    Unhappy GA-Z77-DS3H Can't access BIOS, no OS, but Spalsh screen is there [Solved]

    [EDIT: SOLVED! Please see next page for details.]

    <figure class="usrProfile"><figcaption class="line infosHold"> </figcaption> </figure>
    I am copying my post from the Tom's Hardware forums, in hopes of getting more answers. Original thread here.


    Last night, I put together my new system, and everything went well. I didn't try to access the BIOS, but when I put in a flash drive with the Unibeast Installer, it went to the Language Selection page without any problems. At that point, I needed to leave to work, so I decided to power down the computer, in case anything happened while I was gone.

    When I got home, I restarted the computer, and I couldn't get the installer to get to the Language screen again. I tried re-laoding the installer onto the flash drive, but it wouldn't work. So I tried resetting the BIOS (probably not the smartest thing I did yesterday).

    Now, I can't access the flash drive, and I can't access the BIOS to change the settings. When I boot the computer, I get the splash screen for 1/4 - 1/2 seconds, but I can't get anything beyond that except a single "-" that flashes once, then goes away.

    If I hit the reset button instead of powering off and on, I only get the "-". I get the same result if I mash the "Delete" key from power up. I have tried this on a USB and a PS/2 keyboard. I have tried unplugging the USB mouse, and disconnecting my SSD from SATA.

    I have tried pressing F9, F12, END, DELETE, ALT+F2, and F1. I can't get it to work.

    It is possible that there is a POST screen that would give me more information, but since I'm using a CRT, it takes a bit to warm up enough to show anything.

    The splash screen seems to be at 1024x768, but my monitor looks like it's only getting 800x600 or so of it.

    If I hold down CTRL or ALT during power-up, it will freeze at the Splash Screen until I release the button, or press another button. This works with either PS/2 or USB keyboards. I just tried resetting the BIOS again using the technique listed here http://www.techsupportforum.com/forums/f15/solved-bios-... . The results were exactly the same as before.

    Just leave cpu & ram , unplug drives etc. and make sure your keyboard is at one of the USB2 ports and keep hitting the [DEL] button after you power on, also you might press the clear cmos button or remove battery for few minutes.

    I'm down to a VGA monitor, a PS/2 keyboard, the motherboard, the processor, the CPU fan, 1 stick of RAM, and 1 system fan. I'm not sure I can unplug anything else. I'm still getting the same symptoms. I've been resetting the CMOS with no luck, either by pulling the battery or by connecting the "reset CMOS" pins.

    Pull the power plug, then pull off cmos battery. Then put jumper to cmos clear pins, or short them with screwdriver or some other conductor. remove jumper/short , insert battery , replug the powercord , press start and immediatly keep janking the del button (dont just keep it pressed ).

    I have reset the CMOS by removing the battery; removing the battery and touching the pins; keeping the battery in and touching the pins; removing the battery 20 minutes, touching the pins, and pressing the power button repeatedly; removing the battery overnight, and touching the pins; and probably a few other methods I've forgotten.

    Ok, then power off and remove all ram, then power back on, maybe it resets the mem settings and returns to default settings. Then power down and insert ram back and try booting and getting back to BiOS. If you can't get it back to safe settings, maybe it's time to replace the board rma or seller. Also you could try with another ram stick / keyboard if available.

    I just tried your suggestion. I ended up with exactly the same results as before.

    Have you tried usb keyboard or usb adapter with current ps/2 one? Maybe your ps2 port is gone fubarred. Mostly seems like something is corrupted in BiOS , id get it replaced.

    I've tried it with 2 different USB keyboards. No difference between the two or between them and the PS/2.

    If it doesn't respond to keyboard and can't reset BiOs, only option is to make a bootable media ( cd or usb) that does bios flashing , and try auto flash to latest bios, shouldn't be that much of hassle if it was working properly, just replace the board.
