Thanks for the reply. by saying it slows down my pc i meant it makes me get low fps in games so i dont think it is related to storage devices. My windows and gpu drivers are up to date. Im not sure but i guess i have a ram related problem i have 16 gb ram installed but it only shows that i have 12 gb of ram and 11 gb of usable ram.
Nevertheless, i dont think 12 gb of ram would bottleneck my pc that much in games. Do you have any other ideas?
