PSU Buzzing sound?

post #1 of 4
Thread Starter 
Hi...

Over the past few months i've noticed a buzzing sound coming from my GPU. Just recently i opened up my pc and concluded that the sound was being emitted from the PSU. The effects of this is that when i load up a game or open a window, the pitch and volume of the sound will change. If i loaded a "call of duty" game, i would look at the floor and the pitch of the sound would be low; it would be a higher pitch if i looked up. My fps in the game would fluctuate alot, the game would skip frequently. I have no idea what this is all about as i am competent with PC hardware, but this has just baffled me. Any ideas on what i should do next?

Thanks

Yes the capacitors/transistors, things on the pcb are resonating and giving off noise. I had same thing happen to me quite a few years back on my Panasonic TV and their answer was to coat the pcb with wax which eventually suffocated some of these chips and killed off the TV.

Now with you it also sounds that these noises are an early warning for your PSU dying, so replace as soon as you can since you don't want it to take the rest of your computer with it.
