I'm trying to put an unused 2007 HP Proliant ML150 G3 server to use at the office. I was told it just needed a new PSU which i've installed but the thing won't boot up. After powering it up, the fans come on, it seems to run the BIOS fine, but after the summary i just get a black screen with a flashing cursor in the top-left corner.
There are no error messages, no beeps - nothing. I can't input on the keyboard, i can just ctrl-alt-del to restart it. I can enter the setup though and I've changed the boot sequence and tried booting from a Windows Server OS DVD but i get the same sequence everytime.
Has anyone got any theories please???
