My "new" computer started singing to me yesterday when starting up. It sings a continuous beeping of many short beeps that almost sound like one long continuous beep interrupted by clicking. It stops as soon as Windows starts up. Then, almost always on the first start up, I get crazy stuff happening, such as clicking on a shortcut icon and while the program is starting Windows wants me to confirm I want to delete the shortcut. Or being unable to find any plug and play camera such as my iPad. Sometimes it takes one or two reboots to get things working fairly normally again, but that Carol of the Beeps is every time I start up.
This is a Dell Optiplex GX620 running Windows XP.
As much as I love to hear pretty music, this little refrain sounds scary to me.
