Ah God damn it!
It's 3 AM here and I can hardly type :sleepy:

Anyway,
Just yesterday I started the computer in the morning and heard that loud sound, so I opened the case and checked it. The power supply fan was making that sound, it's like the fan is touching something while it's rotating which makes a very noisy thing. I have no idea why it started suddenly to make that sound. I opened the power supply itself and powered the pc on for a while to check it out (if you though I got shocked then you're right!), and the fan operated quietly!

However when I assembled all the stuff and powered-on I got that sound again?

What makes me really crazy is that I got assured that the fan is touching NOthing while rotating, but I am still hearing this sound ?!?!?!

So, did anybody had such a problem before, anybody got it resolved?!?!

HELP PLEASE!!
