    <![CDATA[<strong>Author:</strong> <a href="https://forum.asrock.com/member_profile.asp?PF=1118">centaur555</a><br /><strong>Subject:</strong> 1195<br /><strong>Posted:</strong> 11 Nov 2015 at 2:48am<br /><br />Something very very weird has just happened.<br><br>I've tried again to flash the 1.70.<br><br>Success message, then the boot loop as before.<br><br>Due to your suggestion I've pressed the Clear CMOS Button on the IO Panel.<br><br>That didn't help right away, so I switched the PSU off.<br><br>Turned it on again, but the PC didn't go on. Switched off again, try to turn to no avail.<br><br>Switched off, waited 2 minutes, tried to switch on - nothing.<br><br>Was really worried that the MB was somehow damaged and I would have a lot of mess replacing it (removing, installing CPU etc).<br><br>Then I have used the jumper on the MB to clear CMOS. Turned ON the PSU and the PC turned on, and went into the bootloop. Ok, at least it's in half-working state again.<br><br>I've got a phone call so was busy for 20 minutes. Came back and I see&nbsp; Windows 10 has booted! Did a shutdown. Turned the PC on and could enter the BIOS, and I see 1.70 as version. Configured Bios, saved, and Windows 10 booted again.<br><br>So it's working now. All very weird, and I'm afraid to do an UEFI update ever again! I hope I don't need to do it anytime soon!<br><br>p.s.<br><br>CSM was always on.<br><br><span style="font-size:10px"><br /><br />Edited by centaur555 - 11 Nov 2015 at 3:41am</span>]]>

In my situation, I had the CSM option disabled, and it seems a UEFI/BIOS update does not like to be done with that option set to disabled.<br><br>What I did to overcome it was while the PC was on during the on - off cycle, was press the Reset button on the PC. That helped sometimes, but not always, but is worth doing and is safe to do.<br><br>Another thing I did that helped me, <i><b>and is normally something that is not recommended</b></i>, is I pressed the UEFI/BIOS clear button while the PC was in the on - off cycle.<br><br>Your board has a BIOS reset button on the board's IO panel. So you can easily press that without opening up the PC.<br><br>You could also try turning off the PSU, since the BIOS update was complete, there is no danger in doing that.<br><br>Let us know what happens. I really don't think the 1.70 UEFI has changed the memory compatibility. If it did, you would see a POST code on the Dr. Debug display of 50 or 54, and the PC would not shut off.<br>]]>
