Let me ask, have you checked your Screen saver settings?
Could this possibly be a slide show setup in your screen saver?
I ask because of this:

They seem to appear only
after I leave the pc inactive for a while (like 30-60 minutes)

This seems to indicate your screen saver timing to me.

Gotcha.

HKCU\Control Panel\Desktop\Scrnsave.exe
Uncheck the Blinkx Beat entry.

Also according to your defrag log you are getting close to the 15% needed free space for windows and your MFT to run correctly.
Watch this carefully and maybe consider a larger OS drive to help with this issue.
If devper94's step isn't able to be done then
Right click on your Desktop and then click on Properties
Click on the Screensaver tab at the top of the window
In that window what is it showing the Screen Saver currently running to be?
If Blinkx Beat as indicated above then open the drop down box and choose a different one or (none).
Click Apply and then OK
Let us know if the issue stops then.

Re HKCU\Control Panel\Desktop\Scrnsave.exe ..... Please clarify meaning of HKCU; how do I call it?

Try my method and see if the results work. If not then if devper94 has not responded I will post the instructions on how to do his method.

About the HKCU: It's "HKEY_CURRENT_USER". It can be seen in Autoruns.

Changing the screensaver with Display Properties will likely work, but if it doesn't, then open Autoruns again. I am not on Windows right now, so I can't tell you the exact details, but let it complete the scan, then look for Blinkx Beat in HKCU\Control Panel\Desktop\Scrnsave.exe and uncheck it.
If you have any doubt, just ask us. We will sort out the problem for you.
