before when doing normal tasks (such as surfing the web and using msn), my comp would use around 1.4gb of ram. but nowadays, its been slowly climbing and climbing, and it uses almost 2gb now! the fan seems to run high for menial tasks, and things seem a bit more sluggish. i haven't made any major software/hardware changes recently, and i'm pretty sure it isn't a virus (though it might be), and i checked task manager, and there doesn't appear to be anything in particular that's whoring out the ram. restarting the computer sets it back to usual for a bit, but then it climbs back up later. any thoughts? thanks in advance.
