内存使用率达到 100%，超过 10gb

Question

我的 PC（Win7 x64）目前有些问题。时不时地，我的 PC 会完全冻结几秒钟/几分钟，然后慢慢恢复正常。我注意到 RAM 使用率可能是问题所在，因为任务管理器显示我的 12GB RAM 在机器冻结前后不久就被使用了 100%。但是，当我检查时，进程本身并没有使用太多。Chrome 使用了 1GB，没有其他进程使用更多。

我尝试使用 perfmon 监控问题以找出究竟是什么使用了所有 RAM，但是由于 PC 冻结，应用程序无法正确监控值。

您知道什么应用程序可以帮助我找到这个问题的根源吗？或者之前有人遇到过类似的问题吗？

提前致谢。
