Hello, my computer is a pre-build computer with Intel Core i5 CPU, 4 GB of ram and is a 64 bit operating system. Every hour or so, the computer turns off, then turns back on only to make a couple of beeping noises (They were too fast for me to count them) and then turn back off only to turn back on as if the computer was to turn on if I pressed the power button, I could try to count the beeps if you would like me to.
