I have Dell dimension 8400, 1.5 gb memory,160 gig HDD, and running XP Pro SP3. Of late my comptuer Fans have started to get louder at the start of programs but really loud during flash videos. I have installed HWmonitor but it only picks up the HDD temp. In the past and on other computers I have had to do a reinstall to stop the problem. Can anyone think of a way to solve this without a reinstall?
