Just powered up a brand new PC with Windows 7 pre-installed and I havent got a signal to the monitor (faulty video card I think). My dilema is, is it safe to power down the PC at this stage. Presumably, Windows 7 is asking me to set it up etc. Or is it safe to power down now, without affecting the set up at a later date. Support from the PC manufacturer is out of hours for the rest of the night so I cant ask them.
