Failure to POST - Gigabyte EX58-UD5

[THERESONATOR]

My specs are in my sig.

Had my computer about a year now. Lately I been having trouble. Sometimes when I get a power cut and turn the computer on it fails to post. It doesn't do the memory test and if you leave it there it just restarts itself over and over. The (usb microsoft reclusa) keyboard doesn't work either.

What I do to remedy it is turn it off, unplug everything, press the reset CMOS button at the back and plug in my old Microsoft PS/2 keyboard. Usually that works and if not I rinse and repeat and get there in the end. Seems that when it starts working I wouldn't have needed the old keyboard but who knows.

It started happening ever since I started putting my computer on standby and getting power cuts. I get power cuts frequently because I use a key meter for my electricity and we frequently get on emergency credit and run out .: no power. Now it happens even when I just have my computer on and the power goes out. I don't even put it on standby anymore.

We have surge protection FWIW.

Do you think I should try and get a replacement motherboard? Do you think its something other than the motherboard? How do I stop this happening?

I'm in the office but I'll try to be quick.

Just because you have a surge protector is no guarantee of damage done or not done by the consistent loss of power.

Things that you can check off the top of my head though;

Check voltages and make sure they are in spec under idle and load for all components.
Check temperatures and make sure they are in spec under idle and load for all components.

I cannot see switching from a ps2 to usb keyboard making a difference unless either or has been shorting. Which may possibly cause voltage irregularities.

And follow up question; Have you overclocked the PC?

Heh, someone I know just RMA'd a Gigabyte X58 board for this exact problem. If you do searches you'll find that it has been somewhat common over the past couple of years for Gigabyte boards. I believe it is a failure to POST that triggers it. The board then tries to do a BIOS recovery (that "dual BIOS" thing) and it fails, so it is stuck in an endless loop trying to do the BIOS recovery. Sometimes you can change something about your setup to get the board to get past that (if it detects a change in configuration), but othertimes it will never get out of the loop and you have to RMA.

It's just something about Gigabyte boards that does this. Other boards have issues too, for instance it is somewhat common for Asus boards to get a "chassis open" error and lock on POST.

Wondering whether it can have knock on effects. Now my hard drive has also failed. Graphics card, hard drive, god knows what else.

Get a UPS that can run your PC (without power from the wall outlet) for at least 10 or 15 minutes, then will shut down Windows automatically.
APC or Tripp-Lite are reliable brands. Get one with at least a 1000VA rating.

What's the purpose of that?
