This is from the geekstogo forum...which is also a good tech forum...here it is. By Doby BIOS beep codes 1- Make sure you have a case speaker connected, if you are getting 1 long continuous beep this indicates the system can’t find usable ram, reseat the ram, try different ram or try the ram in a different dimm slot 2- 1 long 2 short indicates video error reseat the video card, try another video card Nothing on the screen with no beeps 1-Make sure the hs (heatsink) is installed properly, tight with thermal paste applied 2-Make sure the cpu fan is connected to the correct header on the motherboard 3-Clear the cmos by unplugging the computer removing the battery then move the clear cmos jumper from pins 1&2 to 2&3 for 10 minutes 4-Replace the battery and move the jumper back to pins 1&2 5-Verify all motherboard jumpers are set correctly 6-Verify all case connections are correct ( case switch ect.) 7-Verify the power supplies 20/24 pin and 4pin 12v are tightly seated to the motherboard Still won’t go 1-Remove all drives and cards except the video, remove front sound and usb 2-Repeat the above 3-The idea here is to get the computer to post and boot into bios if after doing so you are able to get into bios let the computer idle in bios for a while and watch the temps and voltages. 4-If everything appears normal load the bios defaults and make sure to save and exit 5-Now add the drives and install windows then add the remaining cards Still won’t go 1-Remove the motherboard from the case and place on a piece of cardboard 2-Install only the cpu with hsf, 1 stick ram in dimm 1, psu, video card, case switch and case speaker 3-Connect ps2 mouse and keyboard along with the monitor 4-Repeat the above and power on 5-If the computer now boots into bios you most likely had a case short so make sure when installing the motherboard in the case that you use standoffs and they line up with the mounting holes in the motherboard and none of the standoffs touch anything else on the underside of the board.

Check and make sure your processor is properly plugged into it's socket. If it isnt plugged in right, you'll have everything lighting up and spinning, but you'll get no video.

i am having this same problem, although i am not putting my system together, its been together for 2 years now. i installed sp2 for xp today, and restarted, but it sat at the blue screen right before restarting, said windows is shutting down, it took 10 minutes, so i powered down, thought it had froze, when i powered back up, it doesnt come on, power comes on, no beeps, no anything, monitor is green light flashing. i read this post, and i tried all the things you suggested, besides taking the motherboard out, as i know i installed it correctly, and that would be a pain in the butt. so i removed the cmos, waited 15 min and put back in, put pins back etc, i tried minimal boot, no hd's or cd-rom, just 1 memory stick, and video card, still nothign, i get NO beeps or anything, i think the internal speaker is hooked up, but i will check that next, to be 100% positive. I tried ram in diferens slots, tried another video card, reseated the video 2 times, still nothing. CPU is fne, is seated corectly, its not overheated, it has a nice hs fan on it, and its worked 2 years now. I think when i powered down it shorted somethhing maybe i tried taking out ALL the ram, and i STILL dont get a beep, something wrong there...but i will make sure internal speaker is on...might be so simple...
