so far no viruses/malware, I am pretty sure the sleep option is not on because I did changes about sleep/hibernation and disabled them to maximise SSD.
Anyway is this the same as when my HDD's shut off when they are not in used for a while? Sometimes when I get back, my HDD will turn off when not in used I have 5 HDD + an SSD. And usually when they are off, and I try to open my computer or open a file from 1 of the HDD, the HDD won't show on the list and usually the window will be showing as loading with the green bar and it takes forever to finish and can't open the files till then.
tested my memory with memtest and windows diagnostic tool and seems to be all alright. Will update again regarding the HDD turning off.
