Ok, the problem started about a week ago. I was on my computer surfing the net as usual, when all of a sudden my computer started making a loud humming noise, it would start off as a low noise.. then progress into a louder and louder one, then it would go back down again.. and then get loud, and so on. Now, sometimes it'll start making the noise for about 10 minutes, then go back to being silent(normal) as how it should be. I already cleaned it out using an air duster and got pretty much ALL the dust out of it, but it's STILL doing it. Does anyone have any advice on this? I mean, theres no dust in it, theres nothing blocking or touching it. The fan works fine, it spins obviously so I'm assuming it isn't broken, but I'm at a stump. I took it into the place I got my PC made and he advised to just clean it as it had ALOT of dust, but like I said, I already cleaned it and the noise still comes around every so often. Does this mean I'm going to have to replace it soon? And if so, what's a reliable power supply I should check into(brand, etc.) Many thanks. :tazz:

Well I can't believe you took it to the place that built it for you and they didn't clean and inspect it for you, it only takes a couple minutes.

This is not a good sign it may soon need replaced but first make sure it ain't loose in the case that could cause the noise ( can't believe they didn't at least check that) There are 4 screws in the rear of the pc case that hold the psu inplace

never open a psu itself, there are no user replaceable parts inside and they store voltage that can hurt you.

You would have to list your system specs for us to recommend a replacement.

Um, yeah.. I'll try that MrHunta :tazz:


Anyway, thanks for the reply Rick, and those were my thoughts exactly regarding the repair tech. But oh well. Now, I don't know what specs you need exactly, I'm guessing my processor would pretty much cover it?

2.40 gigahertz Intel Pentium 4 w/ HT
ST380023AS [Hard drive] (80.02 GB)
NVIDIA GeForce FX 5600
512 Megabytes RAM
Windows XP Professional SP2


I think that pretty much covers the important things? If theres anything else I should post let me know. I haven't gotten around to checking if it's lose or anything as it's quite late here and I'm just not up for it lol. But yeah, I'm guessing replacing it would be my best bet. Is that easily done manually or would I need 'professional' assistance? Anyway, I'm gonna make sure it's in there tight and double check to see if theres anything touching/blocking/bumping it. I'll post my results sometime tomorrow. Again, thanks for the reply.

Edit: Btw, the noise went from a fluctuating humming sound into a steady hum, still isn't as quiet as it was before but I guess that's a good sign. Still making the same noise though, just slightly quieter.

This Thermaltake is a pretty good one for the price and for a basic system. I have one of these on a machine it has very stable voltages, but if you plan future upgrades then



Antec 430W
Antec 480w
Any of these Enermax
Ulta X connect



I'm guessing replacing it would be my best bet. Is that easily done manually or would I need 'professional' assistance?



Seeing as this is a custom build (some brand name competers can be difficult because of tight cases)It is not hard if you are handy and take precautions for static electricity such as touching the case to discharge static before touching anything inside.

I suggest you open the case and have a look to see if you think you can handle it, if not take it to the shop.
