My MacPro makes several attempts at starting up before succeeding. Is this my Logic Board going bad?

I"m no Mac expert, so the best I can give you is maybe. Try running Apple Hardware Test if you can. On Reboot, hold down Command R (I think) which should get you to the all-in-one helper (sorry, forgot name). there you should be able to choose which hard drive to start up from and then do a repair on it. It's not normal, that's for sure..
It could be the logic board,video card or hard drive. the Radeon X1900 is known for clogging up with dust and giving up the ghost a bit early. try shutting down your Mac Pro, letting it cool, take off the side panel, grab a can of compressed air and go to town on that video card. You may find a whole bunch of dust bunnies in there. that being said, after doing that, putting the side panel back and rebooting, the SMC may need to be reset. If that doesn't work, it could be the logic board, so you'd have to take it to your local authorized Apple repair place. Oh, I"m not totally sure if this is still good, but there might still be a recall on the X1900 video card. Check to see if your video card is one of those affected ones. Just a thought. If you can, a new ATI 5770 video card is around $250 in price, not too hard to install and will be better than the X1900, if you can afford it.....

You know all the issues there are with that ATI X1900 and dust and heat right?
Also about heat and cooling FBDIMMs where extra care and increased fan speed is a must?
I would of course continue with Safe Boot, Recovery Mode, and to also clone your system for bootable backup with Carbon Copy Cloner.,
Might want to get the ATI 5770.
More RAM definitely.
Proper cleaning of dust bunnies.
