Whats gone wrong?!

[Jonny]

My old PC is having problems. After tidying up the cabling inside, it no longer starts up.
The bios detects the hard drives and optical drives, but not the floppy.
I press F1 to continue and it hangs on a black screen with a flashing _
I have checked the connections, and reset the bios.
Any ideas anyone?
Thanks

dissconnect everything, all CD/DVD drives and floppy power and just leave the HDD. If it boot's ok start plugging everything back in and booting one by one to see if you can isolate the device that's playing up. You may have knocked a card lose while you were in there, so try reseating you GFX card or etc too.

It was my gfx card before, but have checked that.
I'd normally do all that,but spent ages tidying all the cables and was wondering if anyone could recognise the fault before I took everything apart. But thanks for the advice, I'll try that if nobody comes up with anything tonight.

Is your floppy drive's LED stay on all the time? If yes flip your cable around (since you attached it the wrong way).

Yes it does! Lol
Well I gotta start learning somewhere! Cheers mate.

That's a classic - Anyone who has built a PC will have scratched their cranium wondering wtf have I done wrong, pulled the damn thing apart only to realise that said floppy cable was in upside down. . Happens to the best of us.

This is one of the reasons why, in the aircraft industry, we implicitly design bits and pieces to only fit together one way. Stops those Murphy (Law) moments.
