1 week ago I purchased this Asus X540UP-DM020T 15.6" i7 (7th Gen) 1TB 4G Ram 2G Vram AMD Radeon R5 laptop. It is so slow and my old laptop i5 is still faster that this new one. I tried to return this back to my seller because of the freezing issue. I haven't installed any apps yet, or software, but the unit is already freezing. The hard disk usage is always 100%, though no apps are running. Any ideas about this guy? How can I let it speed up?
