I recently installed Windows Live Essentials 2012 on my desktop computer, this was 2 days ago. After I had restarted my computer I noticed everything had slowed down drastically. Programs that I before could open in a few seconds took up to an hour to run. At first I thought it was Live Essentials that was causing this so I unistalled all of it's programs. This seemed to solve the problem for a while, but the next day my computer was slow again, just like it was when before.
I checked task manager, and my CPU remains at 0 - 5% as normal. Physical memory is at 21% currently. The LED light showing the disk drive symbol is on constantly. Every few seconds it will flicker and I can hear that disk drive working sound. If I am moving my cursor when this happens it will freeze for a moment.
So far I have tried doing a system restore in safe mode (I got the error saying system restore did not complete successfully when I tried out of safe mode) and defragmenting my disk drive. Neither have made a difference. If anyone could shed some light on what I should do that would be a great help.
