with the high gpu usage and the changing to windows basic. it sounds like the (WEI) windows experience index is testing your system. windows will do this every so often when the computer idles or isnt doing anything gpu and cpu intensive. its normal. let it finish and everything should resolve itself. or goto task manager and kill the process. nothing to be scared about.
