Every few days of uptime the memory usage of my PC increases without any obvious reason. Here is a typical memory usage reading after 4 days of uptime:
However, I've tried to trace the offending application causing any potential memory leaks. Task Manager lists the highest app usage from Google Chrome (with only ~200MB usage):
Closing other apps still leaves 62% mysteriously in use:
Proc tags are listed using high amounts of memory in the Paged and Nonpaged pools, respectively:
Strangely, restarting the PC clears up memory usage, but shutting down and starting up doesn't. I assume this is due to the "fast startup" feature, but I'm not sure why it would affect memory usage.
If it matters, I am also using CleanMem as I assumed it would help alleviate any memory leak problems.
Given these, how could I pinpoint what is causing high memory usage in my system?
UPDATE: I tried to run xperf to view stack traces on the pool tags, as suggested in a comment, but I am not sure what to make of what I have found:
