FS complete reset possible?

Is there a complete reset of the simulator? I would like to do without a de- and reinstallation!
The FS has an interruption every 10 seconds since the last update, meaning the image freezes for 3-4 seconds.
I have reinstalled graphics drivers, sound drivers, chipset drivers, Intel network drivers. Reset the graphics settings in the FS and in the Nvidia driver. Many times PC restarted, no improvement!
The DSL connection (110 MBit) is completely ok-
Within the FS is Vertical synxc with 60 FPS defined!

It is solved. I adapted some Values in my motherboard configuration.
Now is smooth and the FS runs without dropouts with 60 FPS
