This is not a beep while booting, just a random beep from inside my computer while it is running. Computer Specs: MSI P965 NeoF Mobo E6600 2gb Corsair XMS2 Ram 7950GT Seagate 500gb & WD Black 1gb Hard Drives Windows 7 64bit My computer runs completely fine otherwise. It is a single, short beep. It occurs maybe once every hour. My temperatures seem fine (cpu doesn't get hotter than about 50C under load). I've read that voltage variances can cause beeps like this, but mine seem decent: CPU Core 1.22 V +3.3 V 3.31 V +5 V 5.12 V +12 V 12.10 V +5 V Standby 5.02 V I've tested them under load and they don't seem to vary. I've been through my bios many times. Enabling and disabling things like smart fan has had no effect. I've disabled the beep service in windows, and nothing changed. I cannot seem to find a correlation between the beep and anything else. I hear beeps when my computer is idling with nothing running, as well as when I am doing more intensive activities like playing games. It does seem to occur more often when first starting programs, or browsing through files, but it may just be my imagination. Also, it does sound like there is a lot of hard drive activity when one occurs. Any help would be greatly appreciated. I've been trying to fix this for months.
