Unfortunately the MB does not detect a no RAM condition and that generally means the MB is having problems. Thanks for clearing that up and sorry I could not give you more encouraging advice.
In need of some help, I've had a optiplex 7010 for a couple of months bought of ebay and have been using for work. I turned it on today and a amber light came up for about 1 second and powered off instantly. Light is showing that there is a system board failure. Not sure what to do so any advice would be great.
