I'm experiencing some slowness on my laptop (SSD, I7 4th gen, 16GB) lately. I can't really figure out what it is, but one thing that I noticed is that the memory usage is quite high (8GB of the 16GB), even when I'm doing nothing. So in this image it shows my memory (geheugen) usage:
I am using 856Mb (it was 400MB before I started typing this question in Chrome) , but 53% of my memory, so more than 8GB, is used. So I wonder: where did the rest go? There are no other users logged on, I run SqlServer but I already limited it's memory usage.
Also found this datasheet in process explorer:

These are the processes using > 10MB:
This shows 'hard errors'. Is this a problem?

Do you have any idea what it can be?
