Hi, On one very hot day, the room containing my computer was very hot and so, my computer was very hot, I did kind of a dumbass thing and removed one of the side panels and got a fan blowing into the case to cool it down. When I turned off the fan, I noticed that my power supply fan was making a very loud noise, it sounded like a petrol generator or something. So, I turned off the power, removed the PSU fan grill and wiggled the fan about and it went quiet again. The problem is, now, it just randomly starts making the generator noise like a very loud grinding sound. It does go quiet after I pull it around a bit, but if I ever jolt the PC when im moving it, or lay it on it's side to remove stuff, when I turn the PC back on, the PSU fan starts that really loud grinding noise again and its annoying cos I have to keep powering up then powering down then moving the fan around until it stops grinding. I'm not sure what is up with it, or what I could do to fix it so it doesn't grind again. any ideas?
