First off clear CMOS, preferably via the battery removal method to clear erroneous data completely. If you still have issues after that then post back.]]> Wed, 17 Feb 2016 02:27:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=2022&PID=10467&title=motherboard-slow-to-post-after-power-failure#10467 <![CDATA[Motherboard slow to POST after power failure : The power went out briefly last...]]> https://forum.asrock.com/forum_posts.asp?TID=2022&PID=10466&title=motherboard-slow-to-post-after-power-failure#10466 Author: ctilley79

The power went out briefly last night.  When I turned the computer on the motherboard would not boot. It stayed on the ASROCK screen for minutes.  After cycling power a few times, the motherboard finally entered an "automatic repair mode" where eventually the computer restarted and I was able to finally boot my machine.

Now when I restart my machine, the motherboard takes about 3 times as long to POST. After a few minutes it finally boots into Windows.  Once in windows everything works as expected, but the long boot times is not acceptable.

One thing I noticed after initial power up is that my USB keyboard had no power. After I unplugged the keyboard and plugged it back in, that finally worked.  Another thing to note is once I got into the bios setup screen,  there is considerable lag trying to select items.

Any ideas what I can do to fix this? Or where I need to start troubleshooting?
