Hi, I have Windows 8.1 as my operating system. After a random amount of time, my Disk usage will jump to 100% for around 30s-1min then go back to normal. It will continually do this over and over again. The problem is, I can't figure out a solution or the cause of the problem. I looked online for a solution. I found a possiblbe workaround of increasing my Virtual Memory but this made the problem worse as it took around 5x longer to boot then it hung on 100% until I turned it off, back on again and changed the VM back to normal. Earlier this month, I decided to run a full test on my HDD's using anti-virus software, and it came with a positive result, no problem/virus's/malware found. From here the problem persisted, so I continued to look for answers. I then tried to run a Disk scan through command promp which ,unsurprisingly, didn't go well. My computer was stuck in a loop of attempting repair and then restarting to do the same thing again. it continuesly got stuck on 11% complete every time it attmpted repair. I ahve put my system back to normal back then and it's been doing it's ussual Disk 100% then back down to normal routine. The only other clue is HDD Corruption but im not sure how to solve this. Or it could be something else.
