An XDA Developers writer investigated a Windows PC that regularly used more than 80% of its 16GB of RAM and froze during routine work. Task Manager showed only part of the picture; Process Explorer, Resource Monitor and Brave’s built-in task manager helped identify ordinary system activity and a memory-heavy browser tab, not malware.
An XDA Developers writer says Process Explorer, Windows Resource Monitor and Brave’s task manager helped investigate a PC that repeatedly used more than 80% of its 16GB of RAM and froze during routine work. The account found no malicious process; the browser, including a content-management tab using about 1GB of memory, was the main concern.
The writer began investigating after Command Palette, a PowerToys utility, displayed system resource use. The high memory figure coincided with freezes when opening documents in LibreOffice and running Docker Desktop, tasks that had previously worked normally. The writer says the PC had about 2GB of hardware-reserved memory, so not all of its 16GB was available to applications.
Task Manager identified the browser as the largest memory user among the processes it highlighted. But the writer’s estimate of the heaviest applications added up to only about 6GB, leaving the overall usage unexplained. Task Manager also did not make it clear which browser tabs were consuming the most memory.
Process Explorer, a Microsoft Sysinternals utility, offered another view of running processes and let the writer search online for information about them. Resource Monitor, built into Windows, showed memory categories including In Use, Standby, Free and Hardware Reserved. Together, those tools helped identify Windows Resume as an unnecessary source of some memory use, but the writer says it was not a major contributor. Brave’s task manager then showed the memory footprint of individual tabs and extensions; one CMS tab used about 1GB.
Why Is My PC Using So Much RAM?
An XDA Developers writer investigated a PC that repeatedly crossed 80% of 16GB RAM and froze during everyday work. A closer look revealed a more useful story than the headline percentage: system activity, reserved memory, and one demanding browser tab.
Four views, each answering a different question
Task Manager started the search. Other tools helped explain the memory categories, inspect processes, and pinpoint an individual tab.
Task Manager
Showed the browser as a major user, but the highlighted applications added to only about 6GB and did not explain the overall reading.
Process Explorer
Microsoft Sysinternals utility offered another process view and a way to look up unfamiliar processes online.
Resource Monitor
Built into Windows; clarified In Use, Standby, Free, and Hardware Reserved memory.
Brave Task Manager
Separated tabs and extensions. One content-management tab used about 1GB of memory.
PowerToys Command Palette
Displayed system resource use and prompted the writer to investigate the sustained high reading.
No malware found
The reported checks pointed to normal system activity and browser use, not a malicious process.
Follow the evidence, from system to tab
High use alone does not prove a fault. In this report, freezes during routine work made it useful to find where memory pressure was coming from.
Notice the pattern
Command Palette showed use above 80%; freezes appeared while opening LibreOffice documents and running Docker Desktop.
Check the overview
Task Manager identified major applications but left a gap between the listed processes and total usage.
Compare system views
Process Explorer and Resource Monitor added process detail and memory categories. Some use came from ordinary Windows activity.
Inspect the browser
Brave’s task manager surfaced a CMS tab near 1GB. After trimming some use, reported memory fell into the 70% range.
What the report measured—and what it did not
These figures describe one user’s investigation, not a controlled test or a diagnosis for every Windows PC.
Interpretation: The report does not give an exact later reading, a complete process-by-process breakdown, or the amount of memory freed by each change. It also does not establish that the browser tab caused the freezes or confirm that they stopped.
Check tabs before adding memory
Use a specific, observable change to narrow the search. The account offers a sequence, not a guaranteed fix.
Open its built-in task manager
Choose Menu → More tools → Task manager, or press Shift + Esc. Compare tabs and extensions, then close or reload a heavy item and observe whether performance changes.
High RAM use is a clue, not a verdict
Windows uses available memory, and hardware-reserved capacity affects what applications can use. Recurring freezes may need further troubleshooting beyond memory readings.
What readers should take away
The value of multiple views is that each narrows a different part of the question.
Which tools were used?
Task Manager, Process Explorer, Resource Monitor, and Brave’s built-in task manager.
Did the investigation find malware?
No. The writer reported normal system apps. That finding applies to this PC only.
Does high use automatically mean something is wrong?
