I've got this strange problem with my old pc. Mobo is an a7v8x, 512MB RAM and two hard disks (Seagate 80GB & 160 GB). I'm not using a PC cabinet by the way. I keep hearing popping noises from my speaker when i watch videos on full screen mode/scroll web pages etc. I initially figured it was something wrong with my speakers, but found out that the same noises are also present when i use a head phone. I figured that moving the harddisks affected the noise.There are times when i absolutely get rid of all noises for some time by orienting the harddisk(s). Can anyone shed a light on this problem ?
