I face a problem with my old motherboard Intel D875PBZLK, which also has an Intel Pentium 4 (478PIN 3,0C Ghz) on.
One day recently and since then the computer does not boot. It does not even POST and I get to signal on the screen. There are 2 beeps that sound as 1, followed by 8 beeps. This is confusing once I can find what the 8 beeps mean but not that other first one. So it's like 1 beep 500 miliseconds delay and then 8 beeps.
In any case, what I have done so far is the following:
I took all hardware off the case completely.
I setup motherboard and PSU (600W) on the table.
I took off the CPU, cleaned it, put new thermal paste properly and put it back on.
I made sure all power is set correctly for both CPU and motherboard and that CPU fan is connected.
I have tried different Ram DIMMs in different slots. Right now it only has 1x512MB on.
I have tried with and without the VGA on.
I cleaned the VGA and also applied new thermal paste on it as well.
I took off the battery for more than 15 minutes to reset the bios and put it back.
I reconnected the floppy drive without any diskette in (I do not have the bios diskette).
I tried using a USB stick to boot including the P34-0125.BIO file inside and no jumper on J9J4 (nothing happened).
I tried setting the jumper to position 2-3.
No fans connected, no other cards, all 5 pci slots are empty, all SATA/PATA cables taken off, nothing connected except what I describe above. In all the above cases I get the same number of beeps except if I completely take the J9J4 jumper off which I get no beeps, and if I set it back to 1-2 and take all Ram off, which I get 3 beeps (as it should – good sign maybe). So when the VGA is not on the board I still get those 8 beeps (plus the mysterious first one).
Now, the floppy drive attempts to load every so many seconds if I set the J9J4 jumper off, but unfortunately, I do not have an external USB drive to use on this or the other computer and store the .bio file right now. I got no way to install this floppy drive to all those other new computers although I searched all the Internet and there is no hack I can attempt.
I do not suspect the PSU, maybe because it was the most new I bought and looks like it is working good. I think the VGA died. The thing is, where to find an AGP vga nowadays ?
I am a fan of Intel and all my motherboards and CPUs are always Intel and this motherboard from this old PC is at an excellent condition and I love it. Although I am ordering a new PC next week, I feel it's a shame for this old PC not to be my ubuntu server giving me DNS, Web, FTP and more services on LAN – This is my job by the way. I would just hate to see it dead.
What do you suggest ?
Are there any things I can test ?
Thank you !
