There is a known Memory leak bug that is fixed here:

Type Resource Monitor in Search, run it as Administrator, select Memory tab to see how RAM is apportioned.
Test the RAM overnight to stress it with the best bootable test memtest86, following this guide to test both sticks and slots:

Run Crucial System Scanner to check the RAM is properly spec'd and configured, what upgrade options exist for first quality RAM:

If the RAM maxes out while the CPU stays much lower I would add RAM to resolve this. You want your RAM used, but you need enough RAM to accommodate that.
Feel free to ask back any questions. If you'll report back results for each step, including in each link, it can help determine what else we need to try. I will stick with you until it is fixed.
