Laptop is extremely loud after restoring it

I haven't done any changes in the BIOS or in the motherboard. I did not use compressed air, it was just dust on the rails (where the air blows out), and I just removed it carefully with my fingers. There was barely dust there - but I'm pretty sure we're not looking at a problem related to dust, because this happened all of a sudden right after the restoring. Will it might help to restore the computer again? I will try what you said right away. Also, when I restored it I could choose to "Delete" or "Format" the disk, what should I choose there? :/

It was still noisy, but not a jet plane - noisy level kind of.

Let's cut the stages up in three pieces:

1. High sound
2. Even higher sound
3. Extremely high sound / blowing.

When I was in the BIOS, it's a mix between 1 and 2. But when using Photoshop, it's a mix between 2 and 3, sometimes it stays at 2 for a couple of seconds, and then number 3 keeps blowing up over and over again. It's hard to explain, but this isn't normal. I know that laptops are small and have tiny fans, but it shouldn't blow up so much just because I'm surfing on the web or doing my hobby (photoshop).

When you say "restore", are you talking about a Windows Restore Point, or the manufacturer's Recovery Utility, installing a Disk Image, or are you doing a Windows 7 clean installation?

Are these 'normal' sounds? Or are they something you never heard before?

They are "normal" fan sounds, but they are incredible high. I did a full system restore, you know with the Windows 7 disk. :)

With the Windows 7 disk you can do a clean installation - which doesn't restore anything - it installs a fresh, clean version on the hard disk.

Or you can do a System Repair - which will repair problems with an existing Windows installation.

Or you can find and Restore a System Restore Point - which simply loads a previous copy of the system registry.

But I am not aware of an option called "Full System Restore".

This may all sound trivial to you, but I am trying to understand exactly what you did that caused this problem, and I don't really know based on what you've told us so far. It's probably just semantics at play, so I'm just trying to get at what it is.

Very common cause of your problem is a dirty laptop fan. The reinstallation may have been just a coincidental connection.

Time for football. Later!

I have tried vacuum cleaner so many times, and it haven't helped at all. Like, really precise too! I might take it down to a 'support' shop they have here nearby, and they can remove all the dust. But should I try restoring my system from scratch again (incl. re-install windows). ?

If you have the time to do it that sounds like a reasonable plan. You would know for sure (I can't see anything from here!) but if you are sure that the re-install did it then maybe something went wrong.

If you do it, be sure to reset the BIOS defaults first, then set you SATA controller to AHCI if you got that, then reinstall Windows.

And that made another test occur to me: you could disconnect (remove) the hard drive and start the laptop. You will still be able to get into BIOS settings. Then you could see if the fans blow loud without any possibility of an OS affecting it.

You could even burn Linux UBUNTU to a CD and run it from the CD (Still no hard drive!) and see if it happens in a different OS.

I still believe that if the fan runs fast in BIOS then you are spinning your wheels playing with Windows.
But perhaps there is some initialization process that happens in an installation, or something you are doing in this "restore" process, that I am unaware of. So if you want to try it - go for it!

I just restored it, and now I'm installing all the drivers from the disc that was included with the laptop. But guess what, it's still very loud! How can I reset the BIOS settings? And how do I set my SATA controller to AHCI?
