Ok, so I am running windows 8.1 64 bit and my pc has been running extremely slow for the last two weeks or so. I think I found the problem, my second hard drive is randomly spiking to 100% usage when it is not even in use. Open steam, boom its at 100% (steam is installed on a completely different hard drive) and I believe this problem is bogging my pc down. I tried doing some fixes like disabling superfetcher and windows search but that did nothing. What should I try? I doubt microsoft will do anything for me and this is making me regret buying windows.
