Pc won't even post

Luke_Bowman · 10 Aug 2014 at 15:42

So on Friday I finished my watercooling on my rig with two new cards, booted up, Oc'd the cards roughly and then went to sleep.

Yesterday and today I've spent all my time trying to get it to even post again.

No beeps from the mobo and getting a debug code 62 from the onboard LED.

Read up on this and seems to be a gpu issue so removed the gpu's and tried with on board which let the Pc post.

So what gives? If the gpu's are dead why did it boot and work fine Friday? Surely they haven't just died?!

I'm guessing you tried reseating the GPU's? maybe try to see if it posts with just 1 GPU, have you done the norm of resetting CMOS, and resetting the GPU OC to default.

Luke_Bowman · 10 Aug 2014 at 15:49

Resat the gpu's, cpu and even the ram.

Cleared cmos but can't boot so I can't reset the gpu overclocks

Luke_Bowman · 10 Aug 2014 at 15:49

Also I can't try one gpu as I've run a solid pipe between gpu's which makes it very awkward

What motherboard do you have?

Luke_Bowman · 10 Aug 2014 at 15:54

Gigabyte Z77X-UP7

Your GPU's could possibly be dead

If you have access to another computer/GPU you can test to see if it is your PCI-E slots failing, or your GPU's.

Just bought the gpu's, I'm ****ed.

I'll throw in a 770 to test the slots

Luke_Bowman · 10 Aug 2014 at 16:14

Working with a 770.

Annoyed that new cards aren't working

You may have over tightened the water blocks.

Am sure I had a similar issue...

Luke_Bowman · 10 Aug 2014 at 16:23

One beep which indicates post from mobo and no debug code when plugged into gpu 2's dvi port.

However no display as this is gpu 2

Luke_Bowman · 10 Aug 2014 at 16:25

Plugged back into gpu 1 and got a boot?

What the hell?!

Luke_Bowman · 10 Aug 2014 at 16:27

Restarted and now no boot again

Luke_Bowman · 10 Aug 2014 at 16:30

Pretty sure the debug code is b2 aswell. Not 62 as I thought

Luke_Bowman · 10 Aug 2014 at 16:31

Legacy option ROM initialization

Luke_Bowman · 10 Aug 2014 at 16:35

So I'm lead to believe that this is a problem with the gpu's BIOS. How do I flash a stock bios onto the card or update/fix it?

Trying to flash now but not much luck

Luke_Bowman · 10 Aug 2014 at 17:33

Flashed and working now but no CrossfireX?

Luke_Bowman · 10 Aug 2014 at 19:27

Sorted now. What a fiasco
