I have intel 845glly motherboard. it is not beeping and not displaying
anything but when i remove the Ram, it start beeping . i checked my Ram on
another computer. it is ok
can anybody help me ?

well that means that the computer is atleast responding to the fact that ram isnt present, which is a good sign twards your motherboard still being alive. try one stick of ram, no hard drive, the video, no CD-ROM's or anyother thing connected by PATA or SATA and see what it does, what you also may try is Sylvanders charts

download them and see what progress it is makeing

Hearing those RAM test failure warning beeps tells you that that the POST is running and getting at least as far as the RAM tests.
That means that some test after the RAM test is failing and halting POST so that it doesn't get so far as to initialise the video card, then begin displaying on the monitor, complete the POST, and give a single short beep before attempting to load an OS from a drive.

Is this setup older or new? If older, was it previously working fine?
Did it previously give a single short beep at completion of the POST?

Most likely cause is a failure of the video card to initialise.
Try reaseating the card.
If that doesn't produce a fix, try cleaning the card contacts, then the socket contacts with Isopropyl Alcohol.
Try borrowing and fitting a known good card.

Ideally you'd be doing this with the system "bare-bones".
i.e Mobo out of the case on a non-conducting surface.
Only connecting PSU, mobo, CPU+fan, RAM, video card, on-switch.

Here's that section of a generic Phoenix BIOS POST...

Notice in the list above that other causes [not so likely] could be faulty system and/or video BIOS shadowing to RAM [faulty RAM, but not showing up in RAM tests by the POST].
Can you run "Memtest86" on the RAM in another PC?
