Put this altogether, installed windows 7 pro. Worked great.Did some windows updates and shut down for the night.Turned on the next morning, powers on, but screen stays blank.Unpluged all drives and all but one stick of ram, restarted same thing.Tried reseating all cables and drives...nothing.Unplugged power supply removed cmos battery and cleared cmos with jumpers.Same thing!No beeping sound like a failure.Can't access bios setup to restore defaults(which I think would by resetting cmos?)Tried videocard in another tower works fine.Even tried different videocard.Removed screws form motherboard to make sure the board isn't grounding out on chasis. Any ideas at all would be great...still under 30 day warranty, don't want to have to send everything back just to find out.One thing i did notice the last time I tried to get to work, the fan on the videocards rev up and down like they're cycling.The video card does not have a power adapter all through the PCI slot.
Thank you in advance for any help!!

  1. Pull it all apart and start from scratch, systematically putting in CPU/RAM, boot (it should turn on but no video obviously). Install GPU, boot then next item (HDD or optical), boot. Keep systematically installing one thing and booting and try to isolate the problem.

    If it doesn't fire with just the CPU/RAM there may be a problem with mobo or CPU. Have another CPU that is compatible with the board to try and rule it out?
  2. tried to reinstall every thing like u said..i don't have another cpu to try.comes on just can't see anything or access the bios(can't see)
    thank you
  3. What exact GPU do you have?
  4. XFX Radeon 6670 1gb pci-e
  5. Have you tried one of the other PCI-E slots? That board has 3 right?
  6. yes...still no go
  7. Gigabyte has just contacted need a non FX chip installed..then update bios..then put FX chip back in

    Answer : Dear Customer,

    is there an non FX processor available to test with?
    The bios will need to be updated first to support the FX processor.

    Question : When I start computer the screen stays "Black"- no signal, but pc seems to be running. (activity on HD light).I replaced video card in another pc and works.Reset Cmos,removed and reseated all cards one at a time.Removed all drives.Still the same thing.Left it run overnight, nothing on moniter.Tested moniter works fine.I even put another video card in and still no go.It did run the very first time, windows made some updates, wanted to restart.Nothing after that.I should, I would think, be able to access Bios at the very least.Thank you for your time! Christian
