... is the noise my computer (graphics card?) seems to be making at regular intervals ;o It's probably worth noting before I begin that my old motherboard used to make similar noises and found out that it was a problem with the 'toroids' or something, in that if I pushed one of them with a pencil the noise would stop. Anyway, I got a new motherboard, and a new graphics card at the same time, but it's still making a similar noise: bzzzZzzZzztTtt! The recording above is from me just doing normal things in Windows such as minimising windows, or dragging an MSN window around the screen. Oddly, it doesn't seem to do it specifically whether it's under load or not, plenty of games (in fact, the majority of games) don't cause the noise at all, only a small handful of games and many desktop tasks seem to cause it. I'm using an Antec Sonata case with the default TruPower PSU, the motherboard is an Asus A7N8X-E Deluxe, and the graphics card is an Asus V9999 6800. One thing that does strike me as being out of place is the voltage reading from within SmartDoctor (which irritatingly resets the fan speed every time I turn on the PC, could it be related?), anyway, here's a screen shot: http://img136.imageshack.us/my.php?image=untitled1tm8.gif] Any advice or suggestions on what could be causing it and ways to fix it would be ace, thanks!
