Qosmio -- Loud Noise on Startup (Fan?)

Lately I'm noticing considerably loud (fan?) noise when I startup my computer --- it gets pretty loud as it goes through the various stages of the boot process --- but once it settles down (say after a few minutes after the computer has been fully booted and harddrive activity has slowed) --- the computer is fine and the noise level is back to normal. There aren't any noticeable noise issues (save perhaps when I pop in a graphics intensive game and then the fan noise starts up -- but I rarely play games nowadays) -- i.e. you can't tell there is a problem unless I need to reboot again.

I am assuming that I need to replace a fan or fans. If it isn't what is it?

Here is the key question: if I don't replace the fans, will it harm my computer in the long run? i.e. is this a problem i need to address ASAP?


Any help / guidance / insight would be greatly appreciated.

Thanks!

 

After reading this I tried to reboot and I did notice that upon starting up the fan would go full blast I guess at 100% for like a second then everything else would start up as well. I'm guessing that the notebook is just testing the hardware and so it tests the fan at startup? Maybe.

 

Yes the bios is a basic input output system. the computer gets the input, the component gives the output you could say. basically, it tests the hardware and performs simple, quick checks and makes sure that everything is working.

 

All toshiba's i've ever owned do that. It's normal.
