I have installed a Pentium 1 motherboard for 120MHz processor. When i turn the pc on my sceen doesn't light up. I don't know what version of PI mb it is and I don't have a manual. Can anyone help me, it's very urgent, because that pc has to be used as a server! Plzzz help me.

Hi there first things first...

Questions:
Did the monitor work before the change of motherboard?
Can you test the monitor on another machine that works ok?
Does the system POST with a nice system beep to confirm things are ok?
Is there power going into the monitor?
Check the leads and then check the leads again!
Once you are sure that the monitor is working you can address the motherboard.
If it is not the monitor then its the board. In which case going to need some details with respect to what you are doing/ have done ie upgrading, fixing etc. lets us know some details and I'll see what can be done.
Most of all don't panic it doesn't help: clear thought and execution is what we are after. Good luck.

Hi JPM,

The monitor works, because I use it on my other pc.

I do not hear a nice system beep. But all of the leds on my keyboard (num lock, caps lock and scroll lock) are lighted up.

Yes there's power going into the monitor, cause the led on my monitor flashes, but normally after 3 flashes the monitor turns itself on, but that it does not do.

The problem, is i don't have any information on the board. Because it's from a friend but it should be ok. Now how can i see on the board wich version of intel pentium 1 board it is?

I hope you can help me further.

Allready thnx for your reply.

Bye

Youve tested the monitor on other machines and thats ok.

Your graphics card could be U/S which as long as its not onboard you can change.

However a very common cause for this and would cause you not to get the correct POST Beep is RAM.

E.g
Faulty, Wrongly inserted, in wrong slots, not in correctly, wrong way round (forced in) if 72 pin may not be in correct pair, wrong type of RAM i.e 66mhz on a 100mhz board.

How big is your network, seems a very slow server.

Hey,

I allready tried other video cards, and they don't change a thing.

I don't think its the ram. I tried the other slot, so what can be the problem?

I realy need help http://www.PCGuide.com/ubb/frown.gif

thnx and bye

Hope you've fixed it by now but if not heres a little help:

We now know the monitor is fine which is a big step forward. This means the motherboard and things attached to it have a problem. (Excuse the patronising note: I'm think aloud).
Lets make sure that its not the graphics card. Take the graphics card out, watching out for electrostatic discharges (ESDs) and test in another computer. If this is ok ie it works in another computer then its not the graphics card.
The pattern for finding out whats wrong is try and find out whats right.
With the monitor and graphics card working ok then its the MOBO.
This will be fun. You mentioned 'installed a PI MOBO for 120mhz.....screen doesn't light up'.
Look at the processor again: is it down set ok ie all the pins in and the little handle pulled down? This will be a socket 7 and the CPU hole (not sure on the techical words) and there will be one corner with no pins making it easy to align.
Now, if the processor is sat down correctly and you still get the same problem you may have bust the CPU (NB those dreeded ESD which nobody suffers from). Again to test this try another CPU. If you don't have one let us know and I'll send you a spare p75.
Don't worry about the motherboard manual this will only tell you a few details and its not essential. As I said before eliminate the obvious and work your way in.
Bear in the mind the following: you don't know what the problem is so suspect everything.
RAM: if the RAM is not very well you get a lot of bleeps. If the RAM is bad and the system speaker is knackered oh thats another story....

Hey

I don't think its the videocard, because i tried other ones and they give the same problem.

No what??? I don't know it pfffffff

bye

At this point in time you have three choices. RAM-- CPU--- Mboard. Providing everything has been assembled correctly. And your friend passed on to you some good hardware. Begin with the memory stick. Swap it out for another if you possibly can, if not, check the pins closely. Re-install it a few times. Making sure it's seated properly. Check it out in another PC. Bad RAM (or improper installation thereof) causes a Ton of Grief. You aren't getting any beep codes? System doesn't go thru a POST? Some older Mboards require Ram to be installed in PAIRS. We have to check the CPU and it's arrangement closely. Did you install it correctly in the ZIF socket? Remove it. Check the pins closely. Can you try it in another PC? Did your dog use it for a chew toy? And on to the Mboard..... Are you positive you have the jumper's etc. configured properly? If not the CPU isn't going to start hummin'. Next remove the CMOS battery. Go shoot a game of pool and come back and re-install it. Turn on your PC and and stand back. It may function! .....Think Memory .....CPU .....Mboard.
Look on that Mboard for a long ID code. I need letter #6 and #7 of that ID "string." I'll try to get you a Mboard ID.

Nice reply Mr Ranchdog,

With respect to checking the RAM, take all the sticks out and turn on. This at least tell you what bleeps you should get with bad RAM. Try this with the CPU out again to see what happens. Hopefully you'll learn something. Now we know that its not the monitor or the graphics card and we should know if the CPU is ok and the RAM is fine. This is assuming the board is not toast but if the keyboard is lighting up this might be ok. Is this where I suggesting binning it and buying a new one?...Never computers are too yound to die. Can I ask E4stsid4H what your trying to achieve. I don't know much about servers but I thought that they were power computers with lots of processors.

Where all here to learn!

http://www.PCGuide.com/ubb/wink.gif Get me the FCC ID code # off the Mboard and I'll give it a shot with finding the spec's for it. Have this strange feeling you didn't set any jumper's etc. on this unit before you tried to use it. One "size" does not fit all. With that said.....Hang In There.
