Hey, i have a loud buzzing noise coming from inside my computer. Thinking it would be the fans i cleaned them but the sounds are still there and sound much quieter when i tap the top of my computer with my hand. What do you think is the issue here and how would i go about fixing it?

I've also just put a pencil in the gfx fan to stop it to see if it was coming from that. The sound stops along with it, so it definatly is the gfx fan. Even though i cleaned the fan so im still puzzled.

My system specs are as follows:

What brand/wattage PSU are you using.

If the sound is definitely coming from the PSU then I would recommend you get it replaced.

Definitely replace the PSU if that is the source of the noise. A PSU should be basically silent except for the sound coming from the cooling fan and that should be very subtle.

the psu is the power supply right?

I've just cleaned the inside of my PC so its dustless. But my power supply is making some very loud buzzing noises (sounds a bit like a lawnmower) It made buzzing noises before i cleaned it but not as bad. Now its constant. I've taken the power supply out of the computer and noticed some liquid coating on the back of it. Is this normal? Please help me fix the buzzing noise. Its only got worse after i cleaned it.

and if i have to replace it...how much are they? because I'm not working at the moment so I'm pretty skint.

ok i i got the power supply mixed up with the fan that connects to it. thought that the big fan was also the power supply. Clueless when it comes to computers. So ye. its the fan connected to the power supply that is making the noise.

Power supply voltage is 400w by the way. Fan speed is 1400rpm.

So when i tap the fan it stops the buzzing but then starts up again. Should i be worried that the pc will explode if its just the fan making the noise or?

Are you referring to the power supply fan. The fan/bearings could be worn.

I would suggest getting the replacing/upgrading the unit.

400W is a little on the low side for the HD 4800 Series graphics card.
