Pop goes the speaker

[coltie]

Hi,
The system was custom assembled in a local factory ... Asus M4A785M with on board A/V hosting a XFX Radeon HD 5770 1GB 128-bit DDR5. O/S is Windows 7 Home 64 bit.

Since day 1 there has been an occasional electrical popping sound emitted from the left desktop speaker when opening a new window or application. I initially didn't pay this much mind because I'd seen it suggested in another forum that this popping sound was a supposedly harmless bi-product of the 64 bit OS.
Well..... three weeks and two frazzled speakers later, the not so innocuous 'pop' now has my full attention.

Tonight I discovered that their are two sets of audio drivers installed (on-board and ATI Catalyst) and suspect that a software conflict is the source of my troubles. The catch is I don't really want to sacrifice any more speakers through trial and error and could sure use some sage advice if anyone would be so kind.

Thanks

then..I would probably start by uninstalling the ATI driver and using the onboard sound. That may be your problem right there.

of course make sure you have a copy of the driver incase thats not the problem...

Is it random popping or a continuous faint beeeeeeeeeep noise?

Hi,
Thankyou for the replies.
Yea, it always happens when opening a new application or window but at random times. It's a short, abrupt, electrical "zot" always on the left speaker and it's fried two different speakers. It hasn't happened with the headphones.
Pursuing the software conflict angle I disabled the ATI audio drivers and am about to hook up a new set of speakers (victim # 3?) for a test drive.
