machine is running both ubuntu and windows and the issue is still exsisting. ubuntu dont want sometimes boot if any of sound cards is in use .
in desperate act i deleted ubuntu and run only windows. i noticed one thing -- when i put whole computer with opened box into opened window all temperatures go down because its cold at nights - sound is playing longer time. howewer i found the elements R20 2R1 or something they might be coils , they alwasy were warm but they are not reason as were replaced.
i have did disable azalia codec in bios and started to use pci sound card - sound still keep go away. i try update drivers but no effect
i noted another thing , when i try use drivers for network card from my gigabyte CD, network goes crazy connections are lost timed out , huge ping rates . when i use windiws built-in network drivers all is working fine . same for pci network card. cannot use cd drivers .
i try do same for azalia codec - use built-in windows drivers but no way sound goes away.. windows has no drivers for soundblaster..
finally sound still goes away. cant use azalia codec and pci card. also sound is disappearing when using usb sound card , anyway computer hang up often if any of sound-cards is online. hanup signs is hard disk bulb lighting at max power of light , mouse cursor goes rotating wheel windows refuse to execut ctrl-alt-delete finally mouse stop to ever move and only reset button helps. if i disable both sound cards computer still hang up but in about 8 - 10 hours...
i contacted the gigabyte tech support and they recommend buy new gigabyte motherboard. they refuse to RMA as varranty is long time over and repair is pointless.
i am decided to repair it because no funds for new one .
