So i've been having about 50% ich of my ram being used by nothing for around 2 months now and i can't seem to fix it, i have aleady disabled superfetch an enabled it multiple times, swapped the memory sticks but i can't fix the problem, also i can't update windows, every time it finishes updating a message pops up saying that it couldn't complete the updates. i think it has something to do with the boot drive but idk.
my specs are:
i5 6500
g1 sniper b7
2x8 hyper x fury ddr4 2133
gtx 1070 zotac amp extreme
corsair cx600
generic 500gb hdd (boot-drive)
toshiba 2tb hdd
