I keep noticing that this computer freezes for around a second from time to time. It's most noticable when playing games and movies. As there isn't any programs running that shouldn't be, I'm of the belief that there may be an issue with the drivers the USB wi-fi adapter we have uses. (i.e. they're rubbish )
To that end, is there any software around that will allow me to monitor the computer at a lower level, logging context switches, kernel-mode accesses, etc.?
