Hi there, I've recently built a new comp for audio work and everything is finally working except my now I can hear a strange garbled audio noise through my speakers once booted into windows. There is a constant ticking or whirring noise and when I move the mouse a I get a sound similar to a dial up modem noise. Halfway between a screech and a scrape. Things I have tried: Isolating the mobo and all the components from the case placing the mobo on an anti static bag and then a card box. Updating Bios, soundcard drivers and graphics card drivers. I've also tried using the onboard sound and this produces the same results. I've also tested the soundcard, video card, PSU, and HDD in my old computer and booting from the same HDD produces no unwanted noises what so ever, the only things I can't test are the CPU, RAM and obviously the mobo itself. I'm going a bit insane over this after about 8 phone calls to the retailer and numerous emails to gigabayte who don't seem to understand the problem. I have no way of testing the CPU but I can't see it being the cause of the problem Anyone's thoughts on this would be more than welcome. I even considered asking PC world (the only computer shop near me) for help, that's how desperate I'm getting. Here's the spec: Gigabyte EX58-UD5 Mobo Intel i7 920 Noctua CPU cooler 12 OCZ Ram 1600MHz ATI Radeon 4670 Graphics card (passive) EMU 1820 Soundcard + Breakout Box Be Quiet Dark Power Pro 650w PSU Sony DVD rw Optical Drive Western Digital system drive Samsung audio drive Seagate video drive Hope that's enough info for now and like I say if anyone can help please let me know as I meant to starting work on a friends music project soon. Regards, Will.
