How Do I See What Programs are Using My RAM?

Question

At the most ridiculous of times during the day, my RAM usage will suddenly spike from 30% to 99% and freeze my PC. Malware programs see nothing, and no sign of hardware issues. I want to know what's stealing all of my resources to cause this.

Note: I am not getting any errors, no corrupt files, no blue screen, no kernel errors, no BIOS warnings. It just freezes, stops, then I reset PC, and everything is fine again (until it repeats at some random time).

Answer 1

RAMMap is the tool to see the memory usage in Windows. My link points to a Microsoft Blog post which explains what the values mean.
