About a week ago I took the side of my case off which is on the side of the motherboard. Ever since then when I truen my computer on it starts to make a loud whirring noise, I noticed that if I tap the side the motherboard is on reltively hard, the noise stopped. I turned it on when the case was off and found out it was the chipset fan that made the noise.
I put a new PSU in today. And now the whirring noise is even worse because if I hit the side of the case now, the noise goes away but then comes back. So I'm not turning my PC on now until it is fixed incase my system becomes more damaged.
What do you guys think I should do?
Help is much appreciated.
