Funny static

Getting quite concerned about this, and after approximately 40 hits on the sound subforum I've had no suggestions at all, just hoping posting under general hardware might catch someone who's had this problem before:

Just finished assembling new PC two days back, but i get funny static on my headphones when:
-I'm scrolling in certain websites, but only certain websites, (such as this one)
-Playing certain games seems to cause static that changes pitch/volume depending on the colours being used by the screen.

Please don't tell my I've fritzed something.
I remember having this problem with another machine before, something to do with the way the system power was being distributed.

Using a wireless mouse, (if that's the reason behind scrolly webpage static)
Headphones are coming in on a line through my Cyborg V7 but am getting same problem when connecting to case front audio as well.

Any help is appreciated help

Power routing seems fine, I'll try and get an image up to see if we're in accord.
Is this the sole issue or could it be a sign of something a bit more sinister, just in case this doesn't work out.
 
agreed, i've known too often where people check all the complicated stuff first to find out they didn't switch it on at the wall or something
pictures just uploading to photobucket....just so i can get a second opinion.
i disconnected all the external audio leads and plugged my headphones straight into the rear panel, same problem, so i think its safe to assume the problem is occuring inside the case

hope you can see this clearly enough
front audio lead runs from front, past top fan and plugs in just underneath the bottom corner of the H60 radiator.
The 8 pin power is kinda close to it (one that dangles over the RAM)

(I know its not the best cable tidying in the world but it wasn't easy in this case)
 
i would give this a go but i'm 1/2way through copying a BIG file over LAN, so i'll do that when its finished.
Turning of wireless mouse (only wireless kit) did nought :(.
Thanks so far Dandos :D
 
i thought as much concerning the GPU, brighter colours (closer to white) produce a higher pitch than darker colours.
I'm using a DVI->VGA converter with a VGA cable, cos BenQ are cheap and only gave me VGA cable for a DVI monitor (unimpressed face), so i can't see that would be a problem.

strongest thing I've had the chance to run on here so far is BC2, and that made some interesting music :D. The 'noisiest' game so far for some reason is minecraft, and just on the main menu.
Will try removing the front audio cable as suggested by dandos in about 3hrs, when the copy is finished

yes, it has HDMI, can't really change the slot, cos the other x16 only runs at x4. Would disabling the sound to GPU be an OS side option or is that going to be in the BIOS? Becoming more convinced its got something to do with the GPU, as the interference is only occuring when doing something that needs the GPU to do a bit of work. (ie, games, and to a lesser extent scrolling php websites)

stulid magically strikes again, its reduced the volume of the static in games but hasn't eliminated it (naturally, as websites don't use VSync no improvement there), so i think we can agree the interference is GPU related.
Returning to the idea of moving the card, would it be feasible to run the the graphics card in a x16@x4 slot or would that throttle performance too much?

doesn't appear to be much in the CCC for controlling sound over HDMI, i will have a peak in the bios and see if i can disable sound to PCIe sockets from there after i've disconnected front audio (not likely to use it anyway).
I'll do that now, big file finsihed copying just now
@stulid, yes (don't judge me! :D)
just migrated to my laptop, so if anyone wants to suggest anything else before i start it up again, now would be nice

oh gawd, hope it wouldn't come to this, but it looks like it has, yes i can, but it wouldn't be a permanent resolution as the fastest the second socket can run is x4.
Also, by moving sockets would that confuse the drivers for a bit or anything like that? just so i'm aware.
PC is off now, so before we go for this any other ideas quickly?
 
i'll go ahead and do it, gimmie a few minutes and i'll get back to you.
Also, sudden remember, it didn't do this INITIALLY, only after the first few hours.
Don't know if that's enlightening or confusing but i'll let that sit with you
