You might not have your BIOS set to display through PCI-E. Try plugging your monitor in through the onboard VGA or DVI port and see if that produces any results. If you see the POST loading up, go into your BIOS and set your display through PCI-E.

If you're plugging into the onboard ports already, try plugging directly into your video card.

If both won't display anything, I'd try switching out the monitor.

No power to HDD, CD Drive, Cpu Fan but Mouse and Keyboard receiving Power


Hello i think your power supply is dead.

Try to replace it with one you know is working.

Here is the gigabyte homepage:

Try to download a manual after you find the right mainboard.

Good luck

Failed to boot, i cant even get to the bios! only the fan running, led(green) and (red) indicator doesn't even light.


Dear Client, unpluged all the data cables, power cables or wires, bios cell and RAMs. Everything should be unpluged from the motherboard for two hours and then reassmbled. It will work properly but when you reassembled it just plug with the follwing devices.

* Power Cables
* Data Cables
* Bios cell
* Processor + Fan
* RAMs

Do not attach CD-Rom or Hard Disk, just turn on the computer without Hard Disk and CD-Rom and try to enter in bios setup. I assure your problem will be solve. Now you can attach the CD-Rom and then try to boot up from the CD-Rom and in the last you should try to attach Hard-Disk. I hope you will do it step by step and get success.


Good Luck

No video


Go to the Asus website and download the drivers for this board. It's most likely that it did not come with drivers installed. Hopefully this will fix the problem. Good luck.

Monitor shut off, no BIOS post, no keyboard or mouse lights, will not boot


Try another (Known good monitor). Or try you're monitor on another system.
Remove all memory except 1 DIMM. Double check all data cables (internally) & power cables. Remove the added video card. Try booting the system. Watch for the case LEDs to flash/blink, listen for hard drive spin up /cd-rom spin up. Lastly pull the battery & check with a volt meter. Bios battery should test no less than 3 volts. Post the correct MD rev.

No post beep, no video


had a similar problem with a box i built. Your power supply has two connectors. One long one and a 4 pin connector. Make sure that four pin connector is connected.

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.

Not posting


Maybe a silly question to ask; but did you connect the processor power lead, as unlike some processors this needs a seperate supply.
