I am using asus fx553vd-7700hq core i7 7th gen, 8gb ram but it works (booting, opening any software, heats up in multitasking, drivers are not compatible, etc) very slow than a normal i3+4gb laptop. I formatted it and again reinstalled OS (win10pro), then updated all the drivers but still I am unable to find peace in using it. The service engineer checked and said all the hardware parts are working fine. Now I don't have any solution.
Did you replace the hard drive? Slow systems that should run fast after a clean OS setup in my experience has some hard drive issues. get a solid state if you don't have it for the system, install Windows on that.
