| " rel="nofollow - Since 1.50 I can't get into the UEFI after changing the default settings. The system stops with AB on the LED if I hit the key to enter the UEFI on boot. I also tried using the Windows 10 restart to UEFI option with the same result. If I power down and I hit the CMOS reset button I can get back in to set stuff but that isn't fun each time. I tried removing all USB and SATA cables except for my mouse and keyboard but that didn't make a difference. I'm pretty sure it is something wonky in this UEFI version but was just wondering if anyone else has run into this? |

| I ended up messing around with it some more. I wasn't changing any crazy settings, very few actually. What I ended up discovering was that if I changed the delay time to 5 seconds to enter the UEFI I could get in. I'm not sure why this changed with this version because I never had a problem before. Now I don't have any problem getting in. |

heheh i dont even have "fast boot" or "ultra fast boot" enabled because the restart to UEFI app doesn't work for me but i've havent tried it on 1.50 total headache altogether especially on failed overclocking you'll need to do a failed boot 3 times and wait for the windows special boot up to make it go to UEFI and sometimes that doesn't even work for me resulting to a reset cmos XD -------------
