If your computer crashes after installing a new set of RAMs, there are few possibilities. The first possibility is likely faulty RAM, the second possibility is hardware compatibility. More often than not if it is compatible due to overspec or underspec, your system will not boot up and will make a beeping sound.

😭 😍 😂 7 RAMDisk vs SSD – Ten Times Faster Read and Write Speed via RAM Virtual Disk

Faulty RAMs are pretty rare, almost unlikely if you bought a branded RAM such as Kingston, Samsung, Corsair, Apache and etc, this is because they performed many tests before distributing them to dealers. Based on my experience, here are some possibilities:

• Defective RAM ( Use both Windows Memory Diagnostics and Memtest86 to perform a deep scan, run twice to confirm, if both tests show the RAM is in good condition, then it is most definitely another issue. )
• Outdated Motherboard BIOS ( Update your Motherboard BIOS if it is outdated )
• Outdated drivers and chip-sets ( Update your drivers and chipsets )
• Overheating of RAM ( Use a table fan to test this )
• Faulty RAM slot ( Swap RAM between slots to see if problem continues )
• Incompatibility with your other hardware such as Asus NVidia GTX 970 Graphic Card. ( I’ve upgraded my RAM to 32GB from 16GB for my Dell XPS 8700, unfortunately, the solution to limit the RAM in Windows as shown in Reddit doesn’t work for me. Read more – GTX 970 unstable on system with 32 GB RAM or 64 GB RAM )

After much trial and error, swapping graphic cards and RAMs. I’ve discovered that my Asus Strix GTX 970 is unstable when my Dell XPS 8700 has a 32GB Kingston HyperX Fury or 24GB Kingston + Samsung RAM. It runs without problem when my system has both my old (4x4GB Samsung) and new (2x8GB Kingston) 16GB RAM installed, and with no problem when it is 32GB with my older GTX 745 graphic card. This is a very old issue, Nvidia appears to be dragging their feet or this is exclusively an Asus GTX970 problem.

↓ 01 – Windows Memory Diagnostics Tool | 17 Tests | Windows

This Window memory Diagnostics Tool is the Pre-installed memory testing software available in Microsoft Windows Vista, Window 7, Windows 8 or 8.1 & Windows 10. The Memory Diagnostics Tool will run automatically when you restart Windows. It might take several minutes for the tool to finish checking your computer’s memory.

Once the test is completed, Windows will restart automatically. If the tool detects errors, you should contact your computer manufacturer for information about fixing them, since memory errors usually indicate a problem with the memory chips in your computer or other hardware problem. Type “Mdsched” and search for the tool.

↓ 02 – Passmark MemTest86 | 13 Tests | Windows | Mac | Linux

MemTest86 is the original, free, stand alone memory testing software for x86 computers. MemTest86 boots from a USB flash drive or CD and tests the RAM in your computer for faults using a series of comprehensive algorithms and test patterns. The latest version of MemTest86 supports all the current technologies, including:

• DDR4 RAM (and DDR2 & DDR3) support
• XMP – high performance memory profiles
• UEFI – The new graphical standard for BIOS
• 64bit – From version 5, MemTest86 is native 64bit code
• ECC RAM – support for error-correcting code RAM
• Secure boot – With MemTest86 being code signed by Microsoft
• Graphical interface, mouse support and logging of results to disk
• Self booting off USB or CD, without needing DOS, Linux nor Windows
• Dual booting – Will boot to V4 in BIOS and V6 in UEFI from a single flash drive

↓ 03 – Rember | Unknown Tests | Mac

Rember is a front-end GUI to the ‘memtest’ command line memory testing program. This application will allow the user to select the number of test loops, as well as the amount of memory to test. There is a ‘Log’ tab that will allow the user to monitor memory testing. The user can toggle a ‘verbose’ switch to limit the amount of output, and can also choose to quit Finder and other applications.

Defective memory can cause computers to malfunction, crash, and behave in a variety of ways which can sometimes baffle end users and computer technicians alike. Apple provides hardware test CDs with most of their products, and there are some third-party utilities for macOS which perform memory testing.

In my experience, these tools have not always been able to quickly and efficiently diagnose memory problems. Rember has been designed to simplify the testing, and diagnosis of these problems.

↓ 04 – Apple Diagnostics (Apple Hardware Test) | Mac

Apple Diagnostics is a great way to check your Mac computer’s hardware. Apple Diagnostics helps to identify the potential source of a hardware issue and provides first steps to try and resolve it. Apple Diagnostics will also help you get in touch with Apple Support for further assistance.

What is 'Your computer is low on memory'?

'Your computer is low on memory' is a deceptive pop-up window displayed by rogue applications (e.g. adware, browser hijackers or other Potentially Unwanted Applications - PUAs). It is displayed by ScreenSaver.app, ScreenCapture.app, Spaces.app, MacSecurityPlus and other dubious apps.

