Pretty much as it says above in the title.
System boots to the point where it detects the drives etc. then flicks to the screen as described - this is normal of course, although usually only for a matter of seconds; whereas at the moment, it's sitting there for minutes on end at this stage, and getting nowhere.
As i'm a hardware novice (i'm guessing hardware issue here!), I thought i'd ask for suggestions as to either what the problem might be, or indeed, how it could be fixed, before attempting to crack it open and "fix" it.
Any suggestions, advice, comments would be much appreciated..
