"Generator noise" on boot

"Generator noise" on boot Since I bought this computer, every time I boot up, I hear this weird noise. You could compare it to a generator generating energy, or kind of like a formula 1 car, it goes from soft to loud and then it ends with a click.

Based on your description, and this is just a guess, this could your hard disk starting to spin.

More that likely it's a fan. Bearings go bad / out and it'll sound like a rocket taking off. One thing to test if it's a bad fan is if you feel extra vibration.

I had a similar issue. During startup boot, it made huge generator like noise, and then slowly stopped after the desktop comes. My PC was almost a year old with AMD Radeon on-board and 4GB RAM. So I checked the CPU whether the fan was making noise or any wire was obstructing the fan etc. But nothing was there. Then I came to know that the SMPS was the culprit. I replaced it with a new one and Voila! The problem solved.
