I have a D610 Dell Laptop and it does not boot.  It does get power becuase when I press power I get the Numeric Lock and the power light and two beeps.  I found somewhere to boot and hold Fn and this gives me some type of cycle, runs through all lights, and then stops on Caps Lock.  I was only able to get the machine to post once and I got a TPM error and an error about a change in RAM size.  Nothing on this laptop has changed from the time of purchase and is in otherwise perfect condition.  Has anyone else seen or heard of these issues and how I may fix this?  Thanks!

BTW, the machine is running the latest bios, 6.
