For a while now my laptop (a toshiba qosmio x770) has been running very slowly. I open something it takes quite a while to open it, usually if I'm watching a movie (not online) with either VLC or MPC it stutters sometimes till a point where even windows stops responding. Haven't tried running a game in ages as it started to be impossible, even football manager lags a lot although it used to run BF4 at high settings before.
Using the perfomance bar in task manager and another program I noticed my disk was running quite oddly, every second it changes from 0% to 100%, back to 0%, and always this loop, even if it is idle. Yesterday it was even impossible to open a movie file as it just completely stopped while opening.
Anything I can try to check if the problem is really the disk or anything else?
It has loads of space, wouldn't be because of that for sure as I cleaned it quite a lot.
Ccleaner is a must hve for me. In reality after I run it it gets a bit faster but not for long. Actually every time I open my laptop I kinda have to run both Ccleaner and Avast otherwise it barely works.
