I think the capacitors look pretty good (I may post an image tomorrow morning). Is there any chance a video card would help?
Or perhaps a bit of dust in the ROM select jumper. Would taking the floppy drive apart, removing the dust, and then using a floppy disk cleaner disk work?
Could a broken/dusty floppy drive with a floppy in it stop boot?
P.S. The post above was my first!
