My computer randomly beeps (it always repeats 3 times 3 short beeps). I thought that it san be connected with overheating, but even when I've cleaned the computer (radiators even with compressed air, I've changed the thermal paste on the CPU) it still beeps. The temperatures while beeping aren't so high either - GPUShark shows 67 Celcius as the max, RealTemp - 58. The computer beeps only when I play some games, but, what's interesting, it didn't beep when I ran Furmark or Prime95, each for 30 minutes and the temperature was much higher then than now. My motherboard is MSI Z77AG43. Please help me, I've been trying to do everything to silence this annoying thing but after week I don't have any idea left what to do with this...
