I have a Dell Studio 540 wiith core 2 quad and 6 GB RAM. I get three very brief POST beeps every boot. I'm a tech so I've been thru the whole troubleshooting routine. Beeps have occurred with different drives, video cards, mice and keyboards. They occur with no peripherals plugged in. Power-on memoery test was good. The motherboard service manual doesn't have the POST beep codes. Beeps occurred before and after a BIOS update. I'm not having any problems so I hesitate to re-seat / replace the BIOS chip. Any suggestions? Where can I find listing of POST beep codes for this PC?
