The things to check when your system will not post are RAM (make sure it is in all the way) Hard Drive (make sure it is properly connected) Your CD/DVD drives (again check connection) and your video connection (if you have onboard graphics, this may not apply, if you have a seperate video card make sure it's properly secured in the PCI slot)
Once you've checked all of these things, if you still have a problem, listen for the beeps that come from your computer's motherboard and remember the order of short and long beeps. Respond with the beep sequence and type of computer you are using.
If there are no beeps, your computer is failing the POST. I'm assuming the system is actually powering up--you didn't say it doesn't. I would disconnect all peripherals (HD, CD, any cards) and try to start with just the CPU, memory, and video. You could also swap memory sticks if you have more than one.
If it still doesn't start, I'd guess the motherboard is toast.
If you can still go into the BIOS screen, disable the change you made and see if the system returns to normal. If not, and you do not remember the settings, go for the default...
Ground yourself to the chassis to dissipate static electricity, with the system off, remove the bios battery. This will undo any changes you made. It will also undo and system changes that make you system unique. At least it should start working again. You can go from there.
i got the exact same problem then checked all the connections and the few jumpers i had,replaced battery, tried to get video , no onboard video, put in video card, got video once, still no beeps, retried to set up hd and install windows...then everything went at once, no beeps...never again...this was installed in a net pc with 1.5 gb memmory, board, no beeps, tried reinstalling chip and fan, power supply, checked all jumpers and wiring,,,all i can do i s replace motherboard i guess, must have shorted somewhere or kilt bios / cmos...
You could try a program like EZ-Flash to flash the bios without using a dos disk. Gigabyte should have some type of program on their website that would do the flashing without makeing a disk as most new computers do not have a floppy drive nor does Windows XP/Vista use dos. Hope this helps.
First, remove all power from motherboard, including the Power Supply ATX plug. Then remove ram and all PCI and PCI-E / AGP (Video) cards even network cards... Let it sit for about 5 minutes and then plug in the necessities: RAM, Video Cards and if nothing works repeat the process but alternating ram slots and ram.
The best thing to do in this situation is to build your machine outside of the case, using the minimum amount of hardware,
Remove the motherboard and using only one stick of ram, the monitor, keyboard and mouse. short the power switch connector on the motherboard with a screw driver for a fraction of a second just to power it on.
If it starts up and gives you a "no boot disk" or "no Operating System found" at least you will know it's working and you can slowly connect everything else one by one to see whats preventing it from booting.
If it doesn't start like that, remove the power cord from the power supply and remove the mother board battery for at least 15 minutes, this will clear the BIOS and set it back to factory spec, now carryout the out of case procedure already stated.
