Asrock p67 pro 3 error code 62

Before you go updating the BIOS read below carefully.

BIOS updates for Sandybridge boards to add Ivybridge support have been known to be problematic if the correct steps are not followed exactly. This is not a problem if you are using an Ivybridge CPU as that would mean the potentially problematic update is already in place. Once that update has been performed all subsequent updates will behave as normal. If memory serves the update process is 2 fold and will continue after the initial flashing stage on the next boot. Removing the flash drive containing the update or powering off the system prior to the second phase completing will brick the BIOS. If you do choose to go ahead with an update and you are using a Sandybridge CPU you must keep this in mind. Use instant flash with the update saved to a fat32 formated flash drive and do not remove the drive or power off the system until it has successfully passed the post process and begun loading the OS. I would recommend allowing it to boot into the OS then restarting at least once from within the OS before powering off the system just to be safe.

Scary as all this may sound the reality is actually pretty simple, the update in question updates 2 elements of the boards functionality requiring a restart between the 2 stages, interrupting between the 2 stages is what causes the issue.

Now all this is moot if you are already using an Ivybridge CPU, in which case go ahead and update to v3.30 if you have not already. It is always wise after an update to allow the system to fully boot before removing the flash drive containing the update or shutting the system down however  Users who follow that basic precaution never encountered the issue I mentioned above.

What BIOS are you currently running? If it isn't 3.10 or greater then you may need to flash to 3.10 first and then to 3.30.

1. You have switched from Nvidia to AMD on the GPU, some threads suggest that not removing the old drivers correctly can cause a 62 post code. Try booting off the old GPU and using DDU (display driver uninstaller) from safe mode. Not sure how this could cause a post code error but I found the same info in a few different places so it's worth a shot. In all honesty though I would just try disconnecting the HDDs and see if it posts without one.

2. Have you tested the new GPU in another system or otherwise know for sure that it is working? You can try cleaning the contacts on the GPU and blow out the PCIe slot with some canned air. If the old GPU had been in the system for a long time it is possible some dust may be causing poor contact.

3. Make sure no peripherals are connected to the system, apparently some USB devices can cause the 62 post code in conjunction with certain GPUs.

The BIOS version should remain on 3.30 as it will have maximum compatibility for your setup.  I am afraid this list isn't as helpful as I would have liked
