July 14, 201510 yr Have had two incidents recently where the sim (Prepar3d in this case) has frozen and a low tone comes from the speakers. The computer then needs to be rebooted. I was thinking this may be related to overheating but not sure. Will give my PC a good cleaning for starters though it doesn't seem too dirty...Any suggestions would be appreciated. Steve Giblin
July 14, 201510 yr If it was an overheating issue wouldn't it happen with any program running on your computer? Check your speaker connections and sound card drivers. If the speaker connections are plugged into the wrong ports on your sound card, you could hear noise from your speakers. Best regards, Jim Young | AVSIM Online! - Simming's Premier Resource!

If the speaker connections are plugged into the wrong ports on your sound card, you could hear noise from your speakers. Best regards, Depends what is overheating, and how intense other applications are. Install SpeedFan and check you're temperatures initially. Then go to the Graph tab and select some (not all) temperatures to monitor. Open P3D, use it for a while, check you're graphs. Of course, if you're computer freezes, you'll lose the data unless you enable Logging under Configure (although I've never done that) so try and check the temps before the computer freezes. That will at least give you a good idea on temps as an initial start Chris Smith
July 14, 201510 yr Author Thanks. I've done a thourough cleaning and am about to do a long haul test flight. Wasn't too dusty. It's just a strange scenario where whole computer locks.... Concerned that there may be a hardware failure in progress. Did a memory test last night and that tested ok.... Steve Giblin
July 14, 201510 yr Could be driver related, but overheating does cause stuff like this. Your PSU dying could also be related. It does cause weird issues. You can check by looking at your power rails, +5, +12 et al, and checking to see what your PSU is giving you for those rails. They should be as close as possible Chris Smith
