Seeing as how Pc advisor is always helpful here we go again Receently my Medion PC P4 266 GHZ (around 4 years old) has started occassionally running noisy as if there is something blowing or reverberating The pc continues to run ok and just sounds bad but obviously something is afoot If i lift the case uo and slightly "jolt it" the noise quietens also the noise is not always present but seems to happen after use I have had the side off cleaned the fan area which seems to be working fine and also lifted the fan unit out and re-seated everything The noise seems to be coming from a what i guess is the power supply unit (box) I have also undone this and cleaned the vents I noticed there is something written on the side of the power unit "kill noise" and am wondering if the power supply has a "quietening " device within Any advice is appreciated so thanks in advance i would like to know if power supply units are costly and can be easily fitted to Medion pc's Regards
mrtreacle Hi, I had a similar problem last year. Occasional noise and I was doing the same as you, giving the case a bit of GBH. It turned out to be that one of the case fans was on the way out, the bearing was knackered so I replaced the fan only about £5ish. Problem solved.
