But you know the key to get into the BIOS.

Just power off the system and when you power it on press the BIOS button.

Ah sorry you didn't say so I didn't know.

Have you tried the monitor with different cables?

Also please explain in detail what happens when you power it on!

First of all is there a speaker connect to the motherboard, if so remove all your ram and see if you get error beep codes. If not it's more than likely the motherboard. Also when you said you connected the monitor to the motherboard did you also remove the video card, if not the bios will still try to boot to it. Also have you tried resetting the bios.

Perhaps you have no BIOS because you need a new BIOS battery.
Removing the battery to replace it will reset the BIOS as well (don't put in the new one for half an hour after the old one is removed).

If the battery was dead then the bios would still be there and boot it just would not save the setting when the computer reboots.

I tried removing everything (ram/HDD/graphic cards) but still I get no beeps. I just start the computer, the fans start spinning, but nothing is shown on the screen.

It sounds to me like either your motherboard or your processor is toast. I would suspect the motherboard.

If the processor was toast, wouldn't the PC shut down after a few minutes?
