Refurbished Dell Optiplex 760

I just bought a Refurb. Dell Optiplex 760 with Vista Business to replace an old dead desktop. I plugged it in, but it makes a series of beeps, lights up the power button, the fan is running, but it doesn't light up the monitor or recognize the keyboard, or of course, the usb mouse. I've contacted the ebay seller, (99.7% rating) but am wondering if there are any simple suggestions in meantime.Thank you!

 

The series of beeps can be used to determine what the problem is. How many beeps does it do before pausing and is the next set of beeps the same?

 

Read here and check the lights on the computer labelled 1, 2 3, and 4.

scroll down to the section Diagnostic Light Codes During POST and tell us what those are showing.

 

Ah, thank you! I didn't realize there was a Morse Code involved with the beeps. 1 long, 3 short, 2 short. The 3 and 4 are solid green, so it looks as if it's a memory problem. I'll call the company tomorrow, and see what they'll do.
Thanks again, Major Geekers!

 

Depending how comfortable you are with working with hardware you may want to unplug the computer and open the case and try reseating the memory modules. Perhaps something got loosened during shipping.
