A week ago I did a completely fresh install of Windows 8 64 bit and everything was working great. When I booted up my laptop on Wednesday I noticed it was running terribly slow. When I opened task manager I saw that disk usage was at 100% despite the combined total of data transfer being 0.8MB/s.
The problem occurs constantly if I set my laptop power mode to balanced but only occurs intermittently at high performance. I've run a chkdsk and everything is showing up fine and bizarrely there is no slowdown whatsoever on safe mode.
Any idea what I may have done wrong?
