My computer makes a LOUD beeping sound when I start it up. It sounds like a siren. I've heard that the number of beeps tells you something about the computer, but there's no beep rhythm or anything, it just beeps continuously. It beeps constantly for about 1 minute-1 minute 30 seconds, then it starts up normally. It only makes this beeping sound when it starts up. It happens every single time I start it up. Here are the specs of the computer: OS: Windows XP, CPU: Intel Atom N270 1.6 Ghz, CHIPSET: Intel 945GSE family, RAM: 1GB 533Mhz. Also, I've had the computer for probably 4-5 years now. Also, I completely reset the computer to factory settings about a week ago. Also, this is an Acer Apire one Kav60 NETBOOK. This is NOT a desktop.
