It can be annoying when the system fails to boot and the system fan runs very fast and loud. This could happen due to various reasons. I suggest you to reset the BIOS to Defaults and check if the system works properly. Start tapping F2 key at the Dell logo to load the BIOS screen.
You will need to run the Diagnostics by booting from OptiPlex Resource CD if the system completes POST. You may also check the status of the Diagnostic LED's along with the Power LED and for any beep codes emitted.
Please let me know about your findings.
Thanks and Regards,

Thank you Rajath for your response. The problem is that I can't even get to the BIOS. The power button on the CPU and Monitor are illuminated amber, and nothing displays on the monitor screen. The fan is still screaming. What next?

Thank you for your reply and for providing an update on the status. An Amber Power LED indicates that the power supply is functioning, but the system is not processing data. I suggest you to reseat the memory modules and check if the system works properly.
Please let me know the status of the "Diagnostic LED's" on the back panel, if the issue persists.
Thanks and Regards,

Rajath, you are a life-saver! Re-setting the memory modules did the trick. Thank you so much.

Rajath, I'm afraid I spoke to soon. The condition has returned, and I cannot get it to boot up, even after repeated re-setting of the memory modules. I did notice, however, that my previous analysis of the fan that was racing out of control, was incorrect. It is not the Power Supply fan, but the CPU fan that is racing. Also, I did not see any "Diagnostic LED's" on the back panel. Where are they located? Please, advise.
