100% CPU usage even at idle. Help

in New Users
I recently installed DAZ3D 4.10 64bit and was following guided tour. CPU usage spiked 100% and I have tried closing the app and re-launching multiple times but it just starts using 100% of CPU as soon as it starts.
I took some screens if that might help.
System config - Xeon 1231 v3, 8gb ram, GTX 750ti 2gb, 250gb SSD.

The last screenshot indicates that you are using nVidia Iray preview mode (the I in a box icon at top-right, next to the exposure icon). If you don't want that click the icon and select another preview mode.
Thanks I switched it, now its back to normal.
I also found under render settings only CPU was active, now utilising both GPU and CPU
Thanks for the help
