Stange Noises

Hi,

I have just built a new system with the following spec:

3.4GHz P4
Gigabyte GA-8I875 Ultra Mobo
2GB Kingston DDR400 RAM
160GB Seagate Barracuda SATA 150 HDD
Gigabyte Geforce FX 5950 Ultra
SuperFlower 550W PSU (Quad fan)
Thermaltake Xaser III Tower Case

Whenever the system is under load, for example in a hectic game
segment, or using Windows, inparticular scrolling vertically in
Internet Explorer, I get a sort of chattering/ticking sound. At first
I thought it was one of the cooling fans, so I ran the system with
them all switched off (except the CPU+PSU) and the noise was still
present. I don't think its the HDD as on listening to the board while
the noise is present, it appears to come from the area housing the
RAM. Could it be the memory? Its currently running at 400MHz
dual-channel, I have tried lowering the memory clock-speed and this
didn't help. Could it be the fact it's dual-channel?

Any help would be greatly appreciated.

Cheers,

Paul B

Likely the PSU, especially when you mention the noise appears under load.
Check the CPU fan and heatsink for a good mechanical connection. Fan on the
video card ?

Memory does't make noise of any sort.

Had another user claiming they heard ticking noises from their power
supply when scrolling. Not likely. More likely their ear isn't as
directional as they think. Have you tried disconnecting both the
external speakers from the output jacks and also the internal speaker
from the motherboard? Are there any other internal speakers, like on an
internal modem? If so, disable or disconnect them or remove the card
that has them.
 
Thanks for the suggestions people, I'll have a look and see if the
internal speaker is connected and have another look at the PSU and
mechanical connections.

Over the last few days I have been leaving eMule downloading
overnight. When I do this the noise occurs intermittently (every 10-20
seconds). I don't think that eMule is particularly processor or memory
intensive, but might that timepsan coincide with writes to the
harddrive by the program? Maybe its a hardrive issue...

To follow-up my previous post, I have noticed that the chattering
noise happens in Internet Explorer when viewing a long webpage ONLY
when I scroll using the mousewheel of my USB Intellimouse Explorer,
NOT when I use the vertical scrollbar to drag the page up and down.

Strange or what?

I've had the same problem in the past, but I can't remember what it
was. I believe the noise was comming from the speakers though.

Having trawled various hardware forums for this problem, it would
appear that it is being caused by the graphics card. This is a known
issue with the GFFX 5950 Ultra, but as of yet there is no fix.

Thanks for all your help.
