I have a HP Proliant ML350 G3 server that I just upgraded to windows server 2008 from windows server 2003. It has been fine and we have had it unplugged for a bit until we made space to relocate the server physically. I added some memory to it (it now recognizes 8 gig), but it keeps rebooting itself and/or shutting down. I have an identical server I use for parts and tried swapping out the power supplies, same thing. I cannot get it to stay on long enough to check the Event Viewer and thought I would post the question here to see if anyone has any thoughts or ideas on what to try.
