Make sure your power cable is disconnected from your PC or turn the power switch off on the PSU. Then hold the power button down on your PC for a good 10-15 seconds. Then try clearing your cmos via the jumpers and let the jumper sit there for a few seconds .. then power back up your pc and spam the del key. If you still can't get into the bios .. then turn power off/unplug, hold power button again and then pop out your cmos battery and let it sit for a bit .. some say 24hours but I've never had it out for more than a couple minutes and it cleared ..

pop battery back in and fire up your pc and hopefully cmos is cleared now]]> Sun, 15 Mar 2020 11:37:34 +0000 https://forum.asrock.com/forum_posts.asp?TID=13860&PID=73589&title=help-asrock-b450mhdv#73589 https://forum.asrock.com/forum_posts.asp?TID=13860&PID=73588&title=help-asrock-b450mhdv#73588 Author: Juliano

My computer doesn't start!
I recently bought this mb, made the instalation etc.
First i wasnt getting sound from the gpu (was connect trough hdmi).
I tried some things with no result, them i went to the bios. In the advanced page - amd cbs - nb common there was about the discret gpu audio disable, i enabled that. The audio start to work properly.
But because im (very) stupid, i went to the bios again to see the others options. In the amd pbs, trying to known the features, i modify the 'pcie x16 switch' to gen2, and the 'pcie promontory switch' to gen2.
Now the computer doesnt start, i set the jumper to clear cmos, but still nothing.
There is something that i can do?]]> Sun, 15 Mar 2020 10:58:46 +0000 https://forum.asrock.com/forum_posts.asp?TID=13860&PID=73588&title=help-asrock-b450mhdv#73588
