Hi I managed to record with my phone the noise, and freeze; Random Computer Freeze with Random Noise Loop - YouTube
which is here. (Near the end I turn up and down the volume with my speaker)
I don't know a great deal about computers on a technical level to please be gentle. Here are some details of what happens, my computer normally freezes/resets or crashes after 5 minutes after login, like clock work. Then it goes into windows recovery, which I boot up normally into Windows 7, then it sometimes will just freeze with the looped noise. Or sometimes it'll BSOD. But after that the computer is fine and runs like a dream, it's just the initial hump of turning on and warming up!? My system specs are here 'http://www.sevenforums.com/member.php?u=158950' because i've had the same problem before, as you can see by my posts. All my drivers are up to date, however my Nvidia won't update it says 'Unable to connect to NVIDIA. Try again later.' I'm on version 2.85.62 won GTX 460.
I hope that is enough to diagnose something, if not I can give you more information if you tell me how/where to get it...! There are no minidump files either!
Thanks for any help
