打开和关闭应用程序时，有时某些程序在关闭时无法正确释放系统内存。随着时间的推移，这些孤立线程会消耗RAM并导致系统性能下降。
您可以创建一个非常简单的快捷方式，该快捷方式将刷新内存缓存并清除所有丢失内存的旧蜘蛛网。
这个快捷方式是：
%windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks
如果您不确定如何配置此快捷方式，可以阅读刷新内存缓存的指南，(guide to flushing the memory cache)该指南将引导您完成所有步骤。
7.添加更多内存
当然，释放更多内存的最简单方法之一是增加现有的RAM量。
如果您不确定您的计算机需要什么样的内存，您可以使用Crucial Advisor在您的 PC 上运行扫描并找到最适合购买的内存。
扫描快速简单，生成的网页将列出您系统可用的所有存储卡。
记忆很重要
在您可以做的所有提高旧计算机性能的事情中，没有什么比清除或提高可用RAM更有效的了。
由于物理RAM(RAM)已满，您的计算机对硬盘驱动器和页面文件的依赖越少，您的计算机运行速度就越快。
7 Ways to Clear Memory and Boost RAM on Windows
There arе fеw things quite as
annoyіng as a computer that’s starting to run slow.
As good as the Windows 10 operating
system is, Windows computers still have the problem of running much more slowly
over time.
In this article, you’ll learn seven of the most effective ways to clear out old memory and boost available RAM in a Windows machine that’s suffering from performance issues.

Why Computers Slow Down
If you’ve owned your computer for a
while, there are any number of issues that can cause it to slow down. Many of
these are out of your control, but a few aren’t.
These issues include:
- Memory leaks from software you’ve installed
- Power surges and normal usage degrading system components
- Bad hard drive sectors or bad memory chips due to age and use
- Not installing enough RAM
- Excessive software launching at startup
- Malware and viruses consuming system resources
Even though you can’t control the effects of normal aging, there’s a lot you can do to speed up your computer. These include things like defragmenting your hard drive, performing virus scans, and disabling the User Account Control (UAC).
However, the most significant
effect you can have on system performance is making sure your memory usage is
fully optimized.
1. RAM Hogs: Low Hanging Fruit
The fastest and easiest way to clear up memory that’s being
used is to make sure there are no system processes consuming all the system
resources.
This is an easy problem to develop over time, especially if
you’re in the habit of installing a lot of software. There’s also a very easy
solution.
Check the system processes listed in the Task Manager and
look for problem applications you don’t recognize that are consuming excessive
RAM.
- Right click the Windows task bar and select Task Manager.
- Click on the Processes tab.
- Sort the processes by Memory and look for
programs at the top of the list that you don’t recognize.
If you spot any problem applications, go into the Control Panel, click on Programs and Features, and uninstall
those problem applications.
2. Clean Up Startup Programs
Unfortunately, resolving memory issues and freeing up your
RAM is not usually that easy. Over time, software you’ve installed and
forgotten about can get embedded into your system but may not consume RAM
constantly.
In these cases, these programs won’t show up at the top of
the list in the Task Manager. However, they are part of the list of programs
that launch every time your computer starts and contribute to chewing away at
your available RAM.
- Still in the Task Manager, click on the Startup tab.
- Sort the list by the Startup impact field.
- Identify applications you don’t recognize or
don’t need.
- Right-click on the application and select Disable.
When each of these programs launch, they devour a bit of
memory individually. They all run in the background and consume your RAM.
Disabling them from running at startup prevents this from happening.
3. Clear Page File at Shutdown
Whenever you shut down your computer, the system RAM is
always cleared. However, the page file that’s stored on the hard drive isn’t.
The page file is an area of the physical hard drive that the
operating system uses as extra RAM when the physical RAM is full. Ensuring that
the page file is cleared just like RAM is will keep things clean and efficient
the next time you start your computer.
You can enable this by setting the ClearPageFileAtShutdown
registry key to 1. Windows 10 has this set to 0 by default. Enabling this is
easy.
- Click the start menu and type Regedit. Click on the Regedit run command.
- This will open the Registry Editor. Navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management.
- Double-click on the ClearPageFileAtShutdown key on the right.
- Set the Value
data field to 1 and click OK.
The next time you restart your computer, the page file will clear.
4. Check for Device Driver Issues
Over time, device drivers become updated, and various Windows updates could lead to corrupt driver files or driver conflicts. These issues can sometimes lead to memory leaks and the longer your computer is running, could lead to excessive RAM consumption.
It’s important to make sure your system is clear of device
driver issues. You can check this quickly by using the Device Manager.
- Open the Control
Panel and double click Device
Manager.
- Expand each branch inside the Device Manager and
look for a yellow explanation mark icon. This is an alert for a driver issue.
- If you see an alert, right click on the device
and select Update driver.
Try to let the system look for latest drivers online if you
can. Otherwise you’ll need to visit the manufacturer website and download the
latest driver.
Keeping any device issues clear and all your drivers updated
will ensure your system is running smoothly and drivers aren’t causing memory
issues.
5. Reduce Windows Visual Effects
Windows 10 comes with a lot of busy visual effects for
windows, menus, tooltips and more. If you have plenty of RAM, these visual
effects aren’t an issue.
But if you’re running with a bare minimum of available RAM,
disabling these effects can significantly increase available memory.
To disable Windows visual effects:
- Open File Explorer, right-click on This PC, and click on Properties.
- On the left side of this window, click on Advanced system settings.
- In the Performance
section, click the Settings button.
- In the Performance Options window, select Adjust for best performance.
You’ll notice that all the animated features are disabled
with this setting. If you want, you can instead select Custom, and then enable any of the visual effects that you can’t
live without.
6. Flush Memory Cache
When you open and close applications frequently, sometimes
certain programs don’t properly release system memory when closing. Over time,
these orphan threads consume RAM and lead to slow system performance.
There is a very simple shortcut you can create that’ll flush
the memory cache and clean out all those old cobwebs of lost memory.
This shortcut is:
%windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks
If you’re not sure how to configure this shortcut, you can read a guide to flushing the memory cache that’ll walk you through all of the steps.
7. Add More RAM
Of course, one of the easiest ways to free up more memory is
to boost the existing amount of RAM you have.
If you’re not sure what kind of memory your computer takes,
you can use the Crucial Advisor to run a scan on your PC and find the best
memory to buy.
Scans are fast and easy, and the resulting web page will
list all memory cards that are available for your system.
Memory Is Important
Of all the things you can do to boost your old computer’s
performance, there is nothing as effective as clearing out or boosting your
available RAM.
The less your computer needs to rely on your hard drive and
the page file because the physical RAM is full, the faster your computer will
behave.
