z87 Extreme 4 No POST making changes to BIOS

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm using a i5-4670k with the z87 Extreme 4.

I've been having this issue for awhile and been banging my head against the wall and no solution I've been able to find has worked. Little backstory:
A few months ago I was having issues with the computer not POSTing sometimes. I would get different error codes on the board ranging from memory to an error code that didn't come up with anything. I switched to the backup BIOS and things started working correctly, so I flashed BIOS B to BIOS A and things started to work again.

Recently I started having the same issue again, turns out that it that it occurs when I try to do the presets for OCing, or set it myself or update BIOS the computer no longer POSTs. I can't figure out why this isn't working anymore, below is a list of things I've tried:

1. Updating the BIOS via USB and through the GUI - No POST after restart
2. Setting the OC preset to the lowest setting, also manually OCing to .1 Ghz higher - No POST
3. Resetting CMOS via battery and jumper
4. Flashing the BIOS B back to A again, OCing doesn't work from BIOS B either

This worked fine in the past and everything works fine if I don't touch the BIOS settings. I even replaced my PSU after having the problem the first time thinking that was the issue. I'm at a loss at this point and looking for any other advice before I cut my losses and have to purchase a new board.

Thanks.
