My computer has slowly started to have a cackle sort of sound coming out of any audio port. It started where it would do it now and again but then go. Then it progressed to every time i turn it on but would fade after playing some audio for a while. To now doing it all the time without fail cannot get rid of it you can hear the audio its trying to play but its all distorted and cackling sometimes it fades a small amount so you can hear it a bit better but never enough to make the computer useable,
Any help or advice would be amazing ive ordered a external sound card as i think that may be the problem the sound card on the motherboard
many thanks to any replies
