Hi,
The colours could well be telling you what is wrong:

My advice would be to re-seat all socketed chips and disconnect any hard drives, accelerator boards, zorro cards and see if you can get the purple 'insert' disk screen. If you're not getting that far then it's worth sending the board to an expert to look at.
Good luck.
Steve.
