I tried updating my DH77EB motherboard's bios (recklessly to the latest version without going through a progression)
using the Windows method. My computer restarted and then as it tried to boot up again, it goes off after a second or two. This repeats every time it tries to boot.
I tried recovery and I noticed that if the jumper was in the 2-3 position, the same thing would happen except i hear 3 tiny ticks before it shuts down. And if the jumper was removed, the whole thing would stay on but no display comes out.
After searching other threads around here, I found there were other people who had encountered a similar experience. I've followed several peoples' successful methods to try to recover the motherboard but no luck. Putting everyone's methods together this is what I tried:
1. Unplugged everything (main power, all usb devices, etc.) and drained power by holding the power button.
2. Removed CMOS battery and yellow jumper.
3. Let everything stay idle for half an hour at least.
4. Formatted a USB stick (tried several formats, FAT, FAT32, NTFS. also tried two different sticks) and copied the bios file to the usb stick with that being the only file in the drive. (I used the bios that came with the board)
5. Plugged in the USB stick. (tried all usb ports)
6. Reseated the main power supply to the mobo and all other necessary connections to the PSU. Also plugged in main power. At this point everything is kept to bare minimum: CPU, RAM, Mobo, and monitor connected through DVI port.
7. Power on and hope it starts recovery
8. If failed, rinse and repeat to try other usb ports (occasionally attempting to reset the cmos)
Now for several others this should work fine. But in my case the same result happens every time; No display, but everything else is powered up, fans are spinning. USB does not flicker, and nether does the front LED though.
I'm just asking again in case I've missed a few factors like:
- Does the usb drive's file format matter? Does the port it's plugged in matter?
- Does the bios recovery screen necessarily have to show up for it to start updating? Someone had implied that the screen may not show up and you may have to wait a couple minutes before shutting down, though it's not made certain.
- Someone else mentioned using the hdmi port to get the display. I'm not able to try this as I only have a DVI monitor, guess I'm stuck with waiting for a few minutes and guessing if the recovery was successful?
- Any other things I can try? I'm not ready to give up on this board just yet.
