Hello, I Recently gave an old computer with this MB to someone, and for some reason they created a user and admin bios password. After they did this, they have a black screen with a pixel trail following mouse whenever they enter BIOS, after entering their password. I was able to re-create this issue with another a-320m motherboard I have. Is there any way to fix this (I assume a bios reset will, but want to make sure)

update again heh, fixed my removing cmos battery and reinstalling. I assume it was having resolution issues or something, but no idea why. password is gone now and so is black screen issue, but (I tested it again), setting a bios password still causes the issue. No big deal, because I dont know why anyone would use one, but weird nonetheless.
