hmmmmmm... she's virus scanned and defragged... yet sometimes, she's been weird. i turned it on before... and it sat there blankly, HDD light or whatever it is was on but not moving, monitor didn't come off stand-by. unplugged, rebooted, seemed quicker than usual. just after loading window screen (the one with the blue bar at the bottom of black page with logo), it gave a quick glimpse of the task bar against a grey screen, then loaded. is running fine... but noisy (constant "i'm busy!" noise) and has the occasional, "oh what did you press something, i'll take 5 minutes to process that bit of the sentence you're typing" moments. any ideas whizzkids??
