Boot Issues

[Siron]

I have a 2008 MacPro and I normally leave it turned on and let it sleep when I'm not using it. However I had to shut it down a few days ago and after hitting the start button nothing happened -- just a gray screen. I restarted with the PRAM keys and it booted okay. Now I have to do this every time I boot it up.
Any idea what's going on -- could the MB battery be going bad?
Thanks
Alan

I've been having a similar problem for the last 6 months and haven't yet figured it out. But mine is probably a different issue. Mine is 2010 Quad 5,1 originally 2.8.

Anyone have any ideas?

Well it is good that it is responding to key commands at least. Try booting up in verbose mode (hold command-V) to see where/what step it is hanging up on.
