The mouse is often very jerky and unsmooth, sometimes the cursor freezes completely but the control is still there. I can move it to the corner of the screen and see the buttons light up (minimize, close etc) while the mouse cursor is still frozen elsewhere on the screen. It can also be slow to respond to typing taking a couple of seconds for every few letters. Another problem is that when im playing music it's broken up and stutters.
Also, my cpu usage seems to be a lot higher than i remember. Sometimes up to around 40% when just browsing the internet/files. And the cpu usage that it says in task manager often doesn't correspond with the processes running. For example the cpu usage of the processes listed can add up to about 10/20 but task manager wil say its 40 or 50%.
Im not entirely sure what the problem is. I've ran Ad-aware, AVG and Spy-bot which have all removed a couple of low risk items but the problem still remains.
Any Ideas? Thanks
