I have a Sony Vaio S series, which has been working splendidly up until about two weeks ago when every 30 seconds or so the computer would stutter for a bit. When playing a game, everything would freeze for a sec, then resume at triple speed until I was "caught up".
I played with driver updates, system restore, factory restore, tried both the intel GMA and the radeon graphics card, even booted into safe mode (this occurs when say typing in MS Word as well), and from the looks of it I think that my HDD is to blame. Response times in performance monitor are sometimes up to thousands of milliseconds for some processes and files.
HD Tune indicates a SMART warning for reallocated sector count (14) and 65 sector fails, which is not yet enough to trigger a SMART failure warning on POST.
Does anyone have any other ideas what this could be?
