Hello I have a hp ze2000 when I turn my computer on my fan runs at full speed and gradualy over a 10 sec period slows down til it stops. I have tried everything I can think of any help would be appriciated. The fallowing are steps I preformed to fix the problem: have updated the bios and then reverted the bios both flashed did not fix the problem. I replaced the fan, same problem. Any other subjestions??? One last note even when I have not booted up windows and only boot to the bios the fan still does the same thing.
