Hi. Just signed up hoping someone could give me some advice. First of all here is a brief info of my system e8400 gigabyte EP35-DS3R hd4850 Vista home premium 64bit. This is the symptom Every once in a while, no matter what I do(gaming, listening music, wathing movie, etc.), the sound starts to repeat itself over and over. Also the system tends to respond little bit slower when this happens. Once this happens it persists until I restart the system. I tried bios flashing, updating drivers(sound, inf, video, lan...you tell me), but the problem still there. I constantly keep my eye on the temps so I know it doesn't have anything to do with overheating. Any suggestions? Thanks in advance.
