My HD usage is almost constantly at 100% making my brand new laptop pause when typing every few seconds. Lenovo 530 I5 w/12GB RAM 2 months old I tried a clean retail install of windows 8 pro, and without any other installed programs problem existed. There is no program using more that 0.1mb/sec, its just usage. Tried clean retail install of windows 7 pro, and without any other installed programs problem existed. I did NOT notice this at all for the first month I had my new laptop. The only thing that ever makes it better, is if the HD is being constantly accessed by a program, such as defrag - while defrag is running, my computer never pauses and it runs smooth as it should. Any ideas? I tried Clean installs, turning off page file, turning off indexing. Not much is helping. Is it a HW issue? Thanks guys!
