To check RAM health, use the built-in Windows Memory Diagnostic tool (search "mdsched.exe") for a quick scan or, for a deeper test, use specialized tools like MemTest86, as these diagnostics identify errors that can cause system instability, BSODs, or crashes, with results available in the Event Viewer after restarting.
Assuming you have Windows, you should be able to launch the Task Manager to see what percentage of your computer's RAM is currently in use. Just hold ctrl + alt + delete to open the Task Manager and view your computer's RAM usage. If it's above 60%, you may need to upgrade your computer with more RAM.
Open File Explorer and right-click on the drive you want to check. Select “Properties,” then go to the “Tools” tab. Under “Error checking,” click “Check” and follow the prompts. If issues are found, Windows will offer to scan and repair the drive.
Methods to Free Up RAM Instantly
One common method is to swap the memory modules between slots and see if the issue follows the module or remains with the slot. Additionally, you can use memory testing software to run comprehensive memory tests and find any errors associated with specific slots.
Some common signs include:
MemTest86 is the original, free, stand alone memory testing software for x86 and ARM computers. MemTest86 boots from a USB flash drive and tests the RAM in your computer for faults using a series of comprehensive algorithms and test patterns. your ram? Unreliable RAM can cause a multitude of problems.
One of the most common reasons to restart your computer is to clear the RAM cache.
To clean your RAM, you need to power off your computer, unplug it from the power source, and remove the RAM sticks from the motherboard. Then, use a soft cloth or a compressed air can to gently wipe or blow away any dust or dirt on the RAM stick and the slot.
70% RAM usage isn't inherently bad and can be normal, especially with many browser tabs or apps open, but it becomes a problem if your computer slows down significantly, indicating it's using slower disk storage (paging/swapping) for memory, which points to needing more RAM or closing background apps. High usage is fine if performance is smooth, but if you notice sluggishness, freezing, or crashes, then 70% might be too high for your system's capacity.
On your keyboard, select the Windows logo key + R to open the Run application function. Enter mdsched to open the Windows Memory Diagnostic app. In the Settings menu, enter memory in the search box in the left panel. Select Diagnose your computer's memory problems to access the Windows Memory Diagnostic app.
Under normal usage conditions, most SSDs will last anywhere from 5 to 10 years, and in many cases, even longer. They are capable of handling hundreds of terabytes of writes before showing signs of wear, and real-world tests often reveal performance well beyond manufacturer specifications.
Using the Command-Line Interface
Open the command prompt and type cmd in the search box. Click OK. Right-click cmd.exe in the search results and then select Run as Administrator. Type CHKDSK /f and press Enter.
Yes, 20GB of RAM is overkill for basic tasks like web browsing or office work, but it's great for heavy multitasking, demanding creative work (video editing, 3D modeling), and high-end gaming, offering smoother performance by preventing stutters and allowing for more programs to run simultaneously without slowdowns. While 16GB is standard for most gamers, 32GB is often the next step up for professionals, making 20GB a comfortable middle-ground, though some extremely intensive tasks might still benefit from 32GB or more.
Choosing between 16GB and 32GB of RAM comes down to your workload, future plans, and budget. For many users in 2025, 16GB remains the practical standard—it's more than capable of handling everyday tasks like web browsing, video streaming, office work, and even most modern games at high settings.
Signs It Might Be Time for More RAM
Methods to Clear RAM Cache on Windows
Wise Memory Optimizer is a free RAM cleaner and optimization tool for Windows systems. It helps you free up the In use of RAM, and empty the Standby memory to increase the Available memory, thus making your computer run faster.
Microsoft Edge
The fastest way to clear your cache is to use the following keyboard shortcut: CTRL + F5 or follow these steps: Check “Browsing History,” “Cookies and Saved Website Data,” “Cached Data & Files,” and “Tabs I've set aside or recently closed” Click the Clear button.
RAM is the main memory of a computer that stores the operating system, applications, and data, while Cache is a small amount of memory that is used to store frequently accessed data and instructions to speed up processing time. Cache memory is faster but has a smaller capacity than RAM, and it is more expensive.
What's the difference between clearing cache and clearing app data? Cache: Temporary files (images, scripts) that speed up app performance. App Data: Permanent user preferences/logins.
Bad memory modules within the RAM cause most RAM failures.
What happens when a bad sector is utilized is that the operating system or the BIOS can no longer maintain or initially boot the system. In both cases the RRAM will need to be isolated and replaced.
Overclocking RAM is generally safe if done within reasonable limits and with proper cooling. However, pushing voltage or frequency too far can lead to system instability, crashes, or even hardware damage if not monitored carefully.
