1st. check your memory sticks, if you have two, flip\flop them around. if you can replace (don't buy them if you can until you are sure that they are damaged) or substitute them for a "lower" value & frequency range. Just to see if the computer turns on.
p.s. are putting the computer together for the 1st time?, Was the computer working before the problem? if so you could have said so!

If the RAM is incompatible with your board then yes it would not allow a boot. Make sure your front panel power wire is plugged into the proper spot on the motherboard and retry. If it's the RAM then you will still have the problem. If it was the wire loose or in wrong spot then it should work. Hope this helps & please remember to rate my answer. Thanks.

At first I thought your screen went black during the start up process. After seeing the bios screen. In which case I would've said it was a bios setting for the display. Then I realized that I think you mean that their is no display at all. When you push the power button. Only the monitor led light. So, it may be a problem with your RAM stick/s. You should make sure that they are properly seated in the mother board. If they are new, make sure they are compatible with that motherboard. If you can you should swap them out with known good ram sticks. You could also try installing a video card and see if you can get display to work through that one. Make sure your main power supply wire connector is pushed in all the way. Swap the power supply with a known good one if you can. If still can't get it to work you may want to take the motherboard out and inspect it for burns, cracks, and anything that doesn't look right. Maybe contact the manufacturer of the motherboard and ask them what you can check. hope this helps.

SOURCE: Just installed a new Gigabyte

motherboard to hard drive leads

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they could be faulty ?
one bad lead will end with a computer error a computer needs its connections continue its cycle and have an end to function properly

even something as small as an electrical extension or a faulty fan lead can cause this problem computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly

a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

hope this helps