The pop-up is designed to trick users into giving the application displaying it various permissions such as control over browsers and the data stored therein.

The text presented in the pop-up claims that the computer is low on memory and suggests that the user close some opened applications to free up memory. This pop-up hides another window, and thus the 'Close' button of the first window is also the consent option of the next pop-up.

Therefore, when 'Close' is clicked, users unintentionally click the hidden button as well. The disguised pop-up is a system window through which the rogue application displays requests to allow potentially harmful capabilities/actions. For example, in this deceptive manner, the app might request permission to control the browser (e.g. Google Chrome, Safari, etc.).

Once such access is allowed, the app behind this pop-up can gain access to documents and data stored on the browser, and then misuse it in various ways. Furthermore, 'Your computer is low on memory' is displayed when users attempt to uninstall the application displaying it.

Therefore, if you encounter this pop-up, you are strongly advised to immediately remove the app responsible for it.

Free Computer Memory Download

PUAs such as ScreenSaver.app, ScreenCapture.app, Spaces.app, and MacSecurityPlus display 'Your computer is low on memory'. These unwanted applications have various dangerous capabilities.

Adware-types display intrusive ads (e.g. pop-ups, banners, surveys, coupons, etc.), which significantly diminish the browsing experience by limiting browsing speed and website visibility. Additionally, when these ads are clicked, they redirect to sale-based, untrusted, compromised, deceptive/scam and malicious sites.

They can also be triggered (by clicking them) to download/install content (e.g. PUAs) without users' consent. Other unwanted apps called browser hijacker modify browsers, restrict or deny access to settings and promote fake search engines. Most PUAs (regardless of other capabilities) can track data.

They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather users' personal information derived from it (IP addresses, geolocations and other details). This collected data is shared with third parties (potentially, cyber criminals) seeking to generate revenue by misusing it.

To summarize, rogue apps can cause browser and system infiltration/infections, lead to serious privacy issues, financial loss and even identity theft. To ensure device and user safety, remove all suspicious applications and browser extensions/plug-ins immediately upon detection.

An example of a pop-up displayed due to rogue apps is '* will damage your computer. You should move it to the Trash.', which is caused by Helperamc, Hlpradc, Smbstrhlpr, Helpermcp and others. While unwanted applications do not need express user permission to infiltrate devices, they can also be promoted by various deceptive/scam web pages.

They are promoted as legitimate and useful software with a broad array of features, but despite how good these offers may sound, they are typically nonoperational. PUAs can cause serious problems. These apps are simply used to generate profit for the developers.

PUAs run intrusive advertisement campaigns, force-open all kinds of untrusted and malicious websites, hijack browsers and collect private data.

How did potentially unwanted applications install on my computer?

PUAs proliferate via the download/install set-ups of other software. The deceptive marketing method of pre-packing normal products with unwanted or malicious additions is called 'bundling'.

Rushing download/installation processes (e.g. skipping steps and sections, using pre-set options) endangers devices with potential infiltration and infections. Some PUAs have 'official' download pages. When clicked, intrusive ads can stealthily download/install PUAs.

How to avoid installation of potentially unwanted applications

All products should be researched before download/installation and/or purchase. Use only official and verified download channels. Download sources such as free file-hosting sites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders are untrusted and should be avoided.

When downloading/installing, you are advised to read the terms, explore available options, use the 'Custom/Advanced' options and opt-out of all additions (apps, tools, features and so on). Intrusive ads usually seem legitimate and harmless, however, they can redirect to dubious web pages (e.g. gambling, pornography, adult-dating and others).

If you encounter these advertisements/redirects, check the system and remove all suspect applications and/or browser extensions/plug-ins without delay. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.

Text presented in the pop-up window:

Your computer is low on memory.

To free up some memory, please close a few applications.

Screenshot of a rogue installation setup, promoting applications that display 'Your computer is low on memory' pop-up:

IMPORTANT NOTE! Most rogue applications are hidden deep within the system and do not appear on any list of installed software. Therefore, the removal process might be complicated. Taking the aforementioned ScreenCapture.app as an example:

1) Navigate to the '~/Library/Application Support/.screencapture/' directory, right-click on the 'ScreenCapture' application, and select 'Show Package Contents':

2) Navigate to the 'Contents/MacOS' directory and delete the 'ScreenCapture' application:

3) Once the previous steps are performed, the process associated with the ScreenCapture application will no longer be automatically re-started and you will be able to easily terminate it and remove the remaining application files:

4) After removing the ScreenCapture application, navigate to the '/Users/Test/Library/Application Support' directory and enable the display of hidden directories. Then, search for a directory with a dubious name (e.g., '.helper', '.dir', or similar), which contains an application called 'Finder'.

Once located, this entire directory must be deleted. Note that MacOS actually has a genuine Finder application. Yet, the malicious version has a completely different icon (typically, a Terminal logo) and criminals simply use this as a disguise:
