My laptop beeped three times when I turned it on, but otherwise booted up as normal. When I restarted it there was no beep until I opened my browser and got one beep. That night I shut down my computer. This morning when I turned my computer on it beeped twice, but otherwise is working normally and there was no beep when I opened the browser. I restarted my computer and got no beeps. (It is not really a beep anyway, more of like "Neeeh" not as high pitched as I think of a "beep"). Should I be concerned? My computer runs fine.
