Well I've been trying for ages to sort this problem out. My computer has been crashing repeatedly for a good while, it will all be running completely fine and then will suddenly crash. The pc just freezes and a loud crackling noise is emitted from the speakers, the sound is not a loop of the last sounds played, it just sounds like static. I suspect that it may be linked to audio or video as that has been the only time that it has crashed, playing music, watching videos or in FMV sequences in games.
I've tried reinstalling windows multiple times, replacing drivers and even updating the bios, completely run out of ideas. the computer has to be manually rebooted after it has crashed and I've been able to find no error logs in the event viewer that may relate to it.
Yea, that's probably what I'll try next, my understanding though was that ram failures normally resulted in a bsod, which I'm not getting at all. If they don't always though then I'll definitely be trying that very next.
Also happened when my PSU died on me. My pc kept on crashing when I tried to do anything demanding with the exact crackling sound. I would be easy on the restarting, at last all my USB ports, audio ports just everything got fried.
