ASRock K7VM2 R3.0 I build a system for a friend around this board. I left it on 24/7 for a week, no problems. A month later, my friend says he hears a "siren" noise. I have not heard it myself as he does not live near me. The PC does not crash, but the siren noise is constant and annoying. I assume this is a temperature problem? Has anyone else experienced this on this board? Any ideas before I travel a long way to sort this out for him? Many, many thanks.
