Well if you have a computer which has a high configuration but still performs slowly then most probably your computer is under a virus attack which hampers the normal functioning of the computer.
All you need to do: install an antivirus, get it updated from the internet, restart your computer in safe mode and run a virus scan. The antivirus scan will help eliminate all the possible viruses. Try uninstalling and reinstalling all the drivers of your computer, if the computer still functions in a slow manner then I would suggest that you get it checked by a proper expert.
You can also contact the outlet from where you purchased the computer and tell them about the problem; ask them to rectify it.
