Hey Roughwoodsstudio;
Let me see if I can offer some advice even though I do not have version 5 or 5.1. I will assume it is not a software issue, although you could try reloading your software (5.0 or 5.1), Service Pack 3, and see if if that helps. MIND YOU, make sure you have the Unlock Codes for 5.0/5.1 and all you plug ins that you use. If you don't they will not come back to life, Just a reminder in case you forgot or didn't know.
I have had the "Flashing ?'s" before and never "really" found out what it was. I cleaned all the edge connectors and ribbon connectors inside the d8b. Clean all power connections and the back-plane connector, changed the Battery and checked the BIOS all to have the same results. What I did do that worked but made no sense was to change PSU. Same software, version 3.0. Changed it back to the "I'm not going to work for you "PSU and it worked? WTF!
Type "Flashing ?" in the search field at the top of this forum. You will find some info there. Crash has some insight into this.
The other thing I can offer is to clean all the ribbon cables and connectors (I think you said that but use a good quality cleaner), and make sure they are firmly reseated.
I will try to do some searching for more info and get back to you.
Post back with other Q's and what you have learned.
Thanks
Bruce
PS. What a great website you have!
