Err... sorry for bugging you, but I cannot identify anything that might be the fuse on the MB... and, what should I do when I finally find it?

Don't worry, you most likely won't find one.

I'd be looking at the backup battery on the motherboard first. If it's an old ni-cad then there's a good chance it's leaked and stuffed the board.

Also try to just unplug everything and then plug it all back in. Give the bios chip a bit of a push down if it's socketed, and remember with an AT power supply cord/s to the board, blacks go in the center. Oh yea, and try the video cards in different sockets.

But in the extreme case, (most likely), just scour ebay for another motherboard. Should be able to get a 99c one.[/b][/quote]

Sorry MV75, old mobos did had fuse. And were 2 to be exact. One was the power supply fuse. In some models this fuse was outside the power supply, and within in others.
There’s nothing on the board that you can fix, but it’s worth looking at the board in order to check for obvious signs of damage such as a blown fuse or some gunge leaking from the large cylindrical capacitors. Never replace a blown fuse on a power supply. If the fuse blows, it has probably blown for a good reason (such as one of the PSU components burning out). Replacing the fuse is dangerous, and can also damage components on the PC’s motherboard. Removing the case from a power supply normally involves just removing four small screws to expose the circuit board.
The other fuse is the keyboard fuse, which often blows if a keyboard is plugged in or removed when the PC is running. The keyboard fuse is usually a subminiature surface mounted component that is not immediately recognisable as such. Look for some thing labelled F1 or F2 and located near the keyboard connector (on the motherboard, not in the PC). :whistle:
My first advice would be to check power supply components. If you ´re brave, open it and check. Of course, be sure to remove the case with the cord unpluged at least 5 hours before. Taking the case off a power supply exposes you to voltages that can kill due to high capacitance of them and high voltage can exist even if it has been turned off for many hours.
