I bought a new Dell XPS 8700 last fall. Lately, the damn thing seems to work like an alarm clock ALMOST every night around three or four am. I wake up to hear three rapid beeps over and over. This lasts for about a minute. This happens even when I shut it down.
Googling has told me that this can be a sign of motherboard failure.
The beep is that same loud chirp you hear when you start up any PC. I managed to make a short video
one night. I know the video shows the thing positioned right next to a toy box, but trust me, it's the CPU.
I called the help line. They took over my computer and looked at records of bad shutdowns, errors, etc. They told me other than a few bad power downs (Due to power outages), everything was fine. They said I should turn off my computer each night to stop the beeping.
Even powering down the damn thing does not stop it. At least once it was shut down (not in sleep mode) and it still woke me.
Besides, I've always been told you should just keep a CPU running. I rarely turned my last one off in 7 years.
It always used to go off right around 3 a.m. Since the spring daylight savings time switch, it now goes off around 4 a.m. But not every night. Most nights. Help?
