Can you see any of the P.O.S.T. at all?

Can you explain P.O.S.T. please? There is nothing on the screen. The monitor doesnt get any signal at all from the computer.

post=power on self test
the screen you see before windows loads...memory count, hardrive detection

In trying to troubleshoot a problem like this we have to narrow it down to a hardware or software problem. Right off the bat I sence a hardware problem, but Im wrong many times too.
Lets assume we are talking about a hardware problem first. One of the ways to see if its hardware related is to watch the post (power on self test) during boot and see if you can determine if it completes. Power on self test is a process by which the computer "looks" at some of the hardware on the computer and I think even assigns simple firmware type drivers to simple devices like the floppy drive. This process usually takes about a few minutes at the most and is visible under certain circumstances. Sometimes though this process is not visible for various reasons.
To you, it would look like a bunch of writing on a DOS type screen. The info shown is displayed quickly and has info related to your hard drive, and all the other drives and other hgardware on your computer.
Now, let me ask you, when the computer was working correctly, have you ever seen this info flash on the screen while it boots? Or have you seen it on another computer?
If you have, you now know what to look for if it is visible. And if we can see it, we may be able to determine if the post is completeing properly and that would mena a good bet your hardware is ok.

Is the fan working on the power suply and on the cooling fan for the cpu?

Thats just the problem. Nothing appears on the screen like it used to. Not a character at all.
Before when it worked the computer emitted a bleep when starting boot followed by the check-sound of floppy and cd-rom together with the text on the screen you mentioned. However, now no text appears and it seems it only checks the cd-rom and not the floppy... I dont remember the boot order but i think its 1)cd-rom 2)floppy 3)HD.
Hope that clears things a bit.

Ok, seems at this point like somthing during post is messing up ( a hardware problem).
Again, Is the fan working on the power suply and on the cooling fan for the cpu?

Ok , this may get tough now. Next question.....are you sure you cant get into bios? Have you gotten into your bios b4 on this computer?

Ok, what id do next is check your power supply voltages. This can be done 2 ways, either manually with a multimeter (youd have to open the case and know what you are doing)
Or...from the bios (which lists the power supply voltages, thats why i asked about if you could get into the bios.
Do you think you want to attemp this?
One fast thing you might try....reset your bios. Let me know if you dont know how to do that. However, with the fan not working on the PS, i wonder about its condition at this point, do you have a spare PS?

I dont know how to reset the bios, and I dont have a spare PS. I have a multimeter and I could try to check the power suply voltage, although Im not exactly sure how its done