No. The investigation began because high use coincided with freezes during routine work.
What remains unknown?
The exact final reading, the benefit of each change, whether freezes stopped, and whether one tab caused them.
Finding the Memory Behind the Freeze
High RAM use alone does not establish that a PC has a fault: Windows and applications use available memory, and the total includes hardware-reserved capacity. But in this account, high usage coincided with freezes during everyday tasks, making it useful to identify which processes were responsible rather than relying on the headline percentage.
The report illustrates why a single summary in Task Manager may not answer every troubleshooting question. Windows’ built-in Resource Monitor can clarify how memory is categorized, while Process Explorer offers a different process view. A browser’s own task manager can narrow the search to a specific tab or extension. These views helped the writer distinguish ordinary system activity from the main source of pressure and trim some unnecessary use.
The account is one user’s investigation, not a controlled test or a diagnosis that applies to every Windows PC. Still, it offers a practical sequence for readers experiencing similar symptoms: examine system processes, compare memory categories, and inspect browser tabs before concluding that a high reading indicates malware or a failing computer.

How the Investigation Unfolded
The investigation started when Command Palette displayed resource use after the writer enabled PowerToys utilities. The reading stayed above 80% of 16GB, and the PC began freezing during work. The writer first used Task Manager, a familiar tool for checking running applications, but found that the processes it highlighted did not account for the apparent total.
The writer then checked Process Explorer and Resource Monitor. Both showed processes and memory information in different formats. The investigation did not find malware; it instead pointed toward normal Windows activity and the browser. After closing or reducing some unnecessary apps and features, the writer says memory use returned to the 70% range. The browser remained the main target for further checks, leading to Brave’s per-tab task manager.
The source account names Brave and its menu path: open the hamburger menu, choose More tools, then Task manager. It also gives the shortcut Shift + Esc. The browser view can separate tabs and extensions from browser processes and other tasks, helping show why the number of open tabs alone may not predict memory use.
““I was consistently using over 80% of its 16GB RAM capacity — and I couldn’t quite figure out what was using everything up.””
— Megan, an XDA Developers software writer
What the Memory Readings Cannot Show
The source does not provide a full process-by-process memory breakdown, screenshots, or measurements before and after each change. It says the writer returned to the 70% range after trimming some use, but does not give an exact later reading or quantify how much each action freed. The report also does not establish that the browser tab alone caused the freezes.
No malware was found in the writer’s checks, but that is a report about this particular PC, not evidence that high RAM use on other computers is harmless. The account does not identify the PC’s full hardware configuration, Windows version, browser version, or how long the elevated readings persisted. It also does not say whether the freezes stopped completely after the changes.
Check Tabs Before Adding Memory
For readers with similar symptoms, the reported next step is to inspect memory at more than one level: use Task Manager for an initial overview, Resource Monitor for memory categories, and Process Explorer for additional process detail. If the browser stands out, its built-in task manager can show which tabs or extensions use the most memory. Close or reload a specific heavy tab and observe whether performance changes, rather than assuming every open tab has the same effect.
The XDA account does not report a further test or a final hardware change. Whether the writer’s PC continued to freeze, and whether the same tools would identify the cause on another system, remain unanswered. Any recurring freezes may require further troubleshooting beyond memory readings, since the source does not establish a single cause for all of the symptoms.
Key Questions
What tools did the writer use to investigate high RAM use?
The writer used Task Manager, Process Explorer, Resource Monitor and Brave’s built-in task manager. The latter tools provided different views of processes, memory categories and individual browser tabs.
Did the investigation find malware?
No. The writer says Process Explorer and Resource Monitor revealed normal system apps rather than malicious processes. That finding applies to this reported investigation, not to every PC with high memory use.
How do you open Brave’s task manager?
In Brave, select the hamburger menu, then More tools and Task manager. The source also lists Shift + Esc as a shortcut.
Does high RAM use automatically mean something is wrong?
No. The report notes that RAM use by itself is not necessarily a problem. In this case, the writer investigated because elevated use came with freezes during routine work.
What remains unknown about the reported PC?
The account does not provide an exact final RAM reading, quantify the benefit of each change, or confirm whether the freezes stopped. It also does not establish that one browser tab caused all of the performance problems.
