Hey. My Windows 8.1 64 bit has been acting up since I replaced my corrupted HDD. I have been getting random freezes, commonly when an action is performed. Example: Right clicking, downloading, opening programs, logging in. I noticed that my Disk Usage is in the high 90s in normal mode. Safe mode does not freeze for me, and disk usage is always 0-2%. I have to open Resource Manager because in Task Manager, Disk is not a viewed option in the Performance tab. CPU, RAM, and WiFi are both at normal usage %. Whats the issue here?
