I've a GA-P67A-UD4-B3 with an i5 2500K, 2x4GB RAM G.Skill Ripjaw series, an ATI Radeon 6950 and a PSU CoolerMaster GX650. The computer works ok most of the time, I have both linux and windows installed with dual boot.
But sometimes after being on for some time, the mobo small speaker makes three short (about half a second) beeps three times, like BEEP-BEEP-BEEP - pause - BEEP-BEEP-BEEP - pause - BEEP-BEEP-BEEP.
Until today nothing else happened, only the beeps, but today the 3 beeps repetitions started ocurring one after the other with a few seconds of pause between each 3 beeps, after about 15 seconds the computer turned off. I tried to turn it on, but it would just do a reboot loop. I disconnected it from the power for a while and then turned it back on, this time it started and the boot showed something like an update or rewrite fix.
Now the computer boots fine both linux and windows again, but it was turned on for about 10 minutes and I heard the 3 beeeps 3 times again, it didn't shutted it down but I did it to prevent it from happening.
My question is: What are these "3 beeps 3 times" are trying to tell me?
I tried googling about it but everything I found is about computers not booting, and 3 beeps meaning a video card problem. But my beeps are 3 beeps, 3 times. And my computer boots fine and video works just fine.
PS: The beeps appear both in linux and windows. On linux I've checked the CPU and GPU temperature, and they are both at 46 celcious (which is the room temp, we are in summer here) and according to the manuals it's safe temp. I read in another forum that gigabyte beeps only appear because of CPU temperature or FAN failure, but I don't think I have that problem. Also once the beeps happened if I restart the computer the beeps sometimes can be heard before booting into the OS.
