RAM可能会导致一些最令人沮丧的计算机问题。症状可能多种多样，而且有些随机：您可能会遇到系统高度不稳定、数据损坏或无法解释的行为，让您感到困惑。当您遇到此类问题时，最好在Windows计算机上测试RAM 。一种方法是使用内置的Windows 内存诊断(Windows Memory Diagnostic)应用程序。它适用于Windows 10以及旧版本。以下是如何使用它来解决内存问题并查看诊断结果：
步骤 1. 启动Windows 内存诊断(Windows Memory Diagnostic)工具
如果您想使用Windows 内存诊断(Windows Memory Diagnostic)应用程序来解决RAM问题，您需要先启动它。我们有专门的指南，其中包含您需要了解的所有内容，包括在Windows无法启动时或从命令提示符(Command Prompt)启动应用程序的方法：启动 Windows 内存诊断故障排除应用程序的 12 种方法(12 ways to start the Windows Memory Diagnostic troubleshooting app)。
从CMD启动Windows 内存诊断(Windows Memory Diagnostic)
如果您赶时间并且不想阅读其他指南，打开Windows 内存诊断(Windows Memory Diagnostic)应用程序的一种快速方法是搜索其名称(search for its name)，然后单击或点击相应的搜索结果。

步骤 2. 配置并运行Windows 内存诊断(Windows Memory Diagnostic)
当您打开Windows 内存诊断(Windows Memory Diagnostic)时，它会询问您是希望它现在重新启动您的 PC 并检查问题，还是在您下次启动计算机时扫描问题。如果您想立即解决问题，请选择第一个选项。
Windows 内存诊断
Windows 内存诊断(Windows Memory Diagnostic)会重新启动您的Windows计算机或设备，并在让我们想起旧的(Windows)MS-DOS操作系统的环境中全屏运行。默认情况下，它会在缓存打开的情况下运行两次标准(Standard)测试通过，然后自动重新启动。

如果要配置测试类型和运行次数，请按键盘上的F1 。您会看到可以配置的有关Windows 内存诊断(Windows Memory Diagnostics)工具的所有选项：使用的测试组合、缓存设置和通过计数。
Windows 内存诊断(Windows Memory Diagnostic)- 按您的方式设置
按键盘上的TAB浏览可用选项以更改以下项目：
- 测试组合(Test Mix)——在基本、标准(Basic, Standard)或扩展(Extended)诊断之间进行选择。尽管它们的描述有些技术性，但显而易见的是，执行的测试的复杂性和长度从Basic增长到Standard再到Extended。如果您想确保您的RAM(RAM)没有问题，扩展(Extended)测试可以完成这项工作，但测试持续时间会显着增加，从几分钟到几个小时。
- 缓存(Cache)- 您可以在Default、On或Off之间进行选择。我认为最好使用默认缓存设置而不是摆弄它。
- Pass Count – 输入您希望测试组合重复的次数。默认数字是两个，对于大多数人来说应该足够了。如果你要加倍努力，三遍应该提供足够的清晰度。
要应用您的设置，请按键盘上的F10并等待Windows 内存诊断程序(Windows Memory Diagnostic)运行。再次(Again)，用耐心武装自己，因为整个过程需要很多时间。完成后，该应用程序会自动重新启动您的计算机，并且您必须登录 Windows(sign in to Windows)。
步骤 3. 查看Windows 内存诊断的结果(Windows Memory Diagnostic)
登录Windows后，您可能会看到来自Windows 内存诊断(Windows Memory Diagnostic)的通知，告诉您是否检测到内存错误。不幸的是，此通知并不总是显示，您可能会在您的 PC 上错过它。

要查看RAM诊断结果，请打开事件查看器(Event Viewer)(open the Event Viewer)，然后转到“Windows Logs -> System.”在那里，在中间的列中查找将MemoryDiagnostics-Results提到为Source的事件。(Source)
在Event Viewer中，查找 MemoryDiagnostics-Results
单击(Click)这些事件，您会看到有关结果的详细信息，类似于下面的屏幕截图。如果您转到详细信息(Details)选项卡，您会看到有关每个测试通过的大量技术信息。

