Weird Lag

[ToddW2]

I noticed if I go to my download folder that has 320 files in it,and try to sort by largest it takes a good 5-10 seconds before it does this. While it's "thinking" my CPU fan increases in sound too, and then it's done and it slows a bit.

I've never noticed this on any of my other systems with SSD in the past.
This system has NO mechanical drives to spool up either.

What to check?

Disable the antivirus and see if the problem disappears.

You know that's a good point, I never ran an antivirus until recently!
