Since my last Vista "update", about three weeks ago, I experience occasional lags in cursor movement and response, also in keyboard input. There's nothing common to the event and no warning of it occurring. I can be online, or typing, or playing a game, or the computer can be sitting there doing nothing (with just the desktop active), and suddenly moving the mouse gets no response for maybe ten seconds, when the cursor will instantly jump to the new position. Clicking anything also has a delay before any response. Typing produces nothing ...then half a sentence appears at once. The only thing I've found that clears this up is to restart windows; this irritant may recur ten minutes later or not for a couple of days.
It isn't a heat problem - CoreTemp shows about 40degC for each core, GPU-Z lists about 45 for the GPU. Task manager shows nothing amiss in processes or services. Reloading mouse software didn't help, nor did changing the mouse (from a Logitech to a Microsoft); changing from a USB to a PS2 keyboard didn't help. Avira, Malwarebytes, MSE, Spybot, and Ad-Aware all come up clean.
System is Vista Home Premium 32, SP2
