Gigabyte GA-P67A-UD5 startup fail (blinking cursor)

post #1 of 10
Thread Starter 
I've had this four times in the last few days. Start the computer up, get the Gigabyte BIOS startup screen, and then black screen with blinking cursor and then ... NOTHING. It sits there doing nothing at all. I reboot and reboot, no difference.

If I go into BIOS (with F12) and come out, then the next boot it'll startup.

One time while I was in the BIOS, I got a red warning come up that said something about overclocking settings having failed and that I should press F6 to restore original settings. I did that, saved, exited, rebooted and it worked again. But it wasn't permanent, I think that was #2 of 4 occasions that this has happened.

So now when I startup, it seems to be 50/50 whether I see a blinking cursor or "Loading Operating System".

The weird thing is, I haven't overclocked anything at all. I made sure I got a processor, motherboard and graphics card that were all overclockable, with the intention of doing that in a year or so, but so far I haven't done anything.

Any ideas? So far I've tried some BIOS things I think might help, like I added a 2 second delay before it looks to the Hard drives during bootup, and I disabled fast boot. These were in response to the problem though and I'm not yet sure if they've helped.

I wonder if it could be my usage of the AMD GPU Tool. I have it set to run in Windows startup and I use it to set memory speed to 450MHz because the speed of 300MHz that my graphics card idles at is too low and causes dual monitor flicker. Setting it to 450 cures that, but I suspect I'm not just setting the idle speed, I'm setting the overall speed and not giving it a chance to go higher. I really don't know what I'm doing when it comes to that tool, but I know if I set 450 then my monitor flicker goes away. Too scared to flash the graphics card bios at the moment.

Sounds like a definitive motherboard problem to me.

Take out the CMOS battery. If that doesn't work, RMA it.

Bad luck. Sorry, man.

Try this:

- Take out one set of RAM so that you are only running on 8GB.
- Boot up and double check in your BIOS that your voltages are set up properly. Remember, Sandy Bridge requires RAM that runs on 1.5V to be on the safe side.
- Try to reboot a few times and confirm whether if you still have the booting problem or not.

If you still have the problem, try swapping the RAM sticks and see if that helps. If the problem ceases, then you may not have enough voltage going through to support all four RAM slots being populated. As for which voltages specifically, I am not sure, but the above should help to sort out if it is related to the RAM or not.

Good luck with everything!

I get this every so often and the solution is stupid.

Check your boot order.

flash your main bios to your backup BIOS. During POST hold down atl+f12 and it'll ask you if you want to flash the main BIOS to the backup BIOS. my USb keyboard don't allow me to do this, but my PS2 keyboard works fine. Some USB keyboards work as well.

So, I had a look in the BIOS settings and made a few tweaks that I think might have helped Not enough cold boots to make a definitive conclusion yet, but good so far (3/3).

I added a 2 second delay before it looks to the hard drives. I turned off "Halt on any error". The boot sequence was as desired (CD, HDD, USB HDD). I also turned off the fancy startup screen so I can see the old-style messages about discovered hard drives and memory etc, there may well have been a warning/error message there but I wouldn't have seen it because I was seeing that crummy low-res bootup screen instead.

Hopefully those measures will have resolved it. If not, I'll look into trying the above (great) suggestions.

Btw, what will backing up the BIOS to a backup BIOS do for me? Isn't that only useful in case my battery dies (or is taken out) and I lose my settings and want to restore them? Presumably the backup BIOS is [something equivalent to a] EEPROM.

I did notice in the BIOS settings something about copying between CMOS and BIOS, which confused me a bit. Not sure what that's about. I also use a USB keyboard (I don't think I even have any PS2's around anymore) so hoping Alt+F12 works if I need it to. All the single keys (F12, Del etc) work to let me into the BIOS settings, so not sure why Alt+F12 wouldn't.

might try disconnecting and reconnecting your harddrives....

I would have expected some kind of "no boot system found" error if the drive connectors were loose, but I'm going to do it anyway because I did have to do some drive swapping a couple of weeks ago

Things are looking good so far, I've had 6/6 successful boots in the last 3 days or so. I guess turning off "halt on any error" or "2 second delay before looking at hard drives" or the "f6 to restore settings" appears to have resolved the issue. Too early to say definitively, but it's a good sign. Before that I was more or less on a 50/50 situation of whether it would boot or flash a cursor at me. Just one future blinking cursor and I'll know it wasn't those things that cured it, instead it was just luck. Then I'll try checking the hard drive cables, swap the ram around a bit and other things suggested in the thread above.
