Everything went well after I transferred all the parts from my Dell Inspiron 530s into a new case with a new psu/gpu except one thing: The PSU keeps making a constant buzzing sound.

This is kinda how it's been so far:

- In Guild Wars, having V-Sync off makes the buzzing pretty loud and makes the card activity reach up to 99% (as well as putting my framerate at about 120-130'ish fps in areas with low action). Having it turned on calms it alot but it's kinda still there. It stops almost completely when the game is minimized. On one rare occasion though, the buzzing was louder when the game was minimized. It also tends to change depending at what I'm looking at ingame.

- In UT3, the buzzing was there and somewhat loud as I navigate through menus. Ingame, it was much quieter but it was still making a quick buzz every 2 seconds and each time it did, the game stuttered. It was very frustrating. Yesterday when I opened the case to confirm that the buzzing was coming from the psu and not the gpu, I noticed that UT3 no longer had a buzz ingame anymore and was completely fine (except for the menus but that's ok). Not sure how that happened seeing as I didn't change anything. I did let the pc run for abit with the side cover off though.

- This seems to happen randomly but when I scroll up and down through menus outside a game, the psu will buzz along with it.

- The sound is definitely coming from the psu but starting up the pc without the gpu makes it dead silent.

- The card seems to be running cool most of the time, usually at 40-55c. Then again I've only really been playing GW/UT3.

The noise isn't loud enough to sound like somethin's seriously broken but it's still incredibly annoying at times. At first I was gonna try and deal with it but I almost can't - it's way too random. Some days it's not really there and other times it's constant.

I've tried a few random things to fix it but haven't really tried anything major yet. I'm actually considering RMA'ing either the psu or gpu but I'm not sure which to turn in. I'd definitely rather refund the gpu since having no psu would leave me without a pc to use, and I heard the RMA process can take long sometimes. Of course I could put the parts back into the Inspiron but that would be abit of a hassle.

Is there anything I can do about this?

Here's what I'm using:

Could you give a link to your PSU? There could be something wrong in the power transfer on one of the rails - if it's a multi-rail PSU - if that's the case you can plug the PCI-E connection for your graphics card into another slot. That might fix it.

Look if you can find a spare PSU to replace yours, maybe a friend can give you his for a day or so.

If the buzzing stops when you open the case the problem may simply be a matter of some part of the PSU being a bit loose and transmitting vibrations that resonate with your closed case. In that case you could try tightening the screws that hold the PSU in place or putting some heavy objects on top of your case or the PSU (that won't remove the cause of the buzzing, but it might change it to acceptable levels).

How do you know it's the PSU? Even in a small space like a PC enclosure it's surprising how loudly sounds can echo and sound like they're coming from somewhere else.

Anyway, it sounds like the noise is increasing/changing whenever the GPU is under load. Which yes could well be something wrong with the PSU when the GPU is drawing extra power, but could also be a number of things with the GPU such as the extra load increasing heat and the fan spinning up to compensate.

If it's the GPU it'll more than likely be the fan making the noise. If the fan socket on the card is accessible try disconnecting it then start the system and see if the buzzing is still there. I wouldn't suggest you do anything more than turn it on, listen and then turn it off because the GPU will overheat after a while without the fan; but if there's no buzzing noise then you know it's the fan, if it's still buzzing then it's most likely the PSU.

As FancyPants said, if it's a simple vibration rather than anything being wrong then generally tightening up screws might help.

Not sure how I forgot to link to those. Just updated my post.

The buzzing doesn't stop when it's open. I just noticed that when I started up UT3 after opening the case, the constant buzzing/stuttering that happened ingame stopped and still remains fixed with the case closed, which I don't understand. The prob was there for days before I did it. As for using another psu, I guess I could use the 250w from my 8 year old Dell. Of course that'd mean I'd have to remove the gpu too.

I opened the case and let the pc run with my ear right inside the case - it sounds like it's coming from the psu but I'll try running the gpu without the fan to double check.

Sounds like its GPU whine.

I had this same issue a while back with a different PC, but it was the HDD that buzzed (more like squeaked). It got louder while scrolling through menus and doing certain tasks which required a lot re-rendering the screen (not necessarily GPU/PSU intensive). I think it was a temp-related problem (CPU got up to 80C), and when I switched to a better-ventilated case, bot the temperatures and the majority of the squeaking went down to almost inaudible.

With my current PC, from time to time, slight buzzing comes through my headphones (using a PCI sound card). It seems to be related to mouse movement and scrolling as well. I have no idea what it is, but I do know that it has virtually no noticeable effect other than being an annoyance.
