Need some advice on this please.
I have a HP ProBook Windows 7 Pro (64bit) 4GB RAM laptop. Its less than 6 months old so kind of newish. In past few weeks the system has been stuttering randomly throughout the day, usually "pause" for a second then recover and work fine. No particular pattern and don't seem to be related to what I am doing with it. (I don't play resource draining video game).
The symptom includes :-
1. non responsive mouse (also happens to the mouse pad).
2. non responsive key-strokes (when typing the letters don't appear until half a second later).
3. when playing video (inc Youtube) it stutters regularly, usually within 5 secs interval. Sometimes the picture freezes but sound still playing, sometime its other way round, sometime everything freezes for a second or so. Imagine you sit and watch a 90 minutes movie....... :( Watching the same video on my other XP is fine.
I have so far defrag and cleanup but that didn't help. I read a lot of posts re this but nothing seems to work. I have the latest windows updates installed. If it was a driver issue what driver should I look at/reinstall?
Any more idea where shall I look at? Thank You.
