I have 16 GB of DDR4 memory, but Windows reports that around 15.8 GB is in use even when I don't have any obvious programs open. When I launch games, the memory becomes fully occupied and I start experiencing stuttering. Could this indicate malware, a driver problem, or something else? My system has a 13th-generation Intel Core i7-13700F and an NVIDIA RTX 4070. What should I check to find out what's consuming the RAM?

Check your Startup apps and temporarily disable anything nonessential, then reboot and see whether memory usage changes. It is also worth checking for memory-heavy browser tabs, launchers, overlays, and utilities running in the background. Windows using some RAM for caching is normal, but nearly all 16 GB being unavailable while idle and causing stuttering is worth investigating.
Outdated or faulty drivers can sometimes cause a memory leak, especially graphics, network, or chipset drivers. Update the NVIDIA driver, motherboard chipset drivers, and Windows, then restart the computer. If the usage keeps climbing over time, take note of which process or driver-related entry grows rather than assuming it is automatically malware.
Start with Task Manager. On the Processes tab, sort by Memory and check which programs are actually using the most RAM. Also look at the Performance > Memory section, since Windows may be counting cached or standby memory that can be released when another application needs it. If a process is genuinely consuming most of the memory, its name should point you toward the cause.
A normal idle system should leave a reasonable amount of memory available, even though Windows may show a large amount as cached. Use Task Manager to compare the total memory in use with the cached, available, and committed amounts. If the numbers don't add up, checking the Resource Monitor or using a memory diagnostic tool can help identify a leak.