当您了解计算机上的RAM(RAM)是否存在问题后，请关闭Event Viewer。
Windows 内存诊断是否(Did Windows Memory Diagnostic)发现 PC 上的RAM存在问题？
不稳定(Flaky)或有故障的RAM可能会导致其他看似与内存无关的问题。手头有一个易于使用的诊断工具可以节省大量时间和麻烦（并且可能在不需要时打开您的计算机以重新安装内存 - 在那里，做到了！）。希望(Hopefully)Windows 内存诊断(Windows Memory Diagnostic)能够帮助您。如果没有，并且您需要第二个意见，请尝试免费的 Windows版 MemTest86(MemTest86)应用程序。
How to test your RAM with the Windows Memory Diagnostic tool -
RAM can cаuse some оf the most frustrating computer problems. Symptoms can be diverse and somewhat randоm: you may encounter high system instabilіty, data cоrruption, or unexplained behaviors that leave you pυzzled. When you haνe problems like these, it is a good idea to test the RΑM on your Windows computer. One way to do it is to use thе built-in Windows Memory Diagnostic app. It is available in Windows 10, as well as in older versions. Here is how to use it to troubleshoot memory problems and view diagnostic results:
Step 1. Start the Windows Memory Diagnostic tool
If you want to use the Windows Memory Diagnostic app for troubleshooting RAM problems, you need to start it first. We have a dedicated guide with everything you need to know, including ways to start the app when Windows doesn’t boot or from the Command Prompt: 12 ways to start the Windows Memory Diagnostic troubleshooting app.
Starting Windows Memory Diagnostic from CMD
If you are in a rush and don’t want to read another guide, a quick way to open the Windows Memory Diagnostic app is to search for its name and then click or tap on the appropriate search result.
Search for Windows Memory Diagnostic
Step 2. Configure and run Windows Memory Diagnostic
When you open Windows Memory Diagnostic, it asks whether you want it to restart your PC now and check for problems, or scan for problems the next time you start your computer. If you want to troubleshoot your issues right away, choose the first option.
Windows Memory Diagnostic
Windows Memory Diagnostic reboots your Windows computer or device and runs in full-screen, in an environment that reminds us of the old MS-DOS operating system. By default, it runs two Standard test passes with the cache turned on, and then it reboots automatically.

If you want to configure the type of tests and how many times they are run, press F1 on your keyboard. You see all the options that can be configured about the Windows Memory Diagnostics tool: the test mix used, the cache settings, and the pass count.
Windows Memory Diagnostic - set things your way
Navigate the available options by pressing TAB on your keyboard to change the following items:
- Test Mix – choose between Basic, Standard, or Extended diagnostics. Even though their description is somewhat technical, what is evident is that the complexity and length of the tests that get executed grows from Basic to Standard to Extended. If you want to be sure there is no problem with your RAM, the Extended test does the job, but the testing duration increases significantly, from a couple of minutes to several hours.
- Cache – you can choose between Default, On, or Off. I think it is best to use the default cache setting and not fiddle with it.
- Pass Count – type the number of times you want the test mix to be repeated. The default number is two, and it should be good enough for most people. If you’re going to go the extra mile, three passes should provide enough clarity.
To apply your settings, press F10 on your keyboard and wait for Windows Memory Diagnostic to run its course. Again, arm yourself with patience, as the whole process takes a lot of time. When done, the app reboots your computer automatically, and you have to sign in to Windows.
Step 3. See the results of the Windows Memory Diagnostic
After you log into Windows, you may see a notification from Windows Memory Diagnostic, telling you whether memory errors were detected or not. Unfortunately, this notification is not always shown, and you may miss it on your PC.

To see the results of your RAM diagnostics, open the Event Viewer, and go to “Windows Logs -> System.” There, look for events that have MemoryDiagnostics-Results mentioned as the Source in the column in the middle.
In Event Viewer, look for MemoryDiagnostics-Results
Click on those events, and you see details about the results you’ve got, similar to the screenshot below. If you go to the Details tab, you see lots of technical information about each test pass.
Event Viewer shows details about the Windows Memory Diagnostic
When you are done understanding whether you have problems with the RAM on your computer, close Event Viewer.
Did Windows Memory Diagnostic find problems with the RAM on your PC?
Flaky or faulty RAM can cause other problems that may not seem as though they are memory-related. Having one easy-to-use diagnostic tool on hand can save a lot of time and trouble (and possibly opening up your computer to reseat the memory when it isn’t necessary - been there, done that!). Hopefully, Windows Memory Diagnostic managed to help you out. If it didn’t and you want a second opinion, try the free MemTest86 app for Windows.
