So you would think this is a easy thing to fix but ive tryed everything I can think of.
Things Ive thought of and done.
*Sound card/drivers: Ive reinstalled my soundblaster drivers and also tryed my ATI 6950 hd sound. Unpluged sound card boote only using ati sound. Alos muting all input.
*Windows or harddrives: Reinstalled windows and also tryed my old harddrive with a good working coppy of w7 installed (upgraded to ssd and havent used the old drive since).
*motherboard: bios reset and loaded with no overclocks.
*speekers: tryed 3 sets of speekers and 2 cables.
The only thing I havent mentioned is I had a problem with a pci-e device, my networkcard bigfoot 2100 seemed to be crashing out my pc and I couldnt uninstall the sorware so I did a well needed reinstall. It was after the reinstall I noticed the sound problem. A while after the reinstall I started getting crashing that pointed at my ati drivers. I did a sweap and installed older ones and the crashing stopped.
Im starting to belive its my motherboard as all my devices like sound card, network card and ati card all are pluged into pci-e ports.
I get distorted sound no matter what sound card I use. Even my old install of win7 on my old hard drive has the same problem so I dont belive it could be software.
If its my motherboard what sort of test can I do to prove this because this isnt even 3 months old.
