Hi !
I have a dell 5575 with ryzen 5 2500U and Vega 8 mobile gfx
Since the first day the laptop is extremely sluggish.Starting takes about 3-4 minutes in fast boot mode.
It cannot even play CoD4 .There are drops to 2 fps suddenly.Every tasks overheats the laptop so much that it shuts down even at 40% battery.I have reinstalled windows .I have anti virus installed.There are no viruses whatsoever.What can i do about it?
I bought the laptop for $800 from dell.
Will istalling ssd help.I have ordered nvme 1.3
Are nvme m.2 slots compatible with 1.2 and 1.3 version of nvme?
